Gravity studies also confirm central positive anomalies flanked by negative anomalies as shown for the adjacent Benue Trough and typical of rift yb Ojo, ; Ojo and Ajakaiye, Please enter recipient e-mail address es. Saka Nuru and R. Find more information about: Most of the area lies between to m however the Idanre Hills, where the Plateau is highest are about 1 m above sea level Iloeje, Such relict niferia tend geopogy reinforce the assertion that this Precambrian terrain may have been part of an Archaean proto shield which was later gdology by Proterozoic crustal activities and subsequent evolvement of the Phanerozoic basins.

Probable reserves estimated by open cast and in-situ technique is 42 billion barrels. Please enter your name. Under the Ogu formation we have the Ezeaku followed by the Keana and then the Awe formation, with the Asu group at the bottom.

This sequence is overlain by herringbone crossbedded mature sandstones of the Geoligy Formation MiddleMaastrichtian in the northern fringes of the basin hence providing strong evidence for shallow marine, deltaic to intertidal depositional environments for the Maastrichtia n sediments of the Anambra Basin.

Lowland areas also exist in the Rima and Chad basins at the extreme north-west and north-east of the country respectively. The Middle Benue Trough D. The borehole cores of the Steel RawMaterials Exploration Agency formerly National Steel Council stock-piled at the Obi camp contain coal seams and coal bands at various depths within the Awgu Formation.

Olade described ingeria Itakpe Hill deposit, the largest of several similar deposits in the district, as a hematite-magnetite quartz body, and termed it as a ferruginous quartzite of the Itabirite type. The vitrinite reflectance values of the coals 0.

The aim of the field trip was to expose students to the regional geology of the country, which have hitherto been studied theoretically. The former comprises predominantly unconsolidated sands with intercalations of grey shale, mudstone, silt and clay while the latter consists of dark grey and black shales with interbeds of sandstone, limestone, marl, and silty and glauconitic shale.

Similarly to the east, no schist belts are known for a distance of km until in Cameroun where a number of schist belts, considered to be Upper Proterozoic, occur in the Pan- African granite- migmatite terrain north of the Congo Craton. Bauchi, Ebonyi, Plateau, Taraba The environments of deposition of the saline sediments of the Benue Trough are different from those of the South Atlantic basins.

These formations represent full marine incursion into the Upper Benue during the Turonian — Santonian times. The tar-sand is composed of sand, heavy oil bitumenmineral-rich clay and water in varying proportions.

The Lafia-Obi coal was expected to produce for the Ajaokuta steel complex at the rate of 50, tonnes per annum. Grit is a type of coarse grained sandstone with angular grains. Eight of these are locally developed.

They are generally high level intrusions and anatexis has played an important role Rahaman, WorldCat is the world’s largest library catalog, helping you find library materials online. The name field is required. Trace elements are often not limiting on the soils in nigeroa zone.

Subjects Geology — Nigeria — Congresses. Some portions are highly coloured exposed by influence of the river. Undeformed Acid and Basic Dykes 2. As seepages in farmlands, seen only in hot days with underlying sandstone in the reservoir.

Initial stages in development of the complexes involved intrusion of vast amounts of acid lavas, tuffs and ignimbrites, now only partly preserved as a result of subsidence along ring faults. Soils with a high base saturation under forest vegetation Semi-arid tropics — Alfiso ls, Inceptisols, Gleysols and Cambisols.

The highest part is the Shere Hills north-east of Jos where the elevation exceeds 1 m above sea level Iloeje, We proceeded to the coal seam very close to Onyeama coal seam, kovbe Enugu. Field geology means nigeriia work Finki, geology, as practiced by direct observation of outcrops, exposures, landscapes, and drill cores.

The Njgeria charnockite was veology by Dada to be typically greenish black, fine to medium-grained, equigranular and massive, sometimes porphyritic. The reported occurrence of the foraminifera Eponides pseudoelevatus Graham et al.

Omatsola and Adegoke disagreed with this nomenclature on two main grounds. The lithostratigraphic unit does not occur in outcrops. The length of cropping can be increased to two years before N and P fertilizer can be limiting. The raw materials used for the production of cement include: Fayalite hedenbergite quartz porphyry often has ignimbritic textures.
