Siliciclastic sediment volumes of the South-Pyrenean pro-foreland basin: Eocene exhumation and Source to Sink approach. 

<p>The Pyrenean system has been largely studied in its globality from the tectono-sedimentary evolution of the retro and pro-foreland basins (sinks) to the exhumation history of the Axial Zone (sources) constrained by thermochronological studies.&#160; The present estimation of the siliciclastic sediment volumes from the entire South Pyrenean pro-foreland basin completes the recent measurements made from the Aquitanian retro-foreland basin by using the same methodology. A re-evaluated complete budget of the deposited material in the southern foreland basins (South Pyrenean zone, Ebro basin and Valencia gulf) derived exclusively from the Pyrenean domain is proposed for the Early Eocene-Holocene period (56-0 Ma). Measurement of the compacted siliciclastic sediment volume is based on isopach maps (thickness maps) from <em>Lanaja., 1987 </em>for the Ebro and South Pyrenean zone, while volumes of the Valencia gulf were calculated from <em>R. Pellen 2016</em>.</p> <p>The volumes from the Eocene period (56-33.9Ma) will allow comparison of deposited siliciclastic sediments in both northern and southern sinks and the eroded volumes at the scale of the entire orogen (obtained from the interpolation of compiled thermochronological data) in the light of a source to sink approach.</p> <p>References:</p> <p>Lanaja, J.
