Structure of the Takla Group East of the Finlay-ingenika Fault, Mcconnell

The study area is located northwest and south of Johanson Lake. bounded to the northeast by the northwcsttrending Lay fault and to the west by the north-northwesttrending Finlay-lngenika fault. The Finlay-lngcnike fault is ii dextral transcurrent fault, and is part of the very prominent strike-slip fault system in north-central British Columbia (Gabrielse, 19X5). This project was undertaken to examine the structures on the cast side of the Finlay-lngenika fault, to provide geological evidence for the dextrid transcurrcnt displacement and to study local deformation associated with it. This report summarizes the results of I50 000.scale geological mapping in July and August 1990 in parts of map sheets Y4DiX and Y4D/9. Fieldwork concentrated on stratigraphic and structural relationships.
