    Alan J. Anderson, Richard Wirth, Rainer Thomas


    Alan J. Anderson is a professor in the Department of Earth Sciences at St. Francis Xavier University in Antigonish, Nova Scotia, where he has been a faculty member since 1989. Dr. Anderson received his BSc in geology at the University of Windsor, his MSc at the University of Manitoba, and his PhD at Queen's University in Kingston, Ontario. He spent two years as a postdoctoral fellow at the fluids research laboratory at Virginia Tech and was a guest scientist at the German Research Centre for Geosciences, Potsdam, in 2003. Dr. Anderson's research focuses on the chemical and physical properties of solvothermal fluids in the Earth's crust and their role in geochemical processes such as mass transfer and ore formation. Part of his research involves detailed characterization of minerals and fluid inclusions and the application of various spectroscopic techniques for in situ analysis of experimental fluid systems at extreme conditions in diamond anvil cells. Dr. Anderson is also involved in field-based studies of granite-related ore deposits and granitic pegmatites in North America, Africa, and Australia.

    Richard Wirth is supervisor of the electron microscopy (FIB/TEM) laboratory at GFZ German Research Centre for Geosciences, Potsdam, Germany. Dr. Wirth received his PhD in 1978 at the University Wurzburg, Germany. He spent 3 years as a postdoctoral fellow at the Institute of Metals Physics at the University Saarbruecken, followed by research scientist positions at the University Cologne, the Institute of Advances Materials, Saarbruecken, and Ruhr-University-Bochum. In 1994 he established the TEM laboratory at the GFZ Potsdam, which he has continued to develop by incorporating modern technologies such as the focused ion beam (FIB). His main research areas are micro- and nano-inclusions in diamond, the structure and behavior of grain boundaries, and amorphous intergranular layers along interfaces in mantle xenoliths. He is cooperating with groups in Austria, Brazil, Canada, France, Israel, Russia, Ukraine, and USA. Dr. Wirth was awarded the GFZ Research Award in 2003 and in 2005 was granted the W. F. James Chair in Science at St. Francis Xavier University in Antigonish, Nova Scotia, Canada.

    Rainer Thomas received his master's degree in mineralogy, his PhD., and his Habilitation at Freiberg University of Mining and Technology. He worked in the semiconductor industry from 1969 to 1988, where he carried out research on crystal growth by chemical transport reactions, developed polishing technologies for silicon wafers, and performed X-ray studies on crystals using single- and double-crystal topographic techniques and multiple-diffraction measurements. He was head of the X-ray fine structure laboratory for 15 years while in the semiconductor industry. Dr. Thomas began work as a research scientist in 1988 at the Central Institute of Physics of the Earth in Potsdam, and then joined the GeoForschungsZentrum Potsdam in 1992, where he remained until his retirement in 2007. Throughout his career, Dr. Thomas has studied all aspects of fluid and melt inclusions in minerals and has used Raman microspectrometry for the characterization of inclusions and other geomaterials. He is also recognized for developing a Raman spectroscopic method for measuring trace to major amounts of water in glasses and melt inclusions. A main focus of his research since the beginning of his inclusion work in 1968 has been the genesis of pegmatites using melt and fluid inclusions.
