Mineral deposit profiles
Mineral Deposit Profiles provide brief summaries of the types of mineral deposits found in British Columbia. They include descriptions of host rocks, mineralogy, alteration, tectonic setting, associations, genetic models, and exploration guides, and give typical examples with grades and tonnages.
The British Columbia Geological Survey (BCGS) started a mineral potential assessment in 1992 utilizing deposit models for defining and characterizing mineral and coal deposits which exist, or for which favourable geological environments could exist, in the province. These deposit models are being used to classify known deposits and occurrences, to guide experts in their estimation of the number of possible undiscovered mineral deposits, and to group deposits to allow compilation of representative grade and tonnage data.
The BCGS formerly relied on mineral deposit models published by the United States Geological Survey (USGS) and Geological Survey of Canada (GSC). However, it became apparent that some models needed revision, and that there are British Columbia deposit types lacking published models. Hence we developed a set of mineral deposit profiles using the Branch's considerable in-house expertise, with assistance from economic geologists of the GSC, USGS, industry and academia.
These deposit models are called "deposit profiles" to distinguish them from other published descriptions. The deposit profiles were completed in three volumes describing metallic, coal, and industrial minerals and gemstone deposits.
- Volume 1 - Metallics and Coal (BCMEMPR Open File 1995-20)
- Volume 2 - Metallic Deposits (BCMEMPR Open File 1996-13)
- Volume 3 - Industrial Minerals and Gemstones (BCMEMPR Open File 1999-10)
These three volumes were combined.
