The methodology developed is focused on the one hand on the gravimetric geophysical method and on the other hand, on petro-structural studies. The geophysical results highlighted two gravimetric facies characterized respectively by high density (¦¤Bg > 121 mGal) and low density (¦¤Bg < 114 mGal) anomalies. From a lithological point of view, the denser domains are made up of intrusive rocks dominated by granodiorites and tonalites cutting low density facies composed of Tarkwaian formations (polygenic conglomerates and arkosic sandstones) and volcanics (tuffs and cinerites). Structurally, these different lithological groups are affected by brittle (fractures, faults, strike-slip) and ductile (folds, schistosities and mineral lineations) deformations. These structures are mainly oriented NNW-SSW, WNW-ESE and NE-SW. The description of the sulphide minerals reveals a style of gold mineralization of the Tarkwaian formations. %K Gravimetric Method %K Petro-Structural Study %K Tarkwa& %K #239 %K en %K Gontougo Region %K C& %K #244 %K te d¡¯Ivoire %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=129268
