Platinum Group Elements (PGE) geochemistry of komatiites and boninites from Dharwar Craton, India: Implications for mantle melting processes
High MgO volcanic rocks having elevated concentrations of Ni and Cr are potential hosts for
platinum group elements (PGE) owing to their primitive mantle origin and eruption at high
temperatures. Though their higher PGE abundance is economically significant in mineral
exploration studies, their lower concentrations are also valuable geochemical tools to
evaluate petrogenetic processes. In this paper an attempt has been made to evaluate the
PGE geochemistry of high MgO volcanic rocks from two greenstone belts of western and …
