INTRODUCTION

This CD contains a compilation of geological maps and supporting data tables for the eastern part of the Bella Coola map-area and adjacent regions in west-central British Columbia. The compilation encompasses more than 12 000 km² and straddles the boundary between the Intermontane and Coast Belt geomorphologic provinces. Geological mapping and data collection for the various maps on the CD was undertaken under different programs, including the Bella Coola Targeted Geoscience Initiative (TGI) Project, the British Columbia Rocks to Riches Program, and Cordilleran Energy and Minerals Project (Y15), administered by the Geological Survey of Canada.

The Bella Coola TGI Project was a jointly funded mapping program undertaken during the period 2000-2003 between the Geological Survey of Canada (GSC) and the British Columbia Geological Survey (BCGS). Additional support was provided by the University of Wisconsin–Eau Claire (UWEC) and the Pacfic Centre for Isotopic and Geochemical Research (PCIGR) at the University of British Columbia (UBC). The objective of the Bella Coola TGI project was to update the geology in the region around Bella Coola, with the goals of unraveling the region’s complex geological history and assessing prospective rock sequences for volcanogenic massive sulphide and copper porphyry potential.

As a result of favorable mineralization results obtained in the more northerly parts of the TGI project, subsequent geological mapping was authorized in southern Whitesail Lake map-area (93E) under the British Columbia Rocks to Riches program during 2003 and 2004. This project included funding from the province of British Columbia as well as the GSC, the UWEC, and the PCIGR. Regional mapping at 1:50 000-scale carried out under this program adjoins the results of the Bella Coola mapping program.

Results of fieldwork activities associated with these projects have been published in a number of GSC Current Research and BCGS Geological Fieldwork papers, as well as Open File maps. This CD is a comprehensive collection of those contributions as well as the final project maps, a valuable resource for users requiring geoscience data for a large region of west-central British Columbia.
