GEOLOGY AND U-Pb GEOCHRONOLOGY OF INTRUSIVE ROCKS ASSOCIATED WITH MINERALIZATION IN THE NORTHERN TAHTSA LAKE DISTRICT, WEST-CENTRAL BRITISH COLUMBIA
The Bulkley Suite of intrusions are spatially associated with numerous important mineral occurrences in westcentral British Columbia. Previous K-Ar dating studies indicated that the Bulkley Suite ranges in age from 70 to 84 Ma (Carter, 1981). The purpose of this study is to better constrain the timing of Bulkley Suite magmatism and associated mineralization in the northern Tahtsa Lake District....
