Micro-Geochemical Research in Mineral Exploration, Case Study of the Massive Sulfides of the Bathurst Mining Camp, Canada
Geochemical exploration approaches using micro-chemical techniques are being developed in order to better enhance the understanding of mineral-chemical variations of alteration zones, as well as the effective strategies related to high depth drilling. Herein, is a summary presentation of vectoring tools as developed by Laser Ablation Inductively Coupled Plasma Mass spectrometry (LA-ICP-MS), useful for measuring fluid-mobile elements within indicator minerals of alteration haloes, as sited around the massive sulfide deposits of the Bathurst Mining Camp, Canada. Three vectoring tools, namely, white mica, applicable in proximal and distal zones, chlorite, as an effective proximal tool, and pyrite, applicable in both distal and proximal zones, are presented. The fluid-mobile dispersion patterns noticeable within chlorite, white mica, and pyrite, at the deposit scale, prove to display increasing trend with proximity to ore bodies. These approaches can be potentially applied to other VMS deposits and mineralization modes as complementary techniques.
