After 2 years active service in an armored artillery battalion with the German Army (his rank when resigning from the armed forces in 2006 was colonel of the German Armed Forces Reserve) he began studying geology in 1971 at Würzburg University (minor: geography, mineralogy) followed by economic geology at the Technical University at Aachen. He received his M.Sc. degree in geology in 1975 (stratigraphy and paleo‐environmental studies). In 1978 he was graduated from Erlangen University on pyritiferous Pb‐Cu‐Zn deposits in Tuscany, Italy (mineralogy, economic geology). Subsequently, he entered upon a one‐year research work at the department of soil sciences and soil geography of Bayreuth University (geophysical deep sounding, study of duricrusts). Since 1979 he has been with the Federal Institute for Geosciences and Natural Resources (BGR), Hannover ( geophysics/ radiometric age dating). He was mainly involved in the study of U concentration processes, a joint research projects in close cooperation with international agencies and exploration companies in France, Italy and Australia. From 1986 through 1991 he was the staff member of the project management group of the "Continental Deep Drilling Program of the F.R. Germany, being responsible for economic geology, mineralogy and geochemistry. In 1982 he became lecturer for applied geology at Mainz University, where he obtained his Dr. habil. degree in 1985 after submission of his thesis entitled "Ore Mineralization at the Western Edge of the Bohemian Massif" (assistant professor). In 1991 he was appointed associated professor at Hannover University, in 2008 honorary professor at Mainz University and in 2010 profesor invitado de la Universidad Nacional del Sur ‐ Bahia Blanca, Argentine and he was awarded an honory doctor (doctorate honoris causa). He gives lectures in economic geology (metallic and non‐metallic deposits), applied sedimentology and lecture courses in petrographic microscopy and is mentoring young colleagues (Ms. students) during more than 35 years. Aside of his regular teaching posts he was/is involved in teaching at universities in Bangkok (Thailand), Cottbus (Germany), Bogota (Colombia), Doha (Qatar), Vilnius (Lithuania), Ulan Bataar (Mongolia), Zomba, Malawi, Tashkent (Uzbekistan), Riga (Latvia), Muscat (Oman), Amman (Jordan), Tunis (Tunisia), Hanoi (Vietnam), Athens (Greece), Bahia Blanca (Argentina), Izmir (Turkey), Caracas (Venezuela), Brno (Czech Republic), Miskolc (Hungary) and Iasi (Romania). In BGR he was senior research scientist in “Geophysical exploration and technical mineralogy (main interest: chemistry and mineralogy of ancient and modern depositional systems related to fossil fuel, metallic and non‐metallic deposits). His work has led to more than 330 publications, more than 100 abstracts, several open file reports and he is holding a patent for spectroscopic on-site determination of clay minerals in aggregates. His scientific work led also to the discovery of a smectite‐bearing clay deposit at the edge of the Gobi Desert, Mongolia, helped delineating a gypsum‐celestite deposit in the desert on the Qatar Peninsula, and contributed to the finds of oil in the Permo‐Carboniferous basins in SE Germany. Only recently he was involved in the discovery of Sc‐bearing aplite and lazulite pegmatite occurrences. He is also associate editor of "Ore Geology Reviews" and " The Journal of African Earth Sciences". Furthermore he conducts studies in the field of archeometallurgy, mining history and has written his second book on the history of aerial warfare. By the end of May 2014, he retired from BGR, working as self-employed author , lecturer and free-lance geologist in environmental and economic geology.
