Georges Stoops contributed substantially to the understanding of the genesis of arid and tropical soils, and to the development of concepts and terminology for the description of soil thin sections. His outstanding research activities in an international context, contributed considerably to the development of soil micromorphology, while his enthusiastic teaching in Ghent and elsewhere promoted the use of soil micromorphology worldwide. His achievements have been honoured for instance by the Kubiëna Medal of the International Soil Science Society (1992) and the Philippe Duchaufour Medal of the European Geosciences Union (2010).. Dr. Marcelino has many years of research experience in soil micromorphology, especially in the field of tropical soil development, and was guest lecturer at several Intensive Training Courses on Micromorphology organised in various European countries. Dr. Mees has many years of research experience in sediment petrology, soil mineralogy and micromorphology, applied to sediments and soils in arid and semi-arid environments, and later mainly in humid tropical environments, especially in Central Africa.
