Comments on the geologic information

  • Geologic Description = Several felsic dikes or sills cut mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group in the higher parts of the Little Taylor Mountains (Cady and others, 1955, p. 71, plates 1 and 6). At a locality a little northwest of the summit of the Little Taylor Mountains, the felsic sheets trend northwest, and dip southwest, parallel to the enclosing sedimentary rocks. The felsic intrusions and the enclosing sedimentary rocks are strongly silicified and pyrtitized. 'Traces of copper' were also noted by Cady and others (1955, p. 122) in the Little Taylor Mountains. For this record, it is assumed that at least a little gold is present in the altered rocks.
  • 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.
