Geologic structures

Type of structure Local
Structure description 2 Faults W/1 - 2 M Thick Zones Of Deformation. Anticline W/Axis Oriented E.W.

Controls for ore emplacement

  • E - W - Oriented Anticline Is Locus Of Mn Deposit

Comments on the geologic information

  • GEOL.DESC: CRENSHAW IS CONTAINED IN CARBONATE VEINS WHICH FILL SMALL FRACTURES IN THE WESTERN BODY OF THE MN DEPOSIT. THESE FRACTURES ARE STOCKWORK & PARALLEL. PRESENCE OF CINNABAR BEARS NO RELATION TO GRADE OF ADJACENT MN

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic
Significant No

Mining district

District name Ananai Mine

Comments on the production information

  • *THE GRADE OF HG REACHES 10 % ONLY WITHIN THE VEINS. FOR THE ROCK AS A WHOLE, THE GRADE OF ENRICHEMENT IS QUITE LOW. THE MINE WAS MOST ACTIVE FROM 1935 TO 1939

Deposit IN ONE AREA, THE DEPOSIT IS ACCOMPANIED BY PIEDMONTITE AND GLAUCOPHANE, AND WAS ALTERED DYNAMICALLY BY THEM. BUT THE RELATIONSHIP BETWEEN THE ORIGIN OF CINNABAR AND THIS METAMORPHISM IS UNCLEAR
