Abstract
This study is a contribution of indirect methods to classical geological and structural mapping in a region where outcrops are scarce. The East of the mountainous "Eastern Baoulé " offers a suitable framework for operating an MNA for the purpose of structural mapping. The MNA false image was produced from the extraction of contour lines, through creation and rasterisation of a file of elevation database. That false raw image was the subject of image enhancement using the techniques of illumination at 45 ° along the parallel directions NE and orthogonal NO to the mountain range of Bongouanou. It appears that the lineaments obtained are regional in scope and are only located in a mountainous terrain. The majority N30 ° and N130 ° lineaments have been identified in outcrop as foliation and lineation crenulation hence their abundance in a schistose context. However, the relative positions of these lineaments in staggered blocks suggest a sinister fracturing in directions N130 ° and N160 ° in a structural context in compression as is the case in the Proterozoic in Côte d'Ivoire.
