Potential radiogenic heat production from Cretaceous and younger granitoid plutons in southern Yukon

The map presents results for calculations of the potential for Cretaceous and younger granitoid plutons to produce radiogenic heat. The calculations were performed using U, Th, and K concentrations from whole rock geochemical data compiled from literature and from the YGS archives. The objective of this exercise was to identify plutons with anomalously high potential for radiogenic heat production to use as a targeting tool for geothermal resource exploration.
