| Abstract | The geochemistry and mineralogy of drill core and discharge sinters from the Meager Creek geothermal field suggest that at least two hydrothermal events have affected this area. The earliest of these events is characterized by chalcopyrite mineralization and widespread propylitic alteration of the crystalline rocks which form the geothermal reservoir. A younger event results in the deposition of silica, pyrite, clays, carbonate, and hematite in hypabyssal dikes of the Meager Mountain Volcanic Complex and appear to be related to the present geothermal system. The distributing of Hg + Zn + As, and of Hg and Sr are diagnostic of geothermally altered rocks at Meager Creek and suggest that fractures related to the dikes have been important fluid channels in the past. |
