At the invitation of Professor Zhao Peng, J.C. Samama, a dean and mineralogist of the National Institute of Geology and Mineral Resources of Nancy, France, came to our hospital for academic exchange from March 11 to March 18. Professor Samama systematically introduced the following topics under the general heading of “Continental Weathered and Mineral Deposits”: the geochemical definition of continental weathering and its characteristics; geochemical landscapes and deposits; deposits related to the migration of dissolved facies; sediments associated with residual facies Ore deposits; secondary enrichment of copper and nickel sulfide deposits; secondary enrichments of iron and manganese deposits; lateritic nickel deposits; karst-related deposits; silico-conglomerate-type fluorite deposits; bauxite deposits; Weathering and deposits. In addition, he also outlined the secondary enrichment of uranium deposits and the uranium-rich superficial veins.
