Geochemical And Petrological Characterization Of The Back Forty Volcanogenic Massive Sulfide Deposit, Anthony Robert Boxleiter
Geochemical And Petrological Characterization Of The Back Forty Volcanogenic Massive Sulfide Deposit, Anthony Robert Boxleiter
Masters Theses
The Back Forty Zn-Au deposit is the eastern-most Volcanogenic Massive Sulfide (VMS) deposit in the Penokean Volcanic Belt (PVB). It is the only VMS deposit found in Michigan, and is located along the east side of the Menominee River in Menominee County (45°26'57.5"N, 87°49'43.2"W). The Back Forty is the most zinc-enriched, copper depleted deposit among the major VMS deposits within the PVB that include Flambeau, Crandon, Bend, and Lynne. This work constitutes the first sulfur isotope study on the Back Forty VMS deposit.
The Back Forty is characterized by massive, semi-massive, disseminated and stringer sulfide mineralization hosted within felsic-dominated volcanic …
