Book Description

The Alberni-Nanaimo Lakes area lies at the southeastern end of the Vancouver Island Ranges and is characterized by fairly rugged topography accentuated by glaciation. The area covers one of a series of major geanticlinal structures constituting the structural fabric of the Wrangellia terrane of Vancouver Island. This report introduces the geological setting of the Alberni-Nanaimo Lakes area and describes its lithology and stratigraphy, geologic structure and tectonics from the Late Devonian to the Eocene, and metamorphism and alteration in the area's sedimentary and igneous formations. The final chapter reviews the history of mineral exploration in the area, outlines the regional metallogeny, and classifies the types of mineral deposit present in the area. The appendices contain tabulated data, descriptions of mineral occurrences and fossils, and a summary of assessment report work recorded within the area.
