It is composed of ancient continental sedimentary formations, probably constituted of shale, sand, marl, and arkose. These sedimentary deposits have undergone weak regional metamorphism which permitted the transformation of schist to seritoschists, chloritoschists, graphitic schists, sandy schists, and quartzites, to coarse grained conglomeratic quartzites, to quartzite of medium grained, fine-grained quartzites and to differentiate the phyllitic and siliceous facies.
A cyclic change in the fluvial deposition of sandstones (arkose) to a lacustrine shale environment (Figure 2) may have played a vital role in the formation of some SSDS found in the study area.
