Symposia

  1. They Say That "Breaking up Is Hard to Do": Geological, Geophysical, and Remote Sensing Investigations of Continental Rifts.
    Mohamed Abdelsalam, John Hogan, Kelly H. Liu,
    Missouri University of Science and Technology (MS&T).
        Continental rifting and the development of passive margins is an integral component in the plate tectonic paradigm. Understanding the formation and evolution of rift basins is also of great interest to the petroleum industry as these setting typically are the loci for accumulation of large amounts of sediment and are commonly are productive targets for hydrocarbon exploration. However, the processes which initiate the formation of continental rifts (e.g., mantle driven versus far-field extensional stresses) and processes which can sustain extension to the point of breaking up continents rather than forming aulacogens, remain the subject of considerable debate. This session seeks contributions of such topics related to continental rifting as (but not limited to) magma assisted rifting, the role of preexisting basement structures, initiation by mantle plumes, the effect of changes in lithospheric rheology, and the transition from initiation of rifting to a self sustaining ocean spreading center.
  2. Advances in the Chronology, Correlation, and Stratigraphy of Pre-Wisconsinan Glacigenic Sediments.
    Charles Rovey, Missouri State University; Greg Balco, Berkeley Geochronology Center.
        Improvements in various dating and correlation techniques are now providing absolute ages of glacigenic sediments too old for radiocarbon dating. We seek contributions relating to the sequence and chronology of older (pre-Wisconsin) glacial and interglacial sediments in the Mid-continent region, USA and their possible correlation to marine isotope stages.
  3. Geological Aspects of the Civil War.
    Sherman Lundy, BMC Aggregates; George Davis, Missouri Department of Transportation; Joseph T. Hannibal, Cleveland Museum Natural History.
        This session will include talks dealing with any geological aspect of the American Civil War. Possible topics are battlefield geology, the geological background of those who participated in the war, the role of geological resources in the war, and the geology of Civil War cemeteries and monuments.
  4. Sedimentary Geology of the North American Craton and its Southern Margin.
    Cosponsored by Great Lakes Section, SEPM.
    John Groves, University of Northern Iowa.
        The southern margin of the North American craton has experienced both compressional and extensional tectonics throughout its Phanerozoic history, with sedimentation patterns at any given time responding to the prevailing tectonic regime. This session provides an opportunity for
    specialists to discuss current research on cratonic sedimentary rocks, their basinal equivalents, or rocks of the critical craton-to-basin transition.
  5. Cultural Geology: Archaeological and Historic Building Stones, Sites, and Materials, Terrain, Terroir, and More.
    Joseph T. Hannibal, Cleveland Museum of Natural History; Andrew Bauer, University of Chicago.
        This symposium will include talks that address the intersections of cultural practices and geology. Possible topics are archaeological materials, structures, sites, and terrrain; historic cement, mortar, and concrete; stone used for historic buildings, monuments, and gravestones; the terroir of fermented and distilled drinks; gemstones; and the relationship of the geological landscape to archeological sites and modern cities.

