View Entire Bulletin (PDF, 12.65 MB)

 

Bulletin 77 is a synthesis of studies completed on the Iron Mask batholith and the Afton deposit up to 1987.  Emphasis is placed on geochemical and mineralogical aspects of the batholith and the copper-gold deposit, that shed light on their derivation and evolution.  Through theoretical modelling with pertinent thermodynamic data, the unique suupergene alteration features of the Afton orebody are explained.  Applications of the major findings of this study are briefly disucssed with respect to other copper +/- gold occurrences in the batholith.
