Comments on the geologic information

  • Geologic Description = The country rocks at the Glacier Creek prospect are the Lower Mississippian to Middle Devonian Totatlanika Schist, composed predominantly of mafic and felsic metavolcanic and metavolcaniclastic rocks, minor pelitic schist, and fossiliferous marble (Wilson and others, 1998). The deposit consists of stratabound lenses of massive sulfides in strongly altered rhyolite schist (www.grayd.com, 1999). The sulfide minerals are chalcopyrite, galena, sphalerite. The hostrocks and stratabound massive sulfides indicate that the Galcier Creek prospect is a metamorphosed volcanogenic massive sulfide deposit.
  • Age = The sulfide minerals probably are syngenetic with their Lower Mississippian to Middle Devonian host rocks.
