Geologic structures

Type of structure Local
Structure description Sangre de Cristo fault system

Comments on the geologic information

  • Geology is similar to the Crestone district, which is located a few miles to the northwest (Vanderwilt, 1947). Also similar to mineralization at the San Luis mine in the El Plomo district, Costilla County, Colorado (Benson, 1997). Structurally controlled veins cut Paleoproterozic rocks.
  • Low-angle "detachment" fault present in district and hosts mineralization locally. Fault dips 25-30 degrees SW (Benson, 1997).
  • Gold associated with silicification and fine-grained pyrite mineralization along a low-angle fault structure (Benson, 1997).