Theme Sessions

Tectonics, Regional Geology, Precambrian Geology, and Planetary Geology

  1. Lithospheric Structure of the Mid-Continent Region: What We Know, What We Need to Know, and What EarthScope Can Tell Us.
    Sponsored by GSA's Geophysics Division.
    G.R. Keller, University of Oklahoma; Kevin Mickus, Missouri State University.
        The USArray component of the Earthscope project is rapidly approaching the Mid-continent region with the installation of seismic instruments scheduled for 2010-2012. With these temporary instruments providing a general background of the lithospheric structure, more detailed seismic and magnetotelluric investigations will be needed to completely understand the nature of the lithosphere. This session seeks to understand the current knowledge of the midcontinent’s lithosphere from all types of investigations ranging from structural, petrological, geochronological, seismological, potential fields and electromagnetic studies. The results of these previous studies will guide where more detailed investigations are needed during the Earthscope experiment.
  2. Geological Evolution of the Sierra Madre Oriental, Mexico.
    Jose Guadalupe Lopez Oliva, Juan Alonso Ramírez Fernández, Universidad Autónoma de Nuevo León (UANL).
        This session will include talks about structural and tectonic evolution of the Sierra Madre Oriental in northeastern Mexico. All geological aspects about the origin of the Sierra Madre Oriental are invited and include sedimentology, structural evolution, geophysical studies, petrological investigations, paleontology and geochronology.
  3. Precambrian Geology of the Midcontinent: Celebrating the Career of W.R. Van Schmus.
    Renee Rohs, Northwest Missouri State University.
        This session will focus on the geochronology or tectonic history of basement rocks throughout the North and South America. The session will be conducted in honor of Randy Van Schmus and his years of research dedicated to understanding the Precambrian crust from Wisconsin to Brazil.
  4. Geology of the Ozark Plateaus.
    Mark R. Hudson, U.S. Geological Survey; Angela Chandler, Arkansas Geological Survey.
        The Ozarks Plateaus region encompasses extensive upland areas of Missouri, Arkansas and adjacent Kansas and Oklahoma and contains widespread karst landscapes developed on Paleozoic carbonates with a core of Precambrian crystalline rocks. These lands host diverse ecosystems, lead-zinc mineralization, and significant energy resources along their southern flank. This session seeks contributions from a broad spectrum of geologic studies concerning the Ozark Plateaus region. Investigations concerned with Paleozoic stratigraphy and tectonic history, the geologic controls on karst landscapes, and mineral and energy resources are all topics welcomed in this session. Investigations may be in the form of topical studies or geologic and geophysical maps or compilations.
  5. Earth, Moon, Mars, and Beyond: Midcontinental Perspectives on Planetary Geology Problems and Research.
    Keith Milam, Ohio University; John C. Weber, Grand Valley State University.
        This session will highlight planetary geology research from geologists in the Mid-Continent of North America, but researchers outside of the NC and SC sections are also encouraged to contribute. Research topics will range widely from terrestrial impact geology to meteoritics, remote sensing to spacecraft missions, and from Earth to other solid bodies in our solar system.

