Comments on the geologic information

  • Geologic Description = This occurrence consists of two gossan-rich quartz veins, as much as 1.5 feet wide, along northwest-trending joints and fractures in quartz syenite (Bundtzen and Laird, 1991). Sulfide minerals were not identified in these strongly oxidized veins. Samples contained up to 0.3 percent arsenic, 1.5 percent antimony, 353 ppm neodymium, 54 ppm tantalum, and 52 ppm uranium. The host quartz syenite is part of the Late Cretaceous intrusive complex of the Russian Mountains (Bundtzen and Laird, 1991).
  • Age = Late Cretaceous or Tertiary. Veins crosscut part of the intrusive complex of the Russian Mountains. Quartz monzonite from this complex has yielded a K/Ar age of 70.3 +/- 2.1 Ma (Bundtzen and Laird, 1991).
