|Location and accuracy||This occurrence is centered on the 3,028-foot summit of The Cone west of Ursus Cove. The occurrence is in the NE1/4 sec. 34, T. 7 S., R. 27 W., Seward Meridian, and the location is accurate within about 0.5 mile. The occurrence is number 31 of MacKevett and Holloway (1977).|
Geologic descriptionThis occurrence consists of magnetite(?) in Jurassic quartz diorite (Detterman and Reed, 1980). Immediately north and west of The Cone, the quartz diorite intrudes the Permian(?) to Jurassic Kakhonak metamorphic complex and Upper Triassic Cottonwood Bay Greenstone. Locally, the quartz diorite includes phases as mafic as diorite. Numerous claims were staked in the area, but there is no information about the claims other than that they appear to have been located for a magnetic iron deposit.
