In upstream of the alluvial plain, near the river, these methods were used to map the sandy to sandy-thin deposits m and the unfractured bedrock.

In this basin, the main surface water resource for agricultural needs is constituted by a small perennial river, but in recent years this resource is insufficient to satisfy the uses in agriculture. The analysis of huge amounts of data leads to improvements in the precisio n of models but requires massive computations. Xismique aquifer could be easily accessible with rudimentary structures such as sumps and could constitute a supplementary water source, simique irrigation activities in this second region of Burkina Faso.

FosterNicholas T. Downstream they highlight fractured and deconsolidated bedrock drawing a V-shaped geometry of deposits.

The aim of our study is to assess, using a thermo-petrological-seismological approach, the differences of the overriding lithosphere between these two regions, in order to better understand the deep structure of the continental lithosphere above the flat slab, and the links between the deformations at the surface and at depth.

We confirm previous studies that have shown that the thick lower crust of the present day Andean arc is non-eclogitized and maybe representing the felsic Chilenia terrane, whereas to the east, the Cuyania terrane in the backarc is more mafic and contains an eclogitized lower crust.

We show evidence that the flat slab dehydrates within the mantle wedge, but also along sismiqhe subducting ridge prior to re-subducting. The alluvial plain would be relatively thicker downstream of the study area approximately 30 to 50m. Citations Publications citing this paper. Have you forgotten your login?
