Mineralization at Galore Creek consists mainly of disseminated chalcopyrite, bornite and pyrite. Biotite and orthoclase are the dominant alteration minerals with commonly associated anhydrite, garnet, apatite, calcite and magnetite.
The mineralization occurs in altered syenites, metavolcanics and brecciated equivalents of these along the contacts of a complex of syenite porphyries which display many characteristics of epizonal intrusions. Exsolution textures of bornite and chalcopyrite indicate a minimum temperature of deposition of 475°C. This leads to the conclusion that the deposit formed at a relatively high temperature and a shallow depth and therefore may be classified as xenothermal. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
