Geologic descriptionDiffuse, widespread iron-stained zones in mylonitic metavolcanic rocks of the Haley Creek terrane contain disseminated pyrite and possibly chalcopyrite and sphalerite (Winkler and others, 1981 [OFR 80-892-B]). The polydeformed Haley Creek terrane consists of metasedimentary rocks, including marble and metaplutonic rocks that range from peridotite to trondhjemite (Winkler and others, 1981 [OFR 80-892-A]). The protolith ages are not known, but much deformation and recrystallization of the Haley Creek terrane probably occurred in the mid-Cretaceous or later (Winkler and others, 1981 [OFR 80-892-A]). |

Age of mineralization |
Not known; the protolith ages of metasedimentary and metaplutonic rocks in the Haley Creek terrane are not known, but much deformation and recrystallization probably occurred in the mid-Cretaceous or later (Winkler and others, 1981 [OFR 80-892-A]). |
Alteration of deposit |
Oxidation; diffuse iron-stained zones are present. |
