"Giant Impacts and the Formation of Ore Deposits"
Some of the largest impact sites known on Earth overlap in space with exceptional concentrations of ore deposits. This has led to speculations on a potential addition of extraterrestrial metal compounds to the Earth’s crust on an economic scale. Using the three largest impact structures as reference, the likely controls of large impacts on metallogeny will be discussed, and it will be shown that metal endowment is strongly controlled by the regional geological make-up of the crust prior to impact.
Hartwig E. Frimmel, who obtained his PhD in geology at the University of Vienna, is Professor and Chair of Geodynamics and Geomaterials Research at the University of Würzburg, Germany. He is also associated with the University of Cape Town where he had previously climbed the academic ladder from lecturer to associate professor. He was leader of the Earth Science subprogram within the South African National Antarctic Program, member of the Geoscience Scientific Standing Committee of the Scientific Committee on Antarctic Research (SCAR), former president of the Society for Geology Applied to Mineral Deposits (SGA), and director of Lithoscope consultancy. He has served on several editorial boards (incl. Mineralium Deposita for the past 23 years), on the International Commission on Stratigraphy, as assessor for numerous national research funding and government agencies, and as consultant to mining/exploration companies as well as government bodies. His research interests developed over more than three decades from metamorphic geology and fluid-rock interaction to metallogenesis and economic geology. A special focus has been the study of sediment-hosted base metal and gold deposits, especially those of the Witwatersrand-type. His research output includes more than 200 articles and book chapters as well as three books.
