Abstract

The petrographic and geochemical data of the granitoids of the central part of the Toumodi-Fettekro sillon (or belt) have allowed to characterize a complex set whose main terms can be summarized as follows: biotite granites, granodiorites, leucogranites and aplitic bodies. These rocks are composed of quartz, plagioclase, biotite, potassium feldspar, with variable hues (leucocrate to mesocrat), structures (medium to coarse grained) and mineralogical proportions (depending on abundance). The geochemical interpretation is based on the systematic search for genetic links between the various terms of this assemblage. Thus, geochemistry has enabled us to distinguish three facies (biotite granites, leucogranite and aplitic granite) that are weakly altered and peraluminous in character (A/CNK > 1) and a fourth (granodiorite) that tends to be metaluminous (A/CNK < 1). The strongly aluminous character of these three facies and the presence of minerals such as muscovite, garnet and tourmaline, as well as the presence of numerous pegmatite veins, suggest a sedimentary origin (S-type granite). The granodiorite, on the other hand, seems to have genetic links with TTG-type protoliths through a partial fusion process.