Paleontology, Stratigraphy, and Sedimentology

  1. Current Conodont Research: A Pander Society Session in Honor of Raymond Ethington, Tom Thompson, and Jim Miller.
    Cosponsored by the Pander Society.
    Darwin Boardman, Oklahoma State University; Damon Bassett, Missouri State University; John Repetski, U.S. Geological Survey.
        This session will focus on all aspects of conodont research. The session will be conducted to honor Raymond Ethington, Tom Thompson and Jim Miller and their years of research dedicated to worldwide conodont research.
  2. Ichnofossils: The Marriage of Sedimentology and Ecology.
    Cosponsored by the Paleontological Society.
    Katherine Bulinski, Bellarmine University; Karen Koy, Missouri Western State University.
        Body fossils, while commonly used to characterize paleoecological communities and organismal relationships throughout the fossil record, only represent part of the overall biological picture. Trace fossils, which are common in both fossiliferous and unfossiliferous rock units are important indicators of paleoecology, substrate character and animal behavior. This session will highlight a spectrum of studies dealing with biological and sedimentological interpretations of ichnofossils.
  3. Paleoecology: Variation in Fossil Communities through Space and Time.
    Cosponsored by the Paleontological Society.
    Benjamin Dattilo, Indiana University-Purdue University-Fort Wayne; Katherine Bulinski, Bellarmine University.
        The study of paleoecology illustrates how fossil communities change through time as a function of environmental change, stochastic variation in abundances and diversity, or as a product of long-term evolutionary processes. Importantly, the study of fossil community structure may reveal fine-scale changes to regional environmental parameters that are not recognizable by examining lithology or stratigraphy alone. This session will feature studies of paleoecology at local and regional scales.
  4. Mid-Continent Paleontology.
    Michael Morales, Emporia State University.
        This session is aimed at researchers conducting investigations on various aspects of body fossils (vertebrates, invertebrates, and plants) from rocks of any age in the middle region of North America, i.e,. between the Rocky and Appalachian mountains and between the Arctic Ocean and Gulf of Mexico. A wide range of studies of mid-continent paleontology will be covered, including new taxa or faunas/floras, phylogenetics and taxonomy, paleoecology, paleobiogeography, functional morphology, etc. Microfossils and ichnofossils are excluded from this session because they will be covered in other sessions of this meeting.
  5. Pennsylvanian and Permian Cyclothems of Midcontinental North America.
    John Pope, Northwest Missouri State University; Tom Marshall, Iowa Geological Survey.
        This session will study Pennsylvanian and Permian cyclothems of Midcontinent North America and their relationship to paleoclimate and paleogeography seen as lateral facies changes, as well as the utility of a cyclothemic classification system instead of only a lithostratigraphic classification system. Most Pennsylvanian and Permian cyclothems resulted primarily from marine transgression and regression (mainly due to glacial-eustacy) over a wide area. Classic cyclothems consist of a thin transgressive limestone; thin dark, offshore, phosphatic shale; a thick regressive limestone; various nearshore marine and terrestrial deposits. To the south towards the foreland basinal region in Oklahoma, cyclothems thicken and the number of cyclothems increase. To the north in Iowa, there are fewer cyclothems all separated by paleosols reflecting a position higher on the northern shelf. Subtle sea level changes are often seen in deposits to the north, but are often only recognized geochemically to the south. In the Pennsylvanian Cherokee Group of the Midcontinent, where most cyclothems are missing members or units are lenticular, it is very difficult to differentiate strata with a strict lithostratigraphic classification system. This is where a cyclothemic classification system is more useful, as it also reflects the genesis of the units.
  6. Developments in Early Paleozoic Stratigraphy in the U.S. Midcontinent.
    Robert L. Ripperdan, Saint Louis University; James D. Loch, University of Central Missouri.
        This session will focus on recent developments in our understanding of Early Paleozoic stratigraphic relationships in the U.S. Midcontinent. Papers are welcome from a range of stratigraphic tools including biostratigraphy, chemostratigraphy, and lithostratigraphy, with an emphasis on the correlation and interpretation of chronostratigraphic relationships within, or including the midcontinental region.

Engineering and Environmental Geology

  1. Environmental Microbiology: Intersections between the Biosphere and the Geosphere.
    Melissa Lenczewski, Northern Illinois University.
        Microorganisms are important aspect to understanding the geosphere but are usually overlooked. This session will bring explore the relationships between microorganisms and the environment in which they live.
  2. Is Mother Nature out to Get You? Medical Geology Issues in the Mid-Continent.
    Robert B. Finkelman, University of Texas-Dallas; Syed E. Hasan, University of Missouri.
        Every day we eat, drink, and breathe minerals and trace elements. For most of us this interaction with geologic materials is harmless—perhaps even beneficial—supplying us with some essential nutrients. However, for some, the interaction with the minerals and trace elements can have devastating, even fatal effects. Examples of impacts of geologic materials and processes on animal, plant, and human health from the Mid-Continent region will be presented.
  3. The 2005 Taum Sauk Reservoir Breach: Failure Mechanisms, Flood Effects, Bedrock Exposures, and Current Remediation Efforts.
    Cheryl Seeger, Missouri Dept. of Natural Resources; David J. Wronkiewicz, Missouri University of Science and Technology.
        The catastrophic failure of the Upper Reservoir of the Taum Sauk Pump Storage Facility in December 2005 released 1.5 billion gallons of water into a tributary valley located on the northwest side of Proffit Mountain in Reynolds County, MO. The resulting flood scoured the valley floor along a 1.6-mile section of this tributary valley, and deposited much of this sediment throughout the East Fork of the Black River including Johnson’s Shut-Ins State Park and the Lower Reservoir of the Taum Sauk Plant. Abstracts are invited on all aspects of the Taum Sauk reservoir system including forensic investigations of the embankment failure mode, floodwater hydraulics, exposure of new bedrock geology, sedimentation processes associated with the flood event, remediation, and ongoing rebuilding efforts.
  4. Carbon Sequestration: Research, Deployment, and Commercialization.
    Sallie Greenberg, Illinois Geological Survey.
        This session will examine geologic sequestration projects being conducted throughout the North-Central and South-Central regions, with a specific focus on providing data from a range of project size and development stage.
  5. Water-Rock-CO2 Interactions during Carbon Sequestering Activities.
    David Wronkiewicz, Missouri University of Science and Technology; Mélida Gutierrez, Missouri State University.
        This session will include ongoing research on geochemical, hydrological, and geological processes taking place in sites considered for geological CO2 storage.
  6. The Tri-State Mining District, a Decades-Long Project: Progress, Challenges, and Revelations.
    Gina Manders, Emporia State University; Rebecca Jim, Local Environmental Action Demanded Agency Inc.

