1 sheet at 1:150 000 scale


This geological compilation covers approximately six, 1:50 000-scale map sheets adjacent to the Coast Belt-Intermontane Belt boundary within the Whitesail Lake map area. The map is based on a compilation of geological mapping conducted by the BC Geological Survey during the Whitesail Project (1987-1990), as well as data available in previously published government reports and university theses. The area is underlain by a diverse assemblage of Late Paleozoic to Cenozoic volcanic, sedimentary and metamorphic rocks, together with numerous plutonic rocks.

 

The map features a collation of available fossil collections and age determinations. It also contains a mineral occurrence database that demonstrates a strong spatial relationship between Cu-Mo mineralization and hornblende-biotite-bearing intermediate intrusions of the Late Cretaceous and Eocene suites.


All publications of the BC Geological Survey are available digitally, free of charge, from this website.
