A symposium titled “Phase Relations, High P–T-ometry, and Plate Pushing” was held at the 2003 Geological Society of America Annual Meeting as a tribute to Professor W. Gary Ernst, whose teaching career at the University of California at Los Angeles (1960–1989) and Stanford University (1989–2004) enriched the lives of thousands of undergraduate students and dozens of graduate students. One hundred and nine presentations in three oral sessions and one poster session were made by Gary’s former students, colleagues, and friends. This volume is a collection of papers that center on the geotectonic themes showcased in the symposium and reflecting the diverse interests and prodigious publications of Gary Ernst; they concern the geologic history of units formed or exposed primarily due to subduction-zone tectonism. Papers are grouped starting with those that focus directly on subduction-zone tectonics, followed by studies of terranes exposed largely because of movements at convergent margins |
