Capsule Geology

The area is underlain by Lower Jurassic rock of the Hazelton Group. The north trending Brucejack Fault System is bounded on the west by Unuk River Formation rock. Between the Brucejack fault and a north trending splay fault to the east is a block of Betty Creek Formation rock. A syn to post volcanic K-feldspar-potassium feldspar porphyry intrusion is bounded by these same two north trending faults and is separated from the block of Betty Creek Formation rock to the north by another northwest trending fault (Open File 1988-4).

A 0.61 metre wide vein of rhodochrosite is reported to occur within a porphyritic flow that appears to be located within the block of Betty Creek Formation rock (Assessment Report 499).
