(Working) Thesis Title: Geochemical and petrographic micro-textural variations in the Sudbury Breccia, Canada: A guide for footwall Ni-Cu-PGE mineralisation?

Thesis Description

Previous research and exploration for Sudbury breccia hosted footwall Ni-Cu-PGE deposits in the Sudbury Igneous Complex have been based upon the concept of increasing degrees anatexsis within the breccia as one approaches mineralisation. Recent work in the South Ranges has suggested this may not always be the case.
Working alongside multinational miner, Vale this project aims link geochemical variations observed in the breccia, with micro-textural changes at varying distances from known ore bodies. The project will include ICP-MS, Electron Microprobe, FeO titration and ion selective emission analysis, combined with field mapping and a new semi quantative image analysis process developed by researchers at the University of Western Ontario.

Thesis Titles:
The influence of magmatic processes on the geochemistry and mineralisation of indium in the Land’s End pluton, Cornwall.

Rare Earth Minerals: The geochemistry and implications of their respective uranium and thorium contents
