Dr. Richard J. Goldfarb was a research geologist with the Minerals Program of the U.S. Geological Survey for 36 years. He has conducted studies on the distribution of gold deposits throughout the world, compiling comprehensive global descriptions of their spatial-temporal setting, evaluating their ore controlling factors and how best to successfully explore for new resources. His research has been focused on global metallogeny, geology of ore deposits in the North American Cordillera with emphasis on orogenic gold, distribution and geology of lode gold deposits in Asia, and geochemical applications to the understanding of ore genesis. Rich has senior authored and co-authored more than 250 papers on mineral resources, with many recognized as the authoritative research on gold in metamorphic terranes and on aspects of regional metallogeny. He has served as President of the Society of Economic Geologists (SEG), Vice President of the International Association for Gondwana Research, and Chief Editor of Mineralium Deposita. Rich has been awarded the Silver and Marsden Medals from SEG, and was presented with the Kutina-Smirnov Medal for outstanding contributions in the field of economic geology from the International Association for the Genesis of Ore Deposits (IAGOD). During the past two years, he has co-edited the SEG Special Publications on Mineral Deposits of China and on Geology of Major Gold Deposits and Districts of the World. Presently, Rich is a research professor at Colorado School of Mines and China University of Geosciences Beijing, as well as an independent consultant to the exploration and mining industry.
