Geochemistry Of The Dome Mine Ankerite Veins: Insights Into The Multi-Stage Enrichment Of A World-Class Orogenic Gold Deposit, Jessica M. Stromberg

Electronic Thesis and Dissertation Repository

The Dome Mine in the world-class Timmins camp has produced over 16 Moz of gold during its 108 year production history. This gold endowment is the result of multistage enrichment of which the first stage is a set of ankerite veins that extend over 5,400 m in strike and 1,500 m vertically. A deposit wide geochemical study of the Dome ankerite veins was undertaken to characterize their genesis, geochemistry, and role in the deposit mineralization history. Samples and mapping from new and historic mine workings, bulk rock geochemistry, and stable isotope geochemistry were used to constrain the depositional context of …
