| Bulletin 100 describes the geology of a 3200-square-kilometre
area covering NTS map sheets 92O/2, 3 and portions of sheets 92O/1,
92J/15, 16, which are mainly within the Chilcotin Ranges of the
southeastern Coast Mountains. The area is underlain by late Paleozoic to
Tertiary rocks that include the oceanic Bridge River Terrane, the volcanic
arc-derived Cadwallader and Methow terranes, ophiolitic rocks of the
Shulaps and Bralorne-East Liza complexes, and the Jura-Cretaceous clastic
sedimentary rocks of the Tyaughton-Methow basin. These assemblages are
juxtaposed across complex systems of contractional, strike-slip and
extensional faults of mainly Cretaceous and Tertiary age. This Bulletin
describes and defines the major lithotectonic units and the structures
that deform and bound them. It also describes the mineral occurrences of
the area, which includes the northern part of the Bridge River mining
camp, and interprets their genesis in terms of the Cretaceous and Tertiary
structural and magmatic evolution of the area. In the final chapter,
regional correlations of lithotectonic assemblages and structures are
discussed, and an interpretive summary of the tectonic evolution of the
southeastern Coast Belt is presented. The report is accompanied by
numerous photos, data tables, maps and illustrations, as well as a 1:100
000-scale geological map of the area with interpretive cross-sections. |