       The Tri-State Mining District covers approximately 2,500 square miles in Oklahoma, Kansas, and Missouri, and in earlier times was one of the richest lead and zinc ore producing deposits in the world. It was listed on the National Priorities List in the 1980s due to a multitude of mining related problems that were observed following the cessation of lead-zinc mining in the late 1960s with all mines closing by 1970. Mining operations degraded the surface, leaving piles of sand to gravel-sized mill tailings; piles of overburden bedrock; and impoundments and ponds containing silt-and clay-sized tailings. There are many open mines and subsidence collapse features in the area. Mining activities have changed the area’s hydrology and local stream systems contain mining wastes and impacted sediments. Acid mine drainage and metal-laden surface water is contaminating area streams and the Roubidoux Aquifer is impacted by metals as well. Residential areas are adjacent to mine waste accumulations and suffer from lead-contaminated soils. The character of the mining and mine hazards varies from community to community but the struggles faced in each community in the Tri-State Mining District are unsettling.

    Abstracts are encouraged regarding the Tri-State Mining District with special interest in remediation efforts such as chat injection projects; management and sale of mine tailings; water and soil quality studies; passive water treatment for acid mine water; use of global positioning systems, small-format aerial photography, geographic information software and photogrammetry; and addressing of complicating environmental factors such as the May 2008 tornado.
  1. Applied Geology: Engineering, Environmental, Geotechnical and Hydrogeology
    Terry R. West, Purdue University; Christopher Stohr, Illinois State Geological Survey

Energy and Economic Geology

  1. Devonian and Mississippian Strata of the Midcontinent North America: Sequence Stratigraphy, Paleontology, and Hydrocarbon Potential (Gas Shales, Carbonates, Cherts).
    Darwin R. Boardman II, Oklahoma State University; Salvatore J. Mazzullo, Wichita State University; Brian Wilhite, Woolsey Operating Co.; Jim Puckette, Oklahoma State University.
        Devonian and Mississippian non-conventional petroleum reservoirs have become among the best of the nation’s most promising onshore exploration targets during the last ten years. The proposed sessions seek contributions on the petrography, biostratigraphy, reservoir characterization and sequence stratigraphy of Devonian and Carboniferous strata of the North American Midcontinent (e.g., Woodford-Chattanooga Shale, Barnett Shale-Caney Shale-Fayetteville Shale, Cowley Facies, Mississippian Cherty Carbonates, and Mississippian Bioherms).
  2. Ore Deposits of the Central U.S.: Origin, Mining, and Environmental Remediation.
    Martin Appold, Kevin Shelton, University of Missouri–Columbia.
        This session aims to highlight current research on ore deposits of the central U.S., including their geologic origin and characteristics, mining practices and exploration, the environmental impact of mining, and remediation efforts.

