Summary(Plain Language Summary, not published)
This report presents a dataset comprising almost 200 previously unpublished 40Ar/39Ar analyses and age determinations that were carried out in the Geological Survey of Canada (GSC) Argon Lab facility in Ottawa, Ontario, for samples collected across the southern half of Yukon between 1997 and 2003. These samples were collected as part of several collaborative projects between GSC and the Yukon Geological Survey (YGS; formerly Yukon Geology Program), under the National Mapping Program (NATMAP), Targeted Geoscience Initiatives (TGI), and as part of regular field activities of the YGS. This report constitutes the largest single, modern thermochronology dataset available for Yukon, and generally supersedes many of the older published K/Ar determinations from the 1960s to 1980s compiled in the publicly available YukonAge database.
