Léon Dejonghe (Familleureux, Belgium, 18-10-1946) is civil mining engineer (1969) of the Polytechnic Faculty of Mons, geological engineer (1971) of the Free University of Brussels and doctor of science (state doctorate) (1975) of the Pierre & Marie Curie University, Paris, France.
Most of his career was spent at the Geological Survey of Belgium which is presently part of the Royal Belgian Institute of Natural Sciences, Operational Department Earth and Origin of Life.
His main researches are oriented into two directions: metallogenic investigations (Argentina, Belgium, Congo, Iran, Mexico and Vietnam) and geological mapping (Wallonia and Grand-Duchy of Luxembourg). His field of activity concerns the study of Ba, Fe, Pb, Zn, Sb and Au ore deposits as well as the study of sedimentary rocks of the Paleozoic, in particular those of the Lower Devonian, in terms of lithostratigraphy and tectonics.
From 1979 to 2012, he taught metallogeny at the Free University of Brussels, in the Faculty of Science and, at times, in the Faculty of Applied Sciences. Since 1996, he is a member of the Royal Belgian Academy of Overseas Sciences, Class of Technical Sciences, and since 2002, a member of the Royal Academy of Sciences, Letters and Fine Arts of Belgium, Class of Sciences.
