Bulk compositional controls on mineral assemblages in metamorphosed ore deposits: an example from the LaRonde-Penna gold-rich VHMS deposit, Quebec, Canada

2019 · Digital Collections of Colorado (Colorado State University)

The hydrothermal processes driving alteration during the formation of VHMS deposits, and therefore the overall geochemistry, mineralogy, and geometry of alteration halos, are reasonably well understood. However, less is known about the effects of metamorphism …
