Controls for ore emplacement

  • The Deposit Is In The Silicified-Sericitic Zone Of The Kelsey Porphyry Copper Deposit (Roper, 1973). Mineralization Is In A Shear Zone Striking N10w And Dipping 30-50sw. The Quartz Diorite Is Crumpled Anlong The Shear Zone And Consists Of Light-Green Quartz-Mica And Serpentine Schist Over A Width Of 6-10 Feet. Pinch And Swells Have Formed Along Which Mineralization Has Developed; Mineralization Also Cements Broken Wall Rock And Replaces Schist Along Planes Of Schistosity (Patty, 1921, P. 245).

Comments on the geologic information

  • MINERALIZATION IS IN A SHEAR ZONE IN QUARTZ DIORITE OF JURASSIC-CRETACEOUS (?) SILVER NAIL LAKE PLUTON (FOX, 1970).
