Geochemical Processes in Tropical Landscapes: Role of the Soil Covers,cart and Michel (1965), soil science relates to geomorphology as geomorphology does to structural geology. Geomorphological evolution constitutes a framework to soil formation and evolution. Soils rarely develop directly in situ at the expense of a parent rock. Much more frequent is the formation of

The Lateritic Nickel-Ore Deposits,in silicated Fe-Mg minerals by octahedral substitution with Fe. ions. Thus, the mean mineral/ matrix partition coefficient of Ni is 14.0,5.0 and 2.6 for basaltic whole rocks, for olivine, and orthopyroxene and clinopyroxene, respectively. The high Ni contents in olivine (3000–4500 ppm), spinel (3000

Continental Silicifications: A Review,ion of the Fontainebleau Sands, he cited the Libyan dune fields suggesting that each winter Si went into solution in the soils and «thickened» by desiccation during the summer. Later, Gosselet (1888) created the expression «atmospheric metamorphism» to explain the Eocene quartzites of the Paris Basi

Clay Minerals, Paleoweathering, Paleolandscapes and Climatic Sequences: The Paleogene Continental Ds (Millot, 1949), he tried to understand the mechanisms producing weathered landscapes. He worked in collaboration with geologists, geographers and geochemists, attempting to reconstruct the different components of the landscape. He was interested in every type of weathering and investigated the reg
