M.Sc. [Earth Sciences] Proposal

"Mineral Deposit Metal Endowment and the Chemistry of Ore-forming Fluids"

by 

James Greene

Abstract:  

The Mount Pleasant W-Mo-Sn deposit is located in southern New Brunswick and consists of two zones: the North Zone and the Fire Tower Zone. The dominant ore metals are Sn in the North Zone and W and Mo in the Fire Tower Zone. Few studies have focused on how the overall metal endowment of an ore deposit relates to the metal concentrations of their ore-forming fluids. In addition, no study has examined an ore deposit in which the metal endowment is spatially separated (e.g., the North Zone and Fire Tower Zone) and temporally distinct (e.g., W-Mo mineralization followed by Sn mineralization). The questions that will be addressed by this study are: i) how is metal endowment related to the metal content of the ore-forming fluids?;and ii) what can we learn about this topic by studying Mt Pleasant? To understand how metal endowment is related to the metal content of the ore-forming fluids, metal concentrations will be determined using two methods: i) direct analyses of fluid inclusions and ii) assessment of metal concentrations in the fluid using chemical analyses of fluorite that precipitated from the fluids. Fluorite has been selected to be the focus on analyses because it occurs pre- and post-mineralization. By comparing the composition of the fluid from both the North Zone and Fire Tower Zone, it will be determined whether two different fluids, or a similar fluid, was responsible for generating the variable metal ratios between the two zones. By studying Mt Pleasant, a greater understanding of the interplay between fluid chemistry and metal endowment will be gained. The different types and generations of fluorite will be used to understand fluid evolution by examining how the metal contents of fluorite and contained fluid inclusions vary in time and space.
