Controls for ore emplacement

  • According To Moen (1973), The Deposit Is In Brecciated And Silicified Black Argillite That Has Been Intruded By A North-Trending Aplite Porphyry Dike, Which Appears To Be Several Hundred Feet Wide. Parts Of The Dike Contain Pods Of Galena And Pyrite That Are Accompanied By Minor Chalcopyrite And Sphalerite (Moen, 1973, P. 37). Rinehart And Fox (1976) Indicate The Deposit Is In A Tertiary Crystal Tuff Intruded By A Tertiary Dike.
