Basically, geological mapping involves the study of rocks; in situ, that is, in their natural environment and the representation of such rocks on a geological map. Furthermore, rocks of the Igarra area constitute part of the Basement Complex of southwestern Nigeria. On the basis of field relationships and petrological studies, these rocks can be grouped into gneissic rocks, meta-sedimentary assemblages, intrusive igneous rock bodies and sedimentary rocks (formations). T...
Field relationship, petrographical studies and geochemical analysis were combined in investigating the depositional environment and industrial viability of limestone beds in Purechem’s quarry at Onigbedu. Field observation indicates a homogenous lithology of the beds with variation in textural and clastic composition. Petrographic study revealed that the limestone falls under the Biospamicrite and Wackestone classification based on the works of Folks, (1959) and Dunham, (1962) respectively....
Seismic survey has long become a trusted tool for hydrocarbon exploration. This is because of the outstanding ability of seismic reflections and their over lapping relationships to image deep and shallow subsurface structures and delineate promising structural and stratigraphic traps. These subsurface features become good prospecting targets, maybe because of their depositional history or post depositional events. With this in mind, it is necessary to draw out relationships between deposition...
