“…Vindhyan sedimentation took place in a dominantly shallow marine depositional setting (Chanda and Bhattacharyya, 1982;Bose et al, 2001). Bose et al (1997Bose et al ( , 2001 proposed that lower Vindhyan sedimentation took place in an intracratonic rift basin; they also documented the transition from rift basin to intracratonic sag basin during deposition of the upper Vindhyan.…”

“…Bose et al, 1997). The basal contact of this shorefacebeach sandstone appears to be planar or erosional for individual sections, but by correlating all localities of this section above the maximum flooding surface, the erosional contact becomes more evident; the contact shows down-stepping along SW to NE directions (Fig.…”

The present paper highlights the sequence development within the Mesoproterozoic Koldaha Shale Member of the Kheinjua Formation, Vindhyan Supergroup which records the occurrence of a forced regressive wedge and associated discontinuity surfaces at the base of the wedge. Nine lithofacies have been identified within the study area that are grouped into three lithofacies associations varying in depositional setting from outer shelf, through shorefaceforeshore-beach to continental braidplain. The outer shelf sediments are aggradational to slightly progradational representing highstand systems tract. The rapidly progradational, wedge-shaped shoreface to foreshore-beach succession occurs sharply or erosively above the outer shelf sediments and is bounded by a regressive surface of marine erosion (RSME) at the base and by a subaerial unconformity at the top. This, along with its downstepping trajectory, supports deposition of this sedimentary wedge during falling sea level. A laterally extensive soft sediment deformation zone occurs at the base of the wedge.The forced regressive wedge is incised by fluvial braidplain deposits that rest on an erosive surface representing a sequence boundary. The thin braidplain deposits are the product of aggradation during a subsequent early rise in relative sea level, and thus, they are inferred to represent a lowstand systems tract. The constituent architectural elements that characterize the braidplain deposits are downstream accretion elements and small channel elements. Further 1 landward, the base and top of the shoreface wedge merge to form an unconformity across deposits that rest directly on the outer shelf sediments. The identification of forced regressive wedges has significant economic importance in view of the potential occurrence of hydrocarbons within the Proterozoic formations.

“…Slump deformational structures were observed to occur in the form of complex recumbent fold and concave upwards structure and they are confined between undeformed beds at their upper and lower limits. From the concave upwards structure, it is apparent that the deformation event involved slumping and sliding and these slump folds are interpreted as a product of earthquake -related slope failure and slumping (Kleverlan, 1987;Guiraud and Plazait, 1993;Bose et al, 1997).…”

Several soft sediment deformational structures were identified during fieldwork survey carried out on exposures of Gombe Formation in the Gongola sub-basin of the Northern Benue Trough at Gombe and environs. These soft sediment deformational structures includes: simple internal cusps, which occur wide spread across a single bed or intermittently across several beds, and slump structures that are represented by complex recumbent folds and concave upwards structures. These structures are proxy to syn-depositional energy operating within the depositional environment and this current research aims to evaluate their trigger mechanism. These deformational structures are commonly hosted in the mouth-bar deltaic sequences of the Gombe Formation. The deltaic setting is usually a locus for high sediment influx and accumulation. This may have generated high quantum of depositional energy which was probably responsible for the development of the syn-depositional soft sediment depositional structures in the Gombe Formation during Campano-Maastrichtian times.
