Soil Mineralogy
Focuses on the solid inorganic phases controlling the physico-chemical processes in soils and sediments. Definition of activities, meetings and a discussion list.

European Network on Lateritic Weathering and Global Environment
EUROLAT is an information network for surface processes involving chemical weathering. Lateritic weathering and tropical environments involve all geophysical and geochemical processes occurring at the interfaces atmosphere - biosphere - hydrosphere - lithosphere and include surficial mineral deposits, geochemical prospection, soil and clay mineral formation, land erosion, hydrology and paleoclimatology.
