This analysis combines remote sensing, geophysics, petrography and geochemistry, in order to determine the major characteristics of the mafic formations in the said area, and above all to participate in the detailed mapping of all the Ivorian terrains. The mafic formations encountered in this region are essentially metatonalites to metadiorites, amphibolites, amphibole bearing pyroxenites and porphyry basalts. Chemical analysis indicates that these mafic formations are tonalitic to monzonitic. They are thought to have derived from mantle depleted magmas.展开更多
