The
Dialafara area is part of the highly endowed Kédougou-Kéniéba Inlier (KKI),
West-Malian gold belt, which corresponds to a Paleoproterozoic window through
the West African Craton (WAC). This study presents, first of all, an
integration of geophysical data interpretation with litho-structural field
reconnaissance and then proposes a new litho-structural map of the Dialafara
area.The
Dialafara area shows a variety of lithology characterized by volcanic and
volcano-sedimentary units, metasediments and plutonic intrusion. These
lithologies were affected by a complex superposition of structures of unequal
importance defining three deformation phases (DD1 to DD3)
under ductile to brittle regimes.These
features permit to portray a new litho-structural map, which shows that the
Dialafara area presents a more complex lithological and structural context than
the one presented in regional map of the KKI. This leads to the evidence that this area could be a potential
site for exploration as it is situated between two world-class gold districts.
