Comments on the geologic information

  • Geologic Description = The country rocks in the area of this occurrence are a tectonically mixed assemblages of Upper Devonian serpentinite, basalt, chert, and gabbro. The deposit consists of pods of massive chromite in serpentinite. Rock samples from the surface contained low chromium, palladium, and platinum values (Balen, 1990: OFR 34-90). The chromite probably was a mag,atic segregation on the ultramafic host rocks.
  • Age = the chromite probably was a magmatic segregation in Upper Devonian ultramafic intrusive rocks.
