The Dialafara area is part of the highly endowed kédougou-kéniéba Inlier (kkI), West-m.lian 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 m.p of the Dialafara area. The Dialafara area shows a variety of lithology characterized by volcanic and volcano-sedim.ntary units, m.tasedim.nts and plutonic intrusion. These lithologies were affected by a com.lex superposition of structures of unequal im.ortance defining three deform.tion phases (DD1 to DD3) under ductile to brittle regim.s. These features perm.t to portray a new litho-structural m.p, which shows that the Dialafara area presents a m.re com.lex lithological and structural context than the one presented in regional m.p 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.
