Description

This compilation includes published Nd, Hf, Sr and Pb (plus minor O, S and C) isotopic data from 1722 whole-rock powders and feldspar separates. About 1200 of these samples are located in Yukon and the remainder are located in British Columbia, Alaska or Northwest Territories. This compilation of whole-rock and feldspar isotopic data builds off of a compilation that Kirsten Rasmussen (2013) did as part of her doctoral thesis at the University of British Columbia. To allow easier integration into a user’s GIS platform, and for greater spatial querying of the data, the “database” is presented as a “flat file” (i.e., shapefile, geodatabase and text formats). This whole-rock and feldspar isotope database will be subject to periodic updates as new data are acquired through ongoing mapping, exploration and other research activities. Any errors, omissions or new data known to users should be reported to the Yukon Geological Survey. Your feedback contributes to improving the accuracy of the geoscience databases for Yukon.
