We review geological evidence on the origin of the modern transcontinental Amazon River,
and the paleogeographic history of riverine connections among the principal sedimentary …

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

The field of (U-Th)/He geochronology and thermochronology has grown enormously over
the past∼ 25 years. The tool is applicable across much of geologic time, new (U-Th)/He …

A transformative advance in Earth science is the development of low‐temperature
thermochronometry to date Earth surface processes or quantify the thermal evolution of …

South America is home to the highest freshwater fish biodiversity on Earth, and the hotspot
of species richness is located in the western Amazon basin. The location of this hotspot is …

The dynamics of tropical weathering through time with the formation and long-term evolution
of laterite associated with climatic and geodynamic forcing is still a poorly explored issue. To …

Under tropical climates, mineral assemblages composing lateritic weathering profiles offer
precious records of past weathering conditions. Silicon (Si) isotope signatures in the clay …

Kaolinite naturally contains radiation-induced electron defects in its structure induced by
ionizing radiations and can be analyzed with electron paramagnetic resonance …

The study of paleofluvial dynamics is crucial to understand the role of rivers as
biogeographic boundaries in Amazonia during the Cenozoic. In central Amazonia, Mesozoic …

Apatite and zircon (U–Th)/He thermochronological data are obtained through a combination
of crystal selection, He content measurement by crystal heating with analysis using noble …
