It is important to highlight the fact that these highlands correspond roughly with the areas of volcanic rocks and uplifted areas of basement complex rocks.
While in Maru area, they are inter-bedded with massive green phlyllites, feebly developed slaty rocks, flaggy tuffaceous materials and amphibolites. The mandate was to look geoolgy raw materials for steel production.

The major soil types in Nigeria, according to FAO soil taxonomy legends are fluvisols, regosols, gleysols, acrisols, ferrasols, alisols, lixisols, cambisols, luvisols, nitosols, arenosols and vertisols. The Mid-Niger Basin is a shallow trough filled with Cretaceous marine to continental sediments.
There is at present an upsurge of interest in the development of solid mineral resources whose production in the last 30 years has been declining in every case.
On one of exposure, there is down deep weathering. The lithologic composition of the Asu River Group comprises limestones, shales, micacous siltstones, mudstones and clays Offodile, ; Obaje, This is a characteristic species for the late Turonian-early Senonian of the Ivory Coast and was reported from the Coniacian-Campanian of Gabon by Boltenhagen in Archibong, The soil is in fact not sandy.

Initial gravity studies in the Bida Basin put the maximum thickness of the sedimentary successions at about 3. Charnokite Bauchite There is a contact between the porphyritic granite and bauchite. In Lafia, Awe area, the formation can be traced to Makurdi formation, and is thought to be lateral.
Furthermore, the occurrences in form of springs, ponds and dug-holes are rather closely associated with the fracture systems within the trough. This is also true if material for comparison of complex lithologic sequences is only present in deep well cores that are not readily available for study.
It is not clear whether this feature could have restricted the movement of the sea both in and out of the valley, as in the South-West African basins.
The sand is then transferred into a pot with a hole inside. The subsurface of Ilubirin is totally bituminous. The more marine influences in the adjacent Anamb ra Basin is probably related to the nearness of that basin to the Cretaceous Atlantic Ocean prior to the growth of the Niger Delta.

To the south-west, across the Niger River similar relief is represented in the Yoruba highlands, where the rocky outcrops are surrounded by forest or tall grass and form the major watershed for rivers flowing northwards to the Niger and southwards to the sea.
This heavy oil in tar-sand is commonly referred to as bitumen. We also so the contact between charnockite and porphyritic granite in Babgbe area close to Ondo Town. We also visited the rock contact between gneiss and aplite in Ore, Ondo state. They represent a varied and long lasting — Ma magmatic cycle associated with the Pan-African orogeny. The sandstone friable with grains up to 2 mm in diameter in which the grains are cemented. The low-lying areas are generally below m and these are found in the centre and the south Iloeje, It may also be formed from radioactive bombardment Fasasi et al.
The marble is in three categories: Depobelts, as bj therein, represent successive phase of delta growth. The Kerri-Kerri Formation is characterized by many of the features of peneconcordant sandstone deposits. It is intruded by the Mesozoic calc-alkaline ring complexes Younger Granites of the Jos Plateau and is unconformably overlain by Cretaceous and younger sediments.
In the Ojo-1 Borehole, the interval —1, m which represents the Araromi Formation is Maastrichtian- late Paleocene. These coalfields fall into two main groups: It usually foliated with bands of granular minerals commonly quartz and feldspar koybe with bands of flaky or elongate minerals e. Close to the top of the formation, at 1, m, Foveotricolpites giganteus was recorded.
