The Southern Benue trough and Anambra Basin, Southeastern Nigeria: A Stratigraphic Review
Journal Title: Journal of Geography, Environment and Earth Science International - Year 2017, Vol 12, Issue 2
Abstract
A review of high impact literature on the Southern Benue Trough and Anambra Basin was undertaken to enhance the understanding and definition of the basins in terms of their evolution, area extent, sedimentation history, as well as their litho- bio- and sequence stratigraphy. Early works of [1,2,3,4], and others, which formed the basis for the stratigraphic study of these basins were employed, but were updated by recent reputable works of [5,6,7,8,9,10] and others. The geologic formations encountered in the basins include: the Asu River Group, Eze-Aku Group, Agbani Sandstone/Awgu Shale Formation, Nkporo Group, Mamu, Ajalli, Nsukka, Imo, Ameki and Ogwashi-Asaba Formations. Controversy surrounding the stratigraphy of the Anambra Basin, depositional environments and conditions, and age of geologic formations present in the study basins were considered. The aspect of sequence stratigraphy requires more work for a more accurate definition of stratigraphic surfaces required for the establishment of systems tracts and sequences.
