| Summary | (Plain Language Summary, not published)
This publication presents bulk geochemistry plots for granite-like rock samples taken from within central Yukon. The samples all date to the late
Triassic (200-205 million years ago) and early Jurassic (180-200 million years ago) periods. Granite-like rocks of similar age within British Columbia are associated with a very large proportion of Canada's economic copper and molybdenum ore
deposits, and significant quantities of gold. However, within Yukon very little mineralization has been positively identified, and only one operating mine is hosted within these rocks. This presentation demonstrates that Triassic to Jurassic rocks
within Yukon have chemical signatures that would normally be associated with such mineral endowment, but suggests that they may have formed as a deeper level within the Earth than those seen in BC. |
