This work deals with the petrographic, cartographic and geochemical study of the Tondo area or grouping. Our study area was affected by the Kibariene orogeny of the Burundian group which is one of the geological periods of Central Africa, characterized by several metamorphisms, which affected the study area. Thus, we have described outcrops that in general comprise metamorphic rocks. We had to describe about fifty outcrops along the field minute and after the macroscopic analysis of the samples taken on the field and the microscopic analysis made in the laboratory, we were able to find that th...
This work deals with the petrographic, cartographic and geochemical study of the Tondo area or grouping. Our study area was affected by the Kibariene orogeny of the Burundian group which is one of the geological periods of Central Africa, characterized by several metamorphisms, which affected the study area. Thus, we have described outcrops that in general comprise metamorphic rocks. We had to describe about fifty outcrops along the field minute and after the macroscopic analysis of the samples taken on the field and the microscopic analysis made in the laboratory, we were able to find that the rocks outcropping in these sectors are largely the result of a regional metamorphism having affected these regions which are part of the Kibaian formations.The Schist. Quartzites, Gneiss are also part of these sectors. geochemical trace elements are : Co, Cu, Zn, Mo, Sb, Zr, Ni, Cr, V, As, Se, Sr, Ag, Cd, Sn, W, Hg, Pb, Bi, Th, U, Au, Nb and Ta. Gold and Tin are the main minerals disseminated in the schist.
