Research theme

The 3.09 to 2.97 Ga Murchison Greenstone Belt (MGB) represents one of a number of Archaean volcano-sedimentary belts within the Kaapvaal Craton, South Africa. The MGB is well known for its numerous precious and base metal deposits, including Sb and Au mineralization along a central structural lineament, the Antimony Line (AL). The AL hosts a set of Archean Sb-Au-As-Hg deposits, located in a quartz-carbonate altered listvenite, with a complex deformation history. My study will attempt to provide a geochemical perspective on the Sb-As-Au-Hg mineralization, to examine what caused the mobilization, deposition and remobilization of the Sb in the AL.
