In particulargeologists face to the lack of model to be able to better predict the reservoir presence and quality of undrilledbasins. The source-to-Sink studies (“S2S”) on modern or recent systems are of particular interest because theyaim to understand and quantify the link from the source/hinterland area (drainage area, nature of the bedrock,climate and topography) to the sink/basin (slope gradient, shelf size, eustasy and sedimentary process). Theapplication of this S2S approach on ancient sedimentary systems is challenging because of the lack ofconstraints of some controlling factors like the climate, the composition of the source material, the locationand altitude of paleo-reliefs or the extent of the drainage area. Our aim is to explore if there is a way toanticipate the impact of the tectonic /geodynamic and climatic evolution of a hinterland on clasticaccumulations in the basin and their related mineralogical composition in the basin using the same data-setthat can be obtained during an early exploration phase.The Mozambique margin during Meso-and Cenozoic times is a well-documented S2S system. The ongoingstudies by G. Baby, J-P. Ponte PHD’s respectively on the South African Plateau and MozambiqueMargin provide through times: 1) in the source area, valuable mapping of weathering paleosurfaces that allowto constraint the drainage areas and volume of eroded sediments and synthesis of thermochronology data and2) in the basin, regional seismic interpretations, paleogeographic maps, quantification of deposited sedimentsbased on news biostratigraphical data. Knowledge of climate evolution during the Cretaceous is improved bypalynologic studies from wells done by TOTAL.Here, we present a new project which will focus on the lithological and mineralogical records on cuttingsfrom two old exploration wells. In order to recognize the impact of provenance, climate, diagenesis andtransport processes on sediments mineralogy, we focus on the signature of the sandstones includingpetrographical analysis (E. Garzanti; Milan University), heavy mineral quantification (S. Ando; MilanUniversity) and U/Pb datation on zircon. We will also quantify along the two wells the clay mineralogicalassociation of lutites by XRD analysis. %G English %L insu-01718007 %U https://insu.hal.science/insu-01718007 %~ INSU %~ IFP %~ UNIV-RENNES1 %~ UR2-HB %~ CNRS %~ GR %~ OSUR %~ GIP-BE %~ UR1-HAL %~ UR1-SDLM %~ GR-PPDB %~ UNIV-RENNES2 %~ TEST-UR-CSS %~ UNIV-RENNES %~ INRAE %~ UR1-ENV %~ GR-R %~ TEST3-HALCNRS %~ TEST4-HALCNRS %~ TEST5-HALCNRS
