R. Abstract-the and . Geochemistry, SW Cameroon), the others being developed on a gneissic basement and located along a soil toposequence (Goyoum, E Cameroon) There is a fractionation between LREE and HREE in the lateritic samples during weathering, the weathered residual products being enriched in LREE (l'rom La to Eu) and depleted in HREE (l'rom Gd to Lu); sam pied waters are enriched in HREE in relation to the syenite host-rock. A positive Ce-anomaly has been found systematically at the top of the saprolite, beneath a zone of iron oxide accumulation in the laterite, Ce02, is present as very fine coatings in non-ferruginous clayey domains

R. -. Primary, Specifically, allanite and apatite are transformed into f10rencite and rhabdophane but these phases have no Ce-anomaly. Ali the data are interpreted as the result of the following processes: ( 1) REE leaching in a reducing environ ment) oxidation of Ce J + to Ce 4 + in an oxidizing environ ment. and (3) deposition of cerium as cerianite whereas the other REE remain in solution
