ProgramTargeted Geoscience Initiative (TGI-5) Intrusion/Porphyry ore systems - porphyry processes - mineral markers
Released2021 09 01
Summary(Plain Language Summary, not published)
This Bulletin published by the Geological Survey of Canada contains ten articles summarizing the results of five-year research projects conducted on porphyry deposits in Canada as part of the Targeted Geoscience Initiative (TGI). Porphyry deposits are ore bodies, including past-producing and active mines, associated with intrusive rocks such as granite. They are significant producers of a variety of metals, including copper, molybdenum, tin and tungsten. Nine out of ten papers describe projects conducted in the Canadian Cordillera where most Canadian porphyry deposits occur and a paper on similar, but older deposits in the Appalachians of Atlantic Canada. The main objective of these TGI research projects was to better define the geological conditions where porphyry deposits form and test techniques to detect buried porphyry deposits in support of mineral exploration.
