Volcanogenic massive sulphide and orogenic gold deposits of northern southeast Alaska

By: , and 



This five-day field trip visits the most significant mineral deposits in northern southeast Alaska. The trip begins and ends with regional transects in the interior Intermontane terranes around Whitehorse, Yukon, and the Insular terranes along the northern Chatham Strait region of southeast Alaska (Fig. A-1 and Fig. A-2; Plate-1). To put the deposits in a regional tectonic framework, the guidebook begins with an introduction to northern Cordilleran geology, tectonics and metallogeny. The foci of the deposit portion of the field trip are Late Triassic volcanogenic massive sulphide (VMS) deposits of the Alexander Triassic metallogenic belt and Paleogene orogenic gold deposits of the Juneau gold belt. Details of the local geology are further elaborated in each segment of the guide book (Days 1-5). The data that provide the basis for the VMS deposit interpretations come from a series of PhD and MSc studies by the Centre of Excellence in Ore Deposit Research (CODES) at the University of Tasmania and the University of Ottawa. These deposit-scale studies are complimented by a long history of regional mapping and research by the U.S. Geological Survey (USGS).
