This paper is a contribution to the understanding of surface dynamics of tropical shields over
geological timescales. Emphasis is put on the fundamental and applied implications of …

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

Chemical weathering and mechanical erosion are first‐order processes of long‐term tropical
morphogenesis, which is still poorly deciphered for lack of time constraints. We address this …

Abstract (U–Th)/He geochronology of authigenic goethite cements from the Lynn Peak
channel iron deposit (CID), Hamersley Province, Western Australia, reveals a history of …

Classical geomorphological models identify regional erosion surfaces and raise
hypotheses, currently abandoned but largely untested, about the cumulative effects of …

Quantifying long‐term erosion of tropical shields is crucial to constraining the role of lateritic
regolith covers as prominent sinks and sources of CO2 and sediments in the context of long …

Abstract (U-Th)/He geochronology of two weathered plateaus in the Carajás Mountains,
Pará, Brazil, reveals a history of weathering spanning from ca. 80 Ma to the present for this …

In-situ weathered bedrock, saprolite, is locally found in Scandinavia, where it is commonly
thought to represent pre-Pleistocene weathering possibly associated with landscape …

The southeastern part of the Democratic Republic of the Congo locally hosts Proterozoic
manganese deposits. The deposits of Kisenge-Kamata are the most significant, but …

Abstract (U‐Th)/He geochronology and cosmogenic 3He in iron oxides reveal mineral
precipitation ages as old as 55 Ma and exposure ages greater than 5 Ma for canga …
