International Exchange Lecturer (2015)
Andreas Audétat (SEG 2010 F)
Proposed Talk Titles:
- The Metal Content of Magmatic-Hydrothermal Fluids and Their Relation To Mineralization Potential.
- Vapor versus Brine: Which Fluid Does the Job?
- The Genesis of Climax-type Porphyry Mo Deposits: Insights from Fluid and Melt Inclusions.
- Magmatic Controls on Porphyry Cu (±Au, Mo) Formation.
Andreas obtained his Ph.D. in 1999 from ETH Zürich, where he worked in the group supervised by Chris Heinrich and Detlef Günther and was involved in the development of the LA-ICP-MS technique for analysis of single fluid and melt inclusions. After graduation, he joined a group working under Bob Bodnar at Virginia Tech to conduct a comparative study on the composition of fluid and melt inclusions in barren and mineralized intrusions. Returning to Europe, Andreas began working with Hans Keppler, who introduced him into the field of experimental geochemistry. Since 2007, he has held a position as Senior Scientist at the Bayerisches Geoinstitut, where he conducts both experimental studies and studies on natural samples. While his research on natural samples predominantly revolves around magmatic-hydrothermal ore deposits such as granite-related Sn/W, porphyry Cu, and porphyry Mo deposits, the experimental work covers a broad range from physical and chemical properties of subduction-zone fluids over the calibration of thermobarometers for silicic magmas to studies that directly relate to magmatic-hydrothermal ore formation, such as metal solubility in fluids and silicate melts, as well as metal partitioning between fluids, silicate melts, and sulfides. Andreas has authored and co-authored more than 50 scientific articles and book chapters and has received several awards, including the ETH Silver Medal (2000) and the Paul Niggli Medal (2003).
