Zoukougbeu is a department located in the center-west of Ivory Coast which contains geological formations with gold mineralization highlighted by Tietto Minerals mining company during its mapping and drilling campaigns. The general objective of this study is to determine the petrographic characteristics of these formations and the associated gold mineralization. Thus, data acquisition consisted of collecting rock samples in the field from mapping and core drilling, followed by the macroscopic identification of these samples and then the making of thin sections for their microscopic characterization. Petrographic analysis reveals that these geological formations globally oriented NNE-SSW (Eburnean direction) consist of gneiss associated with plutonic intrusives (granodiorites, diorites, granites) deformed and mineralized in syngenetic gold bearing disseminated sulfides. These formations are crossed by faults and of quartz-albite-calcite veins (containing epigenetic gold bearing sulfides) trending NW-SE and E-W. All these rocks are crossed by unmineralized pegmatite veins trending E-W. The mineralization is mainly formed of pyrite and secondarily chalcopyrite, pyrrhotite and native gold. Zoukougbeu rocks are affected by regional metamorphism of greenschist facies accompanied by hydrothermal alteration (pervasive and fissural) which have contributed to the concentration of mineralization like other Birimian gold occurrences in Ivory Coast and Africa. These geological formations are topped by a thick regolith profile due to supergene weathering.
