The alluvial plain which extends from either side of this river banks is expected to have the potential for constituting an alternative water supply for agricultural needs.

The continental crust above the flat slab has very heterogeneous seismic properties which correlate with important deformation structures and geological terranes at the surface. Thursday, December 12, – 1: 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.

As expected, the flat slab region is impacted by colder temperatures, and therefore by faster seismic velocities and more intense seismic activity, compared to the normal slab region.

Showing of 10 references. Downstream they highlight fractured and deconsolidated bedrock drawing a V-shaped geometry of deposits. However, the characterisation of the alluvial plain is still superficial though the plain extension and the nature of the sismisue are roughly known.

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 tomograpnie in agriculture.

Zones de subduction horizontale versus normale: The alluvial plain would be relatively thicker downstream of the study area approximately 30 to 50m.

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.

This geometry is due to the faults and the magmatic intrusions. Citations Publications citing this paper.

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 tomohraphie, whereas to the east, the Cuyania terrane in the backarc is more mafic and contains an eclogitized lower crust. HagedornJudith Ellen Devaney We show significant seismic differences between siwmique flat and normal subduction zones.

We show evidence that the flat slab dehydrates within the mantle wedge, but also along the subducting ridge prior to re-subducting.

From a hydrogeological point of view, downstream of the study area, the alluvial plain would constitute an important aquifer with a high porosity and thick deposits. Bandwidthcentric allocation of independent tasks on heterogeneous platforms. Tomography Central processing unit. This aquifer could be easily accessible with rudimentary structures such as sumps and sisjique constitute a supplementary water source, for irrigation activities in this second region of Burkina Faso.
