A geomorphological, geological and metallogenic study of the Adamaoua region

This book is a summary of the Master's thesis completed in 2013, which forms part of the ongoing geomorphological, geological and metallogenic study of the Adamaoua region. The specific objectives are: to carry out a geomorphological characterisation of the Ngaoundal and Ngaoundéré cliff sites; to carry out a mineralogical and petrographic characterisation of these sites; to carry out a metallogenic characterisation of the Ngaoundal site; and to estimate the ore tonnage of the Ngaoundal deposit. From a geomorphological perspective, two main units can be distinguished on the Ngaoundéré cliff and three at Ngaoundal. Petrographic analyses revealed, on the Ngaoundéré cliff, biotite gneisses with a granolepidoblastic texture and biotite granites with a porphyroid-grained texture; whilst at Ngaoundal, the olivine basalt exhibits a porphyritic microlitic texture. The various facies encountered at Ngaoundal are nodular, massive, vacuolar, pisolitic and pseudonodular. A digital elevation model was utilised at these sites to improve the quality of the morphological data already available for them.
