International audience; The present study is a contribution to the understanding of continental-scale source-to-sink sedimentary systems over geological time scales. The northern half of South America is taken as a case study to explore the relations

Many European uplands have remained topographic highs for protracted periods of weathering during the Mesozoic and Cenozoic. The long-term elevation position as low relief of these massifs acted as a source for adjacent sedimentary basins, their weat

The Palaeogene represents the last “greenhouse” period characterized by high atmospheric CO2 concentrations and warm surface temperatures. This long-term climatic state was punctuated by several transient hyperthermal events. These events are rec

Laterites are developing under intense chemical weathering and low physical erosion rates. Despite their large extension at the Earth’s surface, there is still a lack of time constraints for their formation, evolution and relation with climatic cha
