Geological background and resource potential of gold mineralization in Liberia

More Information
  • In the West African, the Birimian series covering about 36% of Liberia underwent the complex Eburnean orogenic movement, and belongs to one of the main Au-bearing rocks on which the global gold diggers invest.Based on the analysis of the geological background in the West Africa and especially Liberia, a new division of geological units in Liberia was established, and 33 important gold occurrences in the Birimian series were sorted out.The distribution of these gold occurrences is closely related to the metamorphosed volcano-sedimentary rocks (greenstone) of Birimian series and regional shear zone.Based on the comprehensive analysis of the 266 gold mineralized occurrences and geochemical anomalies of Au, Ag, Hg and Cu, eight favorable gold metallogenic belts were delineated in Liberia, namely Bea-Kpo, Dugbe, Cestos, Bautle-Zua-Pifgi, Bong-Toto-Nimba, Dube, Juazhon and Todi.These gold metallogenic belts show a good potential for gold mineralization, and some suggestions were put forward for the prospecting of some gold prospects.
