Comments on the geologic information

  • Geologic Description = T. K. Bundzten (personal commun., 1992) reports that disseminated arsenopyrite, cinnabar, pyrite, and minor gold are in hypabyssal rhyolite about 1 mile south of the Taylor Creek airstrip. Sparse sulfides are also in quartz-tourmaline veinlets that cut the rhyolite. Cady and others (1955, p. 71, plate 1) noted east-west-trending rhyolite dikes or sills on the ridges just west of lower Forks Creek, about about 2.5 miles east-northeast of this occurrence. The felsic hypabyssal rocks intrude mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group.
  • Age = Late Cretaceous or Early Tertiary, the age of felsic plutons in southwest Alaska that intrude the mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group.
