Benedetto De Vivo, after graduation (1971) from the University of Naples Federico II in Geological Sciences and military service (1972), worked for private companies operating in Italy, Africa, and Central America in the field of ore deposits, geochemical prospecting, environmental geology, and hydrogeology (1973–1977). Later, he was a Researcher at CNR-Roma, Italy (1977–1987), Associate Professor in Applied Geochemistry (1987–2000), and Full Professor in Geochemistry at the University of Napoli Federico II (2000–2017). He was a research fellow at the Colorado School of Mines (1978) and at US Geological Survey, Reston, VA (1982 and 1992); Chairman of the Working Group “Inclusions in Minerals of the International Mineralogical Association; Member of the Editorial Board of GEEA (2004–2007), Minerology and Petrol (1997–2007), American Mineralogist, and Chief Editor of Journal of Geochemical Exploration (2007–2017). His research interests span a wide range of topics including geochemical prospecting, fluid and melt inclusions studies on volcanic and sub-volcanic systems, and environmental geochemistry. He has published about 300 papers (in top international peer-reviewed journals), editing different special volumes (Journal of Volcanology and Geothermal Research, European Journal of Mineralogy, Institution of Mining and Metallurgy, and, Minerology and Petrol), and has authored four text books (in Italian) in geochemical prospecting and environmental geochemistry. He was nominated (2001) as Fellow of the Mineralogical Society of America and appointed as an Adjunct Professor at Virginia Tech, Blacksburg, VA, USA (2006), Nanjing University, China (2016), and Hubei Polytechnic University, Huansgshi, China (2019). He was the recipient of the 2019 Gold Medal Award of the Association of Applied Geochemists for outstanding scientific contributions and achievement in applied geochemistry.
Harvey Belkin is currently a Research Geologist Emeritus for the U.S. Geological Survey, Reston, Virginia. After a career of 45 years, the position of Emeritus allows continued research. After majoring in geology and geochemistry at Franklin and Marshall College and George Washington University, he joined the Branch of Experimental Mineralogy and Geochemistry, USGS. During the early part of his career, he applied the study of aqueous and silicate-melt inclusions to address problems in a wide variety of earth environments, such as ore deposits, radioactive waste disposal, and volcanology. The latter part of this career involved human health issues related to domestic use of coal and other earth materials as well as continued research in different aspects of mineralogy, petrology, geochemistry, and volcanology. The author or co-author of more than 150 peer-reviewed papers, more than 200 presentations, and editor or co-editor more than 20 books and abstract volumes, Harvey Belkin continues research in a wide variety of geologic problems.