Geoscience Education

  1. Issues in Geoscience Education.
    Cosponsored by Central Section, National Association of Geoscience Teachers.
    Kathleen Bower, Eastern Illinois University.
        This session will present innovative ideas that promote K-16 geoscience education, in-service teacher training and public outreach. Authors are encouraged to submit examples of inquiry based learning, demonstrations, field experiences, workshops and curriculum development.
  2. Arts Integration in K-16 Geoscience Education.
    Cosponsored by National Association of Geoscience Teachers.
    P. Allen Macfarlane, Kansas Geological Survey; Gary Rosenberg, Indiana University–Purdue University.
        K-16 students often more easily connect with geoscience concepts using the visual, dramatic, and literary arts and music than conventional classroom teaching methods alone. Using the arts enhances constructivist approaches because students can explore geoscience concepts more fully to create new understandings. Examples of how the arts can be incorporated into geoscience teaching include using sonification to teach deep time, haiku poetry to teach minerals, visual arts to teach the origins of the Grand Canyon, theatre to teach island formation, and dance to teach the water cycle. This session explores the many ways that arts integration in K-16 geoscience education can be accomplished.
  3. Teaching Sustainability.
    Cosponsored by National Association of Geoscience Teachers.
    David H. Voorhees, Waubonsee Community College.
        As an interdisciplinary issue, sustainability presents some unique problems and challenges for geo/earth-science educators. Sustainability has been broadly defined by the Brundtland Commission in 1987, but it has evolved to take on different meanings in different disciplines and venues. Clearly, the geo/earth-sciences play a significant role in the understanding of the importance of sustainability to our students, but it is as clear it is not the only discipline that is important to this understanding. How many of these interdisciplinary variations and nuances of sustainability do we, or should we, address in our geo/earth-science classes? Is sustainability truly an earth/geo-science class, or should it only be offered as an interdisciplinary class? Finally, what kinds of credible and appropriate resources (i.e., textbooks, internet sites, and exercises) are available to teach sustainability, and at what grade level?
  4. Easy-to-Incorporate Inquiry-Based Activities for the K-16 Classroom.
    Cosponsored by Central Section, National Association of Geoscience Teacher.
    Carrie Wright, University of Southern Indiana.
        Teaching science by inquiry means engaging students’ minds, allowing them to explore science concepts, helping them explain those concepts, elaborating on what they have learned, and assessing their understanding in appropriate ways. Inquiry-based activities promote conceptual change and critical thinking skills by helping students recognize their misconceptions and build knowledge based on personal experience. This personal experience can be in the form of a hands-on laboratory, a long-term project, relating a concept directly to students’ own lives, or another memorable activity. This session features classroom-tested, inquiry-based activities that show evidence of increasing student understanding in meaningful ways.

