Contents

This TGI4 Ni-PGE Project establishes typical element associations and behaviours for the paragenetically different hydrothermal assemblages, especially those that characterize the mineralizing fluids associated with the low-sulphide, high-precious metal mineralization (LSHPM) in the footwall to the Sudbury Igneous Complex. Also included with this report is the data release of geochemical databases of (a) laser ablation ICP-MS mineral chemistry of epidote, allanite, amphibole, and titanite and (b) whole-rock geochemistry of least-altered host-rock types.
