Comments on the geologic information

  • Geologic Description = This occurrence is at a warm springs and consists of ferricrete, iron-stained travertine, and graphitic quartzite float (Flanigan, 1998). The temperature of the springs is about 30 degrees C. Samples of silt from the spring are anomalous in lead, zinc, silver, gold, and arsenic. Iron-stained rocks and gossan float nearby contain up to 725 ppm lead, 550 ppm zinc, 1.8 ppm silver, 45 ppb gold, and 45 ppm tungsten.
  • Age = Flanigan (1998) interprets this occurrence to be related to magmatic fluids from the Khotol pluton, based on its proximity to the pluton and its low molybdenum content . K-Ar and Ar/Ar dates for the Khotol pluton are approximately 110 Ma (Flanigan, 1998).
