Contribution to the Numerical Geological Mapping of the Paleocene in the Western Part of Thiès (Senegal)

Abstract

The locality of Thiès has significant mining and hydrogeological resources that are of major economic interest and necessitates a sustainable management. Most of these resources are contained in the Paleocene. For a better assessment of Paleocene, we elaborated a spatial model using available seismic lines, oil and hydraulic drills. The data were integrated using interpolation, mainly natural neighbor method. The obtained model should make it possible to understand the variation of the lithostratigraphic parameters of the Paleocene. The extraction from the model of the upper and the lower limits showed that the Paleocene is shallow and is outcropping to subout-cropping in the area of Thiès. The model was validated using previously available geological map. Also, a crosscorrelation of the predicted and the observed data showed that the model is accurate.

Stratigraphy of the MSGBC Basin in the Western Part of Thies by Pixelation and Website Simulation (Senegal, West Africa)

“…The top contains marly past with rare echinid debris and a rich microfauna. At the base, the limestone is marly and sandstone, the microfauna poorly preserved [19], and the Maastrichtian and Paleocene are outcropping to sub-sharp in the western part of the Thiès region [5] and [20].…”

Cartography of Landslide Susceptibility around the Dias Horst and Thies Cliff-Senegal

“…The Thies region is rich in mineral and hydrogeological resources that contribute to the economic development of the country and require good management [1]. It is an important sector because it contains the nature reserves of Poponguine and Bandia, the Pout forest, and large holdings of calcareous aggregates, laterites, phosphates and attapulgites.…”
