“…The NE-SW and NW-SE trends in the study area are indicative of Pan-African orogeny fracture systems that predate the rifting of the Benue and Niger Troughs and can be interpreted as significant features of the tectonic framework of the Nigerian Basement Complex (Kogbe, 1983;Ananaba, 1983;Oluyide, 1988). According to Onyedim et al (2004), the NW-SE trending faults form a conjugate pair with the NE-SW faults within the fracture system of the Nigerian Basement Complex. The Benue trend of lineaments, according to Nwajide (2013), is o o between 40 and 73 (NE-SW and ENE-WSW) and is almost always dominant in the whole Benue Trough.…”

The Bouguer anomaly map of part of the Middle Benue Trough, Nigeria, was used to investigate the genetic relationship between the basement and intra-sedimentary structures in the study area. This was with a view to establishing the evidence of possible basement controlled faulting of the Cretaceous strata. Regional-residual separation of the anomalies was carried out to produce the gravity maps associated with crustal masses at deep and intermediate depth layers. The derived maps were further processed to produce Horizontal Gradient Magnitude (HGM) maps that were used to infer deep seated structures and structures existing at intermediate depth layer of the study area. HGM maxima of the anomaly at various altitudes of upward continuation were used to highlight the locations and dip directions of subsurface structures as controlled from deep to shallow zones. The results of this study showed that the structures at different depth layers dominantly trend in the same direction (N-S, NNE-SSW and NE-SW) and that the deep seated faults reflect structurally in the overlying sedimentary column. It was therefore concluded that basement faulting might have influenced the structures in the overlying sedimentary rocks.

“…The rift model theory was proposed at inception by earlier workers and supported to date [1,2,3,4] indicating initiation through tensional regimes induced by mantle plume convection activities [5,6]. This is opposed to the pull-apart model because of the absences of boundary fault that are proxy to rifting, therefore considered the trough as of strike-slip tectonic origin, as it falls in tune and orientation to the major transcurrent fault systems of the Romanche, Chain and Charcot suture zones [7,8,9]. The opening of the trough is accompanied by transgressive and regressive sequences in the Aptian-Albian times with the Northern Benue Trough characterized by continental depositional regimes.…”

This research aims to evaluate the facies and facies association of the Yolde Formation at Kware stream in the Gongola Sub-basin of the Northern Benue Trough with objective of characterizing its paleodepositional environment. Six lithofacies consisting of trough crossbedded sandstone facies (St), massive bedded sandstone facies (Sm), planar crossbedded sandstone facies (Sp), ripple laminated sandstone facies (Sr), parallel sandstone facies (Sl) and mudstone facies (Fm) defining its stratal packages were skewed into distinctive assemblages of flaser, wavy and lenticular bedding. This present a fining upward signature with facies association typical of tidal flat system. This is evident of a coastal progradation with sequences reflecting migration of a supra-tidal mudflat over intertidal mixed-flat zone which progressively superposed subtidal sandflats. This is indicative of a coastal shoreline with a relatively progradational phase within the net transgressive regional framework of the Cretaceous Yolde Formation.

Facies evaluation carried out on the Yolde Formation at Gabukka locality in the Gongola Sub-basin of the Northern Benue Trough was aimed at enacting its paleo-depositional environment. The formation at this locality revealed an intercalated succession of massive bedded sandstone facies (Sm), planar crossbedded sandstone facies (Sp), ripple laminated sandstone facies (Sr), parallel laminated sandstone facies (Sl) and mudstone facies (Fm). These successions developed a thinning and thickening stratigraphic profile depicting periodic rhythmic signatures indicating deposits of tidal rhythmites. Thickening rhythmic packages are reflective of a spring tide whereas thinning phases are indicative of neap tide. These depositional sequences are genetic to intense tides conditions, thus an indexing a tide dominated oceanographic within the course of development of the Cretaceous Yolde Formation.
