Thomas Monecke is an economic geologist who specializes in the formation of base and precious metal deposits in modern and ancient volcanic arcs. He has more than 25 years experience in geological research and mineral exploration and has authored or co-authored approximately 80 journal papers, book chapters, government publications, and field guides during that period. Thomas graduated from the University of Freiberg, Germany, with a M.Sc. in 1996. He obtained his Ph.D. from the same university with his doctoral thesis focusing on the anatomy of a volcanic-hosted massive sulfide deposit in northern Australia. Between 2002 and 2008, Thomas conducted post-doctoral research at the Institute of Marine Sciences in Kiel, Germany, the University of Ottawa, and the Geological Survey of Canada on modern and ancient gold-rich volcanic-hydrothermal systems. In 2006, Thomas received the Waldemar Lindgren Award of the Society of Economic Geologists. He joined the Colorado School of Mines in 2008 where he currently teaches economic geology. Thomas runs a large research group and supervises graduate student working on a diverse range of hydrothermal ore deposits around the world.
