GeoFile 2014-08: Carlin-type gold in British Columbia?
Eocene Carlin-type gold deposits (CTGD) in Nevada constitute the second largest concentration of Au in the world. Similar structure-controlled Au and realgar-orpiment showings have recently been discovered in Proterozoic-Paleozoic Selwyn basin strata of the Rackla belt in east-central Yukon. These discoveries raise the possibility of similar occurrences in equivalent settings in British Columbia. This reconnaissance project uses the provincial regional geochemical databases and digital geology to test for Au±As±Hg±Tl±Sb anomalies that may be spatially related to long-lived structures and to platform to deep-water transitions in the Kechika trough (the southward extension of Selwyn basin) of north-central British Columbia.
