Comments on the geologic information

  • Geologic Description = A zone of brecciated slate is present along a thrust fault that strikes N 68 E, and dips 45-65 N, in Cretaceous slate (Grant and Higgins, 1910). The 6 to 8 ft zone of brecciated slate is cemented by quartz and contains a layer, 1 to 8 inches thick of finely columnar and granular masses of stibnite with associated acicular stibnite crystals and quartz (Brooks, 1916). Stibnite accounts for as much as 1/3 of the mass locally. Ferruginous carbonate is intimately associated with the stibnite. Grant and Higgins (1910) report specimens indicate that the quartz vein was shattered and subsequently intruded by stibnite-bearing solutions. Bedrock is Late Cretaceous Valdez Group metasedimentary rocks.
  • Age = Late Cretaceous or younger; vein cuts Late Cretaceous Valdez Group metasedimentary rocks.
