Cerium anomalies in lateritic profiles
Jean-Jacques Braun,Maurice Pagel,Jean-Pierre Muller,Paul Bilong,Annie Michard,Bernard Guillet +5 more
TL;DR: In this article, the geochemistry and mineralogy have been studied in four lateritic profiles, one derived from a syenite (Akongo, SW Cameroon), the others being developed on a gneissic basement and located along a soil toposequence (Goyoum, E Cameroon).

Chemical processes affecting the mobility of major, minor and trace elements during weathering of granitic rocks
TL;DR: In this article, the behaviour of 38 major and trace elements as well as changes in the mineralogy have been examined in 10 weathering profiles developing on some Portuguese granitic rocks, where element mobilities are calculated from geochemical data normalized with respect to Ti in the fresh parent rock.

A review on the potentiality of Rare Earth Elements to trace pedogenetic processes
C. Laveuf,Sophie Cornu +1 more
TL;DR: In this article, the authors consider the use of REEs to trace pedogenetic processes, in order to quantify the respective contribution of successive processes on pedogenesis, and conclude that REEs, much more than other trace elements, can interestingly trace the considered processes that are encountered in a large diversity of non-polluted soils arising from diverse parent materials.

Solid/liquid ree fractionation in the lateritic system of goyoum, east cameroon: the implication for the present dynamics of the soil covers of the humid tropical regions
Jean-Jacques Braun,Jérôme Viers,Bernard Dupré,Mireille Polvé,Jules Rémy Ndam,Jean-Pierre Muller +5 more
TL;DR: In this article, the authors investigated the weathering geochemistry and mineralogy in a lateritic soil cover in relation to the close hydrographical system at Goyoum (East Cameroon).

Geochemistry of mineralization with exchangeable REY in the weathering crusts of granitic rocks in South China
Zhiwei Bao,Zhen-Hua Zhao +1 more
TL;DR: In this article, the authors show that heavy rare earth elements (HREE) and yttrium (MEX-REY) mineralization occurs in weathering profiles of parent rocks ranging in composition from granite to acidic volcanic rocks and lamprophyre.
