Birimian Wikipedia

The Birimian rocks are major sources of gold and diamonds that extend through Ghana, Côte d'Ivoire, Guinea, Mali and Burkina Faso.They are named after the Birim River, one of the main tributaries of the Pra River in Ghana and the country's most important diamond-producing area. Ghana and Mali are the second and third largest producers of gold in Africa, respectively.get price

Geological and structural interpretation of the Konongo

The rocks of the area are variable grained, sheared, metamorphosed quartzite containing a constant level of mafic and carbonaceous minerals, presumably derived from syngenetic volcanic activity. Metamorphic grade of the Birimian rocks is that of the greenschist facies (Adjovu, 2006), with local amphibolite facies aureoles around granitoid plutons.get price

Interpretation of Geological Structures Hosting Potential

Historic test work indicates that gold mineralization in Konongo is hosted in disseminated sulphide, quartz veins and weathered metasediment rock (Oberthür et al., 1994). These mineral deposits are structurally controlled and formed during the Eburnean tectono- thermal episode (Griffis et al., 2002).get price
