Controls for ore emplacement

  • The Deposit Contains A Black To White, Northwest-Striking, East-Dipping, 2-15-Ft-Wide Quartz Vein In Graphitic Argillite. The Vein Walls Are Generally Well-Defined, But In Several Places The Vein Gradually Grades Into Argillite; The Vein Also Contains Fragments Of Argillite. Locally, The Vein Is Offset By North- And Northeast-Trending, High-Angle Faults. Ore Minerals Are Sparsely Disseminated In Quartz (Moen, 1980, P. 37).

Comments on the geologic information

  • THE VEIN IS IN GRAPHITIC ARGILLITE OF THE PERMIAN SPECTACLE FORMATION OF THE ANARCHIST GROUP (MOEN, 1980).
