Geologic structures

Type of structure Regional
Structure description The Midniight Peak Formation And The Fawn Peak Stock Were Part Of A Cretaceous Island Arc (Riedell, 1979).

Controls for ore emplacement

  • The Ore Consists Of Quartz Stringer Veins In That Are Mineralized To Some Extent (Huntting, 1956, P. 140). The Deposit Is In The Actinolite-Chlorite Zone Of The Mazama Molybdenum Porphyry System. Veins Peripheral To The Porphyry System Generally Trend N10-40e And N70-85w (Riedell, 1979).

Comments on the geologic information

  • THE GOLD KEY MINE IS IN ADESITES OF THE MIDNIGHT PEAK FORMATION, WHICH ARE INTRUDED BY THE CRETACEOUS FAWN PEAK STOCK. THE STOCK IS PROBABLY THE INTRUSIVE EQUIVALENT OF THE VOLCANIC ROCKS (STOFFEL AND MCGRODER, 1990, P. 15).
