Hydrothermal Alteration Footprint Of The Monument Bay Project, Manitoba, Canada, Juliana Casali

Electronic Thesis and Dissertation Repository

The Monument Bay (MB) project is a greenstone hosted gold deposit, located in NE Manitoba. Previous studies show significant gold grades in the area. This research aims to characterize and delineate the mineralogical and geochemical characteristics of the hydrothermal footprint and mineralization of MB. Combined synchrotron X-ray fluorescence, synchrotron X-ray diffraction, petrography, and electron microprobe techniques were used to support this study. Results indicate sericite and carbonate are the main hydrothermal alteration minerals with homogeneity in their mineralogical, textural, and geochemical characteristics across the deposit. Also, a strong relationship between Au, sericite alteration, and arsenopyrite grains is observed associating the …
