Comments on the geologic information

  • Geologic Description = Lignite Creek drains an Eocene to Miocene sequence of poorly consolidated, pebbly sandstone, claystone and subituminous coal. The sequence pinches out northward and is overlapped unconformably by Tertiary Nenana Gravel (Wilson and others, 1998). The southern edge of the Lignite Creek drainage basin is underlain by of Birch Creek Schist. Placer gold has been reported in Lignite Creek near the mouth of Frances Creek. The sources of the gold probably are paleoplacers in the Nenana Gravel.
  • Age = Quaternary.
