Greetings to all. We invite your participation in a Special Session entitled: Characteristics and causes of low-pressure metamorphism at the upcoming GAC-MAC (Geological Association of Canada-Mineralogical Association of Canada) annual meeting in Whitehorse, Yukon, June 1-3, 2016. Convenors: Dave Pattison, University of Calgary ([log in to unmask]) Chris Coueslan, Manitoba Geological Survey ([log in to unmask]) David Moynihan, Yukon Geological Survey ([log in to unmask]) Description: Low pressure (andalusite-sillimanite type) metamorphism has played a major role in the geological evolution of Earth from the Archaean to the Cenozoic. In this session we examine the characteristics and causes of low-P metamorphism, with special emphasis on the development of large low-P metamorphic belts in the Canadian Shield, the Cordillera, the Appalachians, and elsewhere in the world. We invite field-, laboratory- and modelling-based contributions dealing with, but not restricted to: mineral assemblages and textures; phase relationships; physical and chemical controls on crystallisation histories; rates of metamorphism; tectonic settings and processes responsible for the development of large, low-P metamorphic belts; "Regional-contact" metamorphism; thermal and kinetic modelling; secular changes in the thermal state of the lithosphere; occurrences of kyanite in low-P settings; metamorphism of ore deposits and their host rocks. Abstract submission (deadline January 31, 2016): Abstract submission is now open at: http://whitehorse2016.ca/ Student support: There will likely be some financial support for students. Details can be found at: http://whitehorse2016.ca/student/ Other events of potential interest at the meeting: Other events at the meeting that may be of interest include: 1) A three-day post-conference field trip dealing with tectonics of the Insular and Intermontane terranes in Yukon, 2) Field trips to Yukon's historic mining districts (Keno Hill, Faro, Whitehorse, Klondike), 3) a field trip to volcanogenic massive sulfide (VMS) and orogenic gold deposits on the Alaskan panhandle, and 4) a Workshop on Cordilleran VMS deposits given by Steve Piercey and Bruce Gemmell. For further details on these events, and for any other matters related to the meeting, please go to the meeting web page: http://whitehorse2016.ca/ We look forward to seeing you in Whitehorse!
