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

The Rio Capim kaolin, one of the largest kaolin reserves in the world currently under exploration, is typified by a lower and an upper unit represented of a soft, well-structured kaolin and a semi-flint kaolin, respectively, the latter term been appl

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
