Platinum Group Element Geochemistry of Andesite Intrusions of the Kelian Region, East Kalimantan, Indonesia: Implications of Gold Depletion in the Intrusions Associated with the Kelian Gold Deposit

Setiabudi, Bambang; Campbell, Ian; Martin, Candace; Allen, Charlotte M


Nineteen andesite samples from the Kelian gold mine and two adjacent prospects, Magerang-Imang and Nakan, in East Kalimantan, have been analyzed for Cu, Re, Au, and the platinum group elements (PGE). The aim of the study was to use variations in PGE concentrations to test whether the chalcophile elements became enriched or depleted with fractionation in the igneous suites associated with the Kelian deposit. When the data are plotted on mantle-normalized chalcophile element diagrams, the...[Show more]
