Welcome to the Yukon Geological Survey's Integrated Data System (YGSIDS). We are in the process of merging all of our data into one system (see the current state of the conversion process). When this process is complete, the YGSIDS will include all of the Yukon Geological Survey's publicly accessible data.

Map Location


New geochemical data from re-analysis of archived stream sediment samples have been assessed using weighted sums modeling and catchment basin analysis as described in the methodology report that accompanies this map (YGS Open File 2015-10). Both commodity and pathfinder element abundances are evaluated to highlight areas that show geochemical responses consistent with a variety of base and precious-metal mineral deposit types. The results of modeling, completed using two approaches, are presented as a series of catchment maps and associated data files. This release is part of a regional assessment of stream sediment geochemistry that covers a large part of Yukon.
