The latter includes medium grained biotite and hornblende-biotite gneisses. Minor ferruginous quartzite and amphibolite layers occur within hornblende-biotite gneisses. The above formations cover the project area from the start to nearly the Sudan Border. Ultimately the formations are replaced by alluvial and lacustrine deposits as one reaches the flat terrain.
