Current site name Conkle

Geographic coordinates

Geographic coordinates: -131.68678, 55.55074 (WGS84)
Relative position This prospect is known only from U.S. Bureau of Mines (1977) claim records. Its approximate location is at an elevation of about 200 feet in or near the valley of an unnamed, north-flowing stream that empties into the cove just inside the west mouth of Moser Bay. The site is in section 11, T. 73 S., R. 93 E., of the Copper River Meridian. It corresponds to loc. 43 in Elliott and others (1978). The location is accurate within 0.2 mile.

Comments on the geologic information

  • Geologic Description = The country rocks near this prospect consist mainly of andesitic and basaltic metavolcanic rocks and subordinate flyschlike metasedimentary rocks that are intruded by Cretaceous stocks, sills, and dikes of feldspar-porphyritic granodiorite (Berg and others, 1988). There also are scattered, small, fault-bounded outcrops of Cretaceous ultramafic rocks. The strata were regionally metamorphosed to greenschist-grade phyllite and semischist in Late Cretaceous time, and, near some of the granodiorite contacts, subsequently contact metamorphosed to hornblende hornfels (Brew, 1996, p. 27; Berg and others, 1988, p. 17). The premetamorphic age range of the strata is unknown. Berg and others (1988, p. 17) note that they closely resemble Upper Jurassic to mid-Cretaceous marine flysch and volcanic rocks nearby on Gravina Island. According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be at or near a metapelite-metavolcanic contact not far from a granodiorite plug, was staked for copper and iron. No other information about it has been made public.
