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.