Hydrogeology

  1. Water Resources Sustainability in the Deep Carbonate Aquifers of the Ozark and Midwest Regions: Will We Have Enough?
    P. Allen Macfarlane, Kansas Geological Survey; John B. Czarnecki, U.S. Geological Survey.
        Deep carbonate aquifers have long been a major water resource and a support for aquatic ecosystems where they are in the near surface environment in the Ozark and Midwest regions of the US. These sources are under increasing pressure for water supply in areas experiencing population growth, contamination from point and non-point sources including mining, and altered recharge areas from changes in land use, all of which could seriously compromise their long-term value. The purposes of this session are to explore the hydrogeology and discuss ideas and opportunities for local, state, and interstate water resources management of these systems. Papers will be accepted that address one or both purposes.
  2. Karst Hydrogeologic Systems of the Central United States and Northern Mexico.
    Cosponsored by the Hydrogeology Division.
    Marcus Gary, Zara Environmental; Benjamin Schwartz, Texas State University–San Marcos.
        Attempts to quantitatively characterize karst aquifers can benefit from the comparison of local and regional systems in diverse settings. The central United States contains important karst aquifers including the Ozarks, Arbuckles, Edwards, and other areas. The objective of this session is to stimulate comparative studies and inter-regional karst system analysis to formulate characterization methodologies.
  3. Aquifer Management Challenges: Unsustainable, Unbounded, Undefined, or Unregulated.
    Susan Stover, Kansas Water Office; Robert Mace, Texas Water Development Board.
        With increasing development and reliance on limited ground water sources, management of aquifers is becoming more challenging. This session will focus on federal, state, interstate and local efforts to improve aquifer characterization, create new management tools, and heighten public awareness of aquifer management challenges.
  4. Tracers in the Environment: Tried and True or Something New — Identifying Issues with the Hydrogeologic System.
    Margaret Townsend, Kansas Geological Survey; Ralph Davis, University of Arkansas.
        This session will cover presentations of new and old tracers in hydrologic studies and what they can tell us about the hydrogeologic system.
  5. Innovative Approaches to Characterization and Remediation of Contaminated, Unconsolidated Aquifers.
    Cosponsored by GSA's Hydrogeology Division.
    Marcia Schulmeister, Emporia State University; Joseph Dom, Kansas Department of Health & Environment; Robert Weber, U.S. Environmental Protection Agency.
        Novel approaches to characterization and remediation of unconsolidated aquifers often evolve in response to local environmental and hydrogeologic conditions. This session will provide a forum for comparison of experiences and outcomes associated with the variety of unconsolidated aquifer types found in the Midcontinent. Talks addressing investigations in alluvial, glacial, coastal plain, and buried valley systems are encouraged.

Surficial Geology

  1. Reservoir Science: Sediment and Water-Quality Studies for Effective Management.
    Kyle Juracek, U.S. Geological Survey.
        Reservoirs are important regionally and nationally for several purposes including water supply, flood control, hydroelectric power generation, and recreation. The ability of many reservoirs to meet these needs is compromised by ongoing sedimentation as well as water-quality concerns. Effective management of reservoirs requires an understanding of sedimentation and water-quality problems including the causes and processes involved. As population growth continues and reservoirs age, reservoir science will become increasingly important as the effort to maintain the viability of reservoirs intensifies. In this session, studies addressing various aspects of reservoir science will be presented with an emphasis on sediment and water-quality issues. The intent is to highlight methods used and knowledge gained as pertaining to specific reservoirs and reservoirs in general.
  2. Speleogenesis, Processes, and Records in Karst Systems.
    Kevin Stafford, Stephen F. Austin State University; Matt Covington, University of Minnesota.
        Karst systems can exhibit complex diagenetic records as a result of multiple phases of speleogenesis and deposition. This session examines the diagenetic evolution of karst systems including hypogene and epigene processes and the relationships between them.
  3. Human Impacts on Fluvial Systems.
    Robert Pavlowsky, Marc Owen, Missouri State University.
        The goal of this session is to investigate the linkages between human activities and the physical and biological condition of river systems. Human populations have a long history of influence on the hydrology, geomorphology, and geochemistry of rivers worldwide. Negative impacts are often attributed to direct manipulation of channel form and flood capacity for management purposes, point and nonpoint inputs of excess chemical and particulate loads, and longer-term changes in runoff and sediment contributions from the watershed related to land use/cover change. It is hoped that a wide range of human impacts at various scales and geographic locations will be included in this session. Acceptable topics include, but are not limited to: channelization and dams, cycles of channel change and recovery, floodplain sedimentation, water quality, sediment geochemistry, ecological health, evaluation of channel restoration measures, and flood magnitude and frequency.
  4. Urbanization Influences on Stream Geomorphology, Hydrology, and Sediment Transport.
    Faith A. Fitzpatrick, U.S. Geological Survey; Jordan Clayton, Georgia State University.
        Human activities associated with urbanization have significant short-term and lasting influences on streamflow, sediment sources and dynamics, stream geomorphology, and aquatic habitat. This session will explore the geomorphic implications of land clearing and construction, flood control, stormwater management, and stream restoration.

Other Sessions

  1. Undergraduate Research (Posters).
