Outline• Why aqueous geochemistry in mineral exploration?• Field analyses - importance of pH and Eh• Major species• Trace metals and metalloids• Stable isotopes• Radiogenic isotopes• Insights gained from water chemistry• Seawater exploration for SMSGNS Science
Utility of groundwater geochemistry• Significant challenge for mineral exploration is to findnew and deeper deposits, particularly in areas whereeither thick cover exists• Where past exploration has already discovered shallowmineralization and exploration must extend to greaterdepth• Groundwater recharges to depth, resulting in greaterlikelihood of interacting with buried mineralizationcompared to surficial geochemical methods, thusproviding a three dimensional perspective• Aqueous geochemistry can provide insights into othersample media and dispersion processes, secondarymineral formationGNS Science
