Formation (Fig. 1) which has been defined as a fine to very fine grained sandstone interbedded with muddy sandstone (Severn 1961; Condon 2000). The upper part of the unit, referred to as the Gebo Member, also contains interbedded carbonaceous shales, claystones, and thin lenticular sandstone beds.

Jun 10, 2021 · The wave and current-rippled sandstone facies (FA4a), flaser-bedded heterolithics (FA4b), and bioturbated muddy heterolithics (FA4c) indicate deposition in a tidal-flat environment. The sandstone with plant debris facies (FA5a) and carbonaceous mudstone and coal seams (FA5b) indicate a coastal plain/swamp environment. The sandstone of the Lokoja and Patti Formations constitutes the main reservoirs of the southern Bida Basin, Nigeria. Detailed facies analysis and diagenesis of these reservoirs intervals in the formations have not received significant investigations. The goal of this study was to apply field observation, facies analysis, sedimentological, … ….
