Controls for ore emplacement

  • Mineralization Is Most Extensive In The Brecciated Zone Between The Swakane Biotite Gneiss And Diorite. Sulfide Minerals Are Chiefly Pyrrhotite And Chalcopyrite. Scheelite Occurs As Disseminated Grains, Veinlets, And Small Masses In The Sulfides (Culver And Broughton, 1945, P. 14-15).
