Identification information

Deposit ID 10307660
Record type Site
Current site name Blue Streak

Geographic coordinates

Geographic coordinates: -131.48577, 55.36074 (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 500 feet. It is approximately 0.3 mile inland from the west shore of George Inlet, about 2.7 miles northeast of the north mouth of Herring Bay, and 1.6 miles southwest of the mouth of Beaver Falls Creek. The site is in section 18, T. 75 S., R. 92 E., of the Copper River Meridian. It corresponds to loc. 81 in Elliott and others (1978). The location probably is accurate within about 0.1 mile.

Comments on the geologic information

  • Geologic Description = The country rocks in this part of Revillagigedo Island are marine, pelitic phyllite and schist that are intruded by Cretaceous stocks, sills, and dikes of feldspar-porphyritic granodiorite, and by a stock and probably related plugs of Tertiary gabbro (Berg and others, 1988). The strata and some of the granodiorite were regionally metamorphosed to greenschist grade in Late Cretaceous time. These regionally metamorphosed rocks subsequently were locally contact metamorphosed to hornblende hornfels near the contacts of Cretaceous granodiorite plutons that were emplaced after the regional metamorphism, and then more widely remetamorposed to hornblende hornfels near the contacts of the Tertiary gabbro. The premetamorphic age range of the pelitic strata is uncertain. Berg and others (1988) assign them a Mesozoic or (Late) Paleozoic age; Brew and Ford (1998) and Crawford and others (in press) assign them to the Gravina belt, of Late Jurassic or Cretaceous age. According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in a Tertiary gabbro stock near its contact with pelitic metasedimentary rocks, was staked for Au, Cu, and Ni. No other information about it has been made public.
