Contact Usigneous and metamorphic origin Rose diagrams of paleocurrent directions show predominance of 210o - 240o trend in the eastern margin of Gongola Arm, and a predominance of the 300o - 330o direction in the southern margin of Yola Arm of the Upper Benue Trough Interpretation of the results revealed the crystalline basement of Adamawa, Cameroon ....
Since the southern part of the area lies on the sediment-basement boundary part of the Cretaceous Benue Trough s northern margin , the causative sources were considered to be deeper-seated intra-basement basic intrusive rock bodi The anomaly occurred in the NE-SW and E-W trend following the Benue Trough s general trends...
The northeastern and southern boundaries of the basin bordering some parts of Benue Trough and the Niger Delta are still not very clear due to stacking of the basins 2 There had, however, been strong tendencies in the past to merge the Anambra Basin with the Niger Delta Basin as one extensive coastal basin, or simply to consider one an ....
The Benue Trough is a linear NE-SW trending rift system whose development was closely associated with the separation of Africa from South America and the opening of the South Atlantic Ocean during the Cretaceous The origin and evolution of the Benue Trough are fairly well documented Wright 1968 , Burke et al 1971, Nwachukwu...

The Benue Trough can be sub-divided into lower, middle, and upper parts that were affected by santonian compression which deformed the Benue Trough by inverting the main depocenter of the Abakaliki Trough and subsequently creating the Anambra and Afikpo basin to the north-west and south-east respectively 1,2 The santoniantectonism ....

The Benue Trough in Nigeria is regarded as an example of such a failed arm following the opening of the S Atlantic When oceans eventually close it is possible to recognise these failed arms as depositional basins oriented perpendicular to the collision mountain belt most basins tend to ,...

Jul 15, 2017 0183 32 The aim of this work is to undertake a study on the occurrence of uranium bearing rocks in the area and infer the source, mechanism of migration and structures or rock type hosting uranium mineralization This was achieved by an integration of radiation point count, petrographic studies and structural analysis This is necessary because the Gubrunde uranium occurrence is one of the several ....
The Anambra Basin is a Mesozoic-Cenozoic petroliferous and coal-bearing basin located within the southern Benue Trough which evolution is related to the opening of the Gulf of Guinea and the separation of African and South American Plates sequel to the breakup of Gwandana supercontinent during Late Jurassic to Early Cretaceous tim...
Awgu formations within the Abakaliki-Benue Trough which was flanked to the west by the Anambra platform, and to the southwest by the Ikpe platform The second phase Campanian-Eocene was characterized by compressive movements along the NE-SW axis which resulted in the folding and uplift of the Trough into an anticlinorium...
In the Upper Benue Trough, the boundary bet- ween the Basement Complex and the cover is commonly tectonic, especially along the north- eastern border of the basin where the axial fault system emerged from the trough Fig 5 Near the contact, Albian sediments are commonly severely deformed, largely due to Maastrichtian compres- sion...
Triple junction
Know MoreA triple junction is the point where the boundaries of three tectonic plates meet At the triple junction each of the three boundaries will be one of 3 types - a ridge R , trench T or transform fault F - and triple junctions can be described according to the types of plate margin that meet at them eg Transform-Transform-Trench, Ridge-Ridge-Ridge, or abbreviated F-F-T, R-R-R...
