ABSTRACT: Magnetic
susceptibility data from marine rocks can be used for global correlation due to
synchronous variations in global erosion. This work, aims to show that, the
magnetic susceptibility signature which exists in the cretaceous sediments of
the Babouri-Figuil basin, resides mainly in the detrital constituents.
Variations of amplitudes are observed, which can be useful for regional correlation.This amplitude
variation results in the transgressive and regressive movements that give way
to a fluctuation of detrital deposits because of erosion. Considering the
sedimentological study, carried out, different microfacies have been
identified in the basin, namely, fluvial facies and lake facies that sometimes
contain fossils. The combination of detailed sedimentological analysis and
sequence stratigraphy is based on the modeling of vertical and lateral
variations within the basin. Finally, the interpretation of the magnetic
susceptibility signal suggests that in the detrital domain, this signal is
mainly controlled by environmental parameters such as the agitation of the
water and the rate of sedimentation, as well as diagenesis.
