The thermal evolution of mountain belts is recorded inthe distribution, origin and ages of magnatism. In this volume, petrologic, isotopic and geochemical evidence is presented to highlight the contribution of igneous rocks to the evolution of the Appalachian Orogen in both Canada and the United States. These papers emphasize the use of modern geochemical and petrologic data to discriminate the sources yielding magmas, and thus the nature of the crust and mantle.

"This volume contains field guides to the 2015 GSA Southeastern Section Meeting's field trips. The guides explore geologic history and visit four regional geologic provinces--the Nashville dome, Blue Ridge, Valley and Ridge, and Cumberland Plateau"--
