T28. Interdisciplinary Approaches to Assessing Environmental Impact of Mining

JoAnn M. Holloway, Kate M. Campbell, Suzette A. Morman
GSA Environmental and Engineering Geology Division; GSA Geology and Society Division; GSA Hydrogeology Division; Geochemical Society; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division

This session explores interdisciplinary approaches to assessing environmental and human health effects of historical and projected mining activity.

T37. Excursions, Extinctions, and Environmental Change: New Advances in Geochemical Tools Linked to Critical Intervals of Environmental and Biotic Change in Earth History

Cole T. Edwards, Seth A. Young, Jeremy Owens, Benjamin C. Gill
GSA Sedimentary Geology Division; GSA Geobiology & Geomicrobiology Division; SEPM (Society for Sedimentary Geology); Geochemical Society; Paleontological Society; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division

This session will highlight emerging research that broadens our understanding of the links between paleoenvironmental change, recorded in traditional vs. non-traditional isotopic/elemental proxies, with the paleontological record of extinction and biodiversification within the sedimentary record.

T70. The Animas River and Beyond: Balancing Science and Policy in Cleaning up America’s Abandoned Mine Lands

Katie Walton-Day, Robert L. Runkel, Brent Lewis
GSA Geology and Society Division; GSA Environmental and Engineering Geology Division; GSA Hydrogeology Division; Geochemical Society; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division

This session merges scientific assessment with policy implications of historical hard-rock mining, with emphasis on the 2015 Gold King Mine event. Abstracts related to the Animas River Basin and other abandoned mine lands are encouraged.

T129. Mineralogical Evidence for the Co-Evolution of the Geosphere and Biosphere: In Honor of Robert M. Hazen, 2016 Roebling Medalist

Edward S. Grew, John M. Hughes, Nancy L. Ross, Daniel Hummer
Mineralogical Society of America; Deep Carbon Observatory; GSA Geobiology & Geomicrobiology Division; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division; Geochemical Society

In honor of Robert M. Hazen, 2016 Roebling Medalist of the Mineralogical Society of America, this session emphasizes Earth’s rich mineralogical record through deep time as key to understanding the co-evolution of the geosphere and biosphere.

T132. Microfossil Proxies in Earth History (Posters)

Miriam E. Katz, Laurel S. Collins
Cushman Foundation; Geochemical Society; Paleontological Research Institution; Paleontological Society; GSA Limnogeology Division

This session brings together marine and terrestrial microfossil proxy-based research (assemblages, geochemistry, modern analogs) to improve our understanding of evolving oceans, land, and climate through Earth history and the floral/faunal responses to those changes.

T133. New Views of the Paleocene-Eocene Thermal Maximum

Kenneth G. Miller, Miriam E. Katz
Cushman Foundation; Geochemical Society; Paleontological Society; Paleontological Research Institution; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division

This session explores new evidence for the rate and cause of the Paleocene Eocene thermal maximum and attendant carbon isotopic excursion, focusing on intriguing links between impact events and volcanism and geochemical and paleontological responses.

T154. Recent Advances in Understanding Magmatism along and within the Northern North American Cordillera

Matthew E. Brueseke, Jeff Benowitz, Jeffrey M. Trop, Paul W. Layer
GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division; Geochemical Society; GSA Structural Geology and Tectonics Division

Magmatism in the northern Cordillera is the result of diverse tectonic phenomena, including subduction, strike- slip, and extensional processes along convergent and transform margins. This session highlights research in the northern Cordillera aimed at understanding links between magmatism and plate tectonic processes.
