Full Title: Jurassic Magmatism and Tectonics of the North American Cordillera

Editors: David M. Miller and Cathy Busby

There is a growing realization that in about mid-Jurassic time, both magmatism and tectonism were widely initiated in the western North American continental crust, earlier subduction-driven magmatism and tectonics being localized near the plate margin. The 19 papers in this book discuss diverse approaches to characterize the Jurassic tectono-magmatic event, identify variations in its timing and other characteristics from region to region, and consider its ultimate origin in terms of lithospheric processes. Crucial aspects of the Jurassic tectonic events from the Yukon to southernmost United States are described. The lead paper presents a broad synthesis of Cordilleran subduction cycles, and is followed by papers arranged in three groups, from north to south: Canadian Cordillera; U.S. Great Basin; and southwestern U.S. desert regions. Within each group, papers are arranged from magmatic arc eastward to craton. This is an important look into now-eroded initial subduction-driven orogeny of the Cordillera, the precursor to later events that so strongly shaped present geology. Most papers are data-intensive first-order studies, although some fresh synthesis studies are also present.
