Abstract

Development of techniques that spatially represent and rank geological features controlling MagmaticNi-Cu-PGE, Volcanogenic Massive Sulfide Cu-Zn-Pb-Ag(-Au), and Orogenic Au mineral system prospectivity in Archean greenstone belts near Timmins and Dryden, Ontario. The study summarizes current geological knowledge, applies statistical methods to enhance knowledge using geochemistry, and explores various techniques to map structural complexity, pre-deformation fluid path distances, rheological and chemical contrast, magmatic geochemistry, and hydrothermal alteration. Random forests importance ranking identifies factors controlling mineralization and explain contrasting orogenic Au endowment in the studied greenstone belts. Multi-disciplinary data and methods are needed to improve existing geological understanding and exploration strategy.
