The tropical cratonic geosystem encompasses non-orogenic continental domains of the
tropical belt that developed and preserved Cenozoic lateritic regolith mantles (ie, the …

Mountain areas are recognized centres of endemism and diversity on account of their
isolation and altitudinal diversity. In tropical regions, mountain tops usually stand as islands …

A simple geochemical balance of lateritization processes governing the development of
several tens of meters of weathering profiles overlain by ferricretes is estimated on the basis …

This study focuses on the dating of millimetric pisoliths from ferruginous duricrusts located in
central Amazonia (Brazil), by coupling detailed mineralogy and two relevant dating …

Abstract The Congo Cuvette (or Basin) is a large depression with an average elevation of
350 m, surrounded by topographic highs: the Central African Atlantic Swell (west), the …

The electrical properties of several tens of metres of lateritic weathering mantle were
investigated by using electrical resistivity tomography (ERT) in two basement areas of …

Abstract The Espinhaço Range is the scene of a long history of exposure to chemical
weathering and erosion processes since the Cretaceous. As a result, ferruginous duricrusts …

In southeastern Central African Republic the lateritic weathering mantles are capped by 2 to
5 m thick ferricretes, which previously formed under a seasonal tropical climate. The actual …

Most geochemical studies of laterite formation have been based on detailed examinations of
a small number of hopefully “representative” profiles. Due to spatial variability in bedrock …

Bauxites and Fe laterites were formed on Neogene volcanics from Fongo-Tongo region in
the highlands of western Cameroon, and are distributed on plateaus, slopes and downslope …
