Comments on the geologic information

  • "The deposit is hosted within a fault-bounded wedge of protomylonitic quartzo-feldspathic gneiss exposed along the northwest margin of the Danville Triassic Basin in Virginia." (Jerden and Sinha, 1999)
  • "Several working hypotheses are being considered for the origin of the mineralization. These include hydrothermal activity associated with waning stages of Leatherwood magmatism, magmatic and/or hydrothermal activity associated with Paleozoic faulting, and mineralization by fluids derived from the adjacent Triassic Basin." (Aylor et.al., 2009)
