The Ipixuna Formation (late Cretaceous? early Tertiary) exposed in the Rio Capim area, northern Brazil, was subdivided recently into three stratigraphic units, informally known as the lower soft kaolin, the intermediate kaolin, and the upper, endured

Deuterium ( δ D) and oxygen ( δ 18 O) isotope data from the Rio Capim kaolin, northern Brazil, were combined with optical studies in order to better understand the genesis and evolution of the kaolinites. The results show that δ 18 O values from a

A paleomegafauna site from central Amazonia with exceptional preservation of mastodons and ground sloths allows for the first time a precise age control based on14C analysis, which, together with sedimentological and δ13C isotope data, provided the

Event beds recording Late Cretaceous synsedimentary seismicity occur in the Cameta Subbasin, northern Brazil. The deposits consist of nearly 40 m of kaolinized, fluvio-estuarine deposits. The lower fluvial (tidal-influenced) complex, which carries a
