Geologic structures

Type of structure Local
Structure name high angle faulting along western Sangre de Cristo Range
Structure description Sange de Cristo fault

Comments on the geologic information

  • Mineralization appears to be associated with the Sange de Cristo fault zone and other extensional faults of the Rio Grande rift. Mineralized veins have been found only in crystalline basement rocks, not in nearby Paleozoic sedimentary rocks.

Economic information about the deposit and operations

Operation type Surface-Underground
Development status Past Producer
Commodity type Metallic
Significant No

Comments on the production information

  • Production was small, if any, and it was not recorded.
