Geologic information

Identification information

Deposit ID 10003484
MRDS ID A106242
Record type Site
Current site name Kings River

Geographic coordinates

Geographic coordinates: -148.50268, 61.94958 (WGS84)
Relative position Reported by Jasper (1965) to be north of east fork of Kings River. Accuracy is poor, but based on the geologic map of Winkler (1992) the coordinates should be within a 2.5 mile radius.

Comments on the geologic information

  • Geologic Description = Jasper (1965) reports that a prospector noted occasional blebs of malachite and chalcopyrite in and above a Late Triassic(?) unfossiliferous and massive to poorly bedded limestone. Locally the limestone occurs as lenses as much as 30 m thick in shear zones within the Early Jurassic to Late Triassic(?) Talkeetna Formation. The extent of mineralization is not known. When Brooks (1918) first reported this occurrence he reported, based on vague data, that the deposit was similar to the occurrence on Moose Creek (ARDF number AN066).
  • Age = Late Triassic or younger; the mineralization is in limestones within the Early Jurassic to Late Triassic Talkeetna Formation.
