Economic information

Comments on the geologic information

  • Geologic Description = The country rocks in the area of this occurrence are Lower Cretaceous to Upper Jurassic, monotonous, intensely deformed and locally highly metamorphosed turbidites. The occurrence consists of copper- and nickel-bearing sulfide minerals disseminated in the sedimentary rocks (Clark and Cobb, 1972).
  • Age = the sulfide minerals may be syngenetic with their Lower Cretaceous to Upper Jurassic sedimentary host rocks.
