Dr Steve Barnes is an economic geologist with particular interests in magmatic ore deposits, layered intrusions and Archean volcanism. He has been with CSIRO in Perth since 1985, with a brief interlude in the exploration industry, formerly holding the position of Science Leader. He has published over 180 journal papers and book chapters covering ore deposits and host rocks on six continents. He was the recipient in 2011 of the Gibb-Maitland Medal of the Geological Society of Australia WA Division for services to Western Australian geology.


Abstract

The Norilsk-Talnakh orebodies account for well over a trillion dollars’ worth of metals, 15% of the global resource of sulfide Ni and over half of the world’s annual palladium production. They are by far the most important deposits that are hosted in mafic-parented small intrusions. Many aspects of these spectacular orebodies remain poorly understood, but new observations at a range of scales from microns to kilometres are providing intriguing new insights. This talk summarises some of these new developments and points out some of the remaining gaps in our knowledge. This talk also serves as a trailer for the magmatic sulfide mineral system short course being run by CET and CSIRO-MR next month.
