Comments on the geologic information

  • Geologic Description = Hummel (1962 [MF 248]) identified this locality as an iron sulfide occurrence and part of a group of prospects that contained pyrite, arsenopyrite, and at some of the prospects, pyrrhotite. The sulfides may be disseminated or in veins. The prospect is near or at the upper contact of calcareous schist with a marble layer; the rocks strike northwest and dip northeast (Hummel, 1962 [MF 248]).
  • Age = Probably mid-Cretaceous or younger if in cross-cutting veins.
