Bernardo Beate was born in Quito/Ecuador. He studied Geology at Escuela Politécnica Nacional/Quito, where he graduated as Ingeniero Geólogo. After working as geologist for hydropower proyects, he held a UNDP fellowship for the New Zealand diploma course for Energy Technology/Geothermal at Auckland University in 1981. Back in Ecuador, he was actively involved in the exploration of geothermal resources which involved the geological mapping of most of the volcanic highlands of the Ecuadorian Andes. Since 1983 he has held a part time appointment with EPN, lecturing geothermal exploration, volcanology, petrography, and exploration for mineral resources, mainly epithermal systems. He has been working as consulting geologist for the British Geological Survey, studying epithermal systems in Ecuador, as well as for several mining companies. His current subjects of research are regional geology of Ecuador, volcanology, geothermics, and metallogeny.
Massimo Chiaradia was born in Italy and graduated at the University of Padova (Italy). In 1992 he completed a Ph.D. degree at the University of Fribourg (Switzerland) on a late Paleozoic gold-arsenic-tungsten skarn of the Swiss Alps. After a stage at the CSIRO/EM (Sydney, Australia) where he worked on the application of lead isotopes to environmental problems, from 1996 to 2002 he has been technical and scientific responsible of the lead isotope laboratory at the Department of Mineralogy of Geneva (Switzerland). In Geneva he carried out various environmental projects and research on mineralization and magmatism of the Andes, especially those of Ecuador. Presently he is Research Fellow at the School of Earth Sciences, University of Leeds (U.K.) where he runs a radiogenic (U-Pb, Rb-Sr) and stable (Cl) isotope laboratory. His current research activities are focused on radiometric dating of ore deposits (U-Pb on calcite and Rb-Sr on sphalerite of MVT deposits of Peru and Ireland) and on the application of Cl isotopes to trace fluid sources in Fe-oxide-Cu deposits of Peru and Chile. He is a member of the Executive Committee of SGA and of the Editorial Board of Mineralium Deposita.
Arturo Eguez Delgado has been since 1982 professor for geology at the Escuela Politécnica Nacional (EPN) in Quito-Ecuador. In 1986 he obtained a PhD from Pierre et Marie Curie University (Paris VI - France) for his work on the geotectonics and metallogeny of the Western Cordillera of Ecuador. He is a consulting geologist and co-author of the geological, tectono-metallogenic, and seismotectonic national maps of Ecuador. His publications and current subjects of research are Andean regional geology, tectonics, and metallogeny.
Jeffrey W. Hedenquist graduated from Macalester College, St. Paul, and The Johns Hopkins University, Baltimore, and worked for the U.S. Geological Survey on coastal sedimentology and lunar studies. He held a Fulbright Fellowship to New Zealand from 1979, and in 1982 he completed a PhD degree at the University of Auckland on gold mineralization of the Waiotapu geothermal system. Following 10 years with a national institute in New Zealand, where he conducted research on geothermal energy and epithermal ore deposits, a further 10 years was spent with the Geological Survey of Japan studying volcanic discharges and porphyry ore deposits. Since 1999 Dr. Hedenquist has worked from Ottawa as an independent consultant for mining companies as well as national and international agencies. He has conducted field work and training in over 30 countries on hydrothermal ore deposits and related topics. Since 2002 he also held a half-time appointment at the Colorado School of Mines as Research Associate Professor (http://www.mines.edu/academic/geology/). He served as the SEG Vice President for Regional Affairs, 2000-2002.
Lluís Fontboté was born in Barcelona and studied geology at the University of Granada, southern Spain. After a Ph. D in the University of Heidelberg, Germany, he participated in and led several research projects in South America funded by the research councils of the European Community and of Germany. Several works of this time are published in the book "Stratabound ore deposits in the Andes", which he edited with several colleagues in 1990. Since 1990 he is full professor in economic geology at the University of Geneva. He has built up together with Robert Moritz an active group (http://www.unige.ch/sciences/terre/research/Groups/mineral_resources/mineral-resources.php) of research graduate students and postdoctoral fellows working in economic geology. Projects Fontboté has recently finished or is currently carrying out with his students and coworkers, in cooperation with several mining companies, include studies on Cordilleran polymetallic mineralization largely under high sulfidation conditions, Fe-oxide-Cu deposits, orogenic Au deposits, volcanic-hosted massive sulfides, Au skarns, and MVT deposits, as well as on oxidation processes in mine tailings. He has served in the SEG and SGA councils.
Peter D. Lewis is a consulting structural geologist based in Vancouver, Canada. He completed his B.Sc. at Stanford University and his M.Sc. and PhD. at the University of British Columbia. He held a post-doctoral fellowship with the Mineral Deposit Research Unit at UBC from 1991 to 1994. He has also held lecturer positions at the University of British Columbia in structural geology and field geology, and teaches short courses for industry on topics including field mapping, and structural geology of epithermal and mesothermal deposits. Lewis has been an independent consultant to the mineral exploration and mining industry for the last nine years, specializing in structural controls on mineral deposits. He has worked throughout North and South America, Eastern Europe, Southeast Asia, and China. His experience covers a wide range of deposit types, and much of his recent work has been on Latin American epithermal precious metal deposits.

Jeremy Richards is a professor of economic geology at the University of Alberta, Canada. He received B.A. and M.A. degrees from Cambridge University, UK, an M.Sc. from University of Toronto, Canada, and a Ph.D. from the Australian National University. After holding a post-doctorate fellowship at the University of Saskatchewan from 1990 to 1992, he was appointed lecturer at the University of Leicester, UK. Dr. Richards has been with the University of Alberta since 1997. Research interests and activity have focused on the genesis of hydrothermal mineral deposits. Within this field Dr. Richards’ broader interests cover aspects as diverse as regional tectonic and magmatic controls on mineralization, volcanology, and detailed ore depositional mechanisms. He has investigated the formation of various types of ore deposit, including sediment-hosted, vein-type, and porphyry-type copper, and mesothermal and epithermal gold mineralization. In addition to extensive fieldwork (mapping, sampling), he also is familiar with a full range of analytical techniques, including stable and radiogenic isotopes, whole-rock geochemistry, mineralogy, and fluid inclusion microthermometric and compositional analysis. His current research involves the study of regional controls on porphyry copper and polymetallic epithermal mineralization in northern Chile and Argentina. The project aims to characterize events that led to the development and emplacement of Cenozoic porphyry copper magmas through field mapping, geochronology, whole-rock geochemistry, and isotopic studies. In particular, focus has been brought to bear on deep crustal structural controls on magma emplacement, and characterization of such structures has extended my research deeply into the field of volcanology and magma emplacement mechanisms. Jeremy Richard is the SEG International Exchange Lecturer for 2003 (http://www.segweb.org/IEL.html) and has held various offices in SEG and SGA.
