Organic petrography and petroleum source rock evaluation of the Cretaceous Mamfe Formation, Mamfe basin, southwest Cameroon

International Journal of Coal Geology, 2019
Abstract The Mamfe basin is thought to be a rift splay segment of the southern Benue Trough and is genetically link to the Abakaliki and Anambra sub-basins in Nigeria. In the Mamfe basin very little studies have been done on maceral characterization and hydrocarbon generative potential of the Cretaceous black shale.

The Ikom-Mamfe basin, Nigeria: A study of fracture and mineral vein lineament trends and Cretaceous deformations

Journal of African Earth Sciences, 2015
Abstract The Ikom-Mamfe basin is approximately a 130 km long, east–west abutment onto the eastern flank of the lower Benue trough of Nigeria and extends westwards into Cameroon. Two hundred and six fracture lineaments were analyzed in the Nigerian sector of this basin.

Provenance and depositional history of Mesozoic sediments from the Mamfe basin and Douala sub-basin (SW Cameroon) unraveled by geochemical analysis

Journal of African Earth Sciences, 2019
Abstract Mineralogical and geochemical analytical methods were employed to characterize sediment samples from the Mamfe basin (MB) and Douala sub-basin (DSB) in order to constrain the provenance, weathering, paleoclimate, and depositional history of rocks from both basins.

Geochemical characteristics of shales in the Mamfe Basin, South West Cameroon: Implication for depositional environments and oxidation conditions

Journal of African Earth Sciences, 2019
Abstract Field and laboratory studies were carried out with the aim of characterizing the depositional environment and oxidation conditions during accumulation of shales in the Mamfe basin. Field studies denoted that the shales were black to dark grey in color, sub-tabular to tabular in occurrence, with some (n = 20) reacting vigorously with dilute ...

U–Pb Zircon Age Constraining the Source and Provenance of Gem‐Bearing Late Cenozoic Detrital Deposits, Mamfe Basin, SW Cameroon

Resource Geology, 2012
AbstractZircons and other heavy minerals (corundum, rutile, ilmenite, magnetite, sillimanite) are identified in the Nsanaragati gem corundum placer deposit, in the western part of the Mamfe sedimentary basin, SW Cameroon. These alluvial minerals have different morphological characteristics and zircons, in particular, vary mostly in colour and shape ...
