چکیده
Abstract
The straddled area of the northern Anambra Basin and southern Mid-Niger Basins is been studied for its palynomorphs and micropalaeotological contents. The mappable lithostratigraphic units are the Mamu and Ajali Formations in the northern Anambra Basin and the Lokoja, Patti, and Agbaja Formations in the southern Mid-Niger Basin. The Ajali Formation is made up mostly of sandstones unit and the Mamu Formation of the northern Anambra Basin comprises mostly of claystones, siltstones, shale, and coal units and shows the presence of cleistosphaeridium cf., Leptolepidite major. Triporites sp. Lycopodiacidites asperatus, Retitricolporites cf., Milforda sp, Ephredites sp. which are all palynomorphs and lots of plant cuticles and megaspores indicating some form of a continental environment of deposition for that part of the basin. The assemblages found in the southern Mid-Niger Basin are dominated by phytoclasts, plant fragments, megaspores, and palynomorphs present in moderate to good preservation depicting continental to shallow marine environment. Foraminifera and palynomorphs which are predominantly Maastrichtian in age and the palynomorphs comprises of Echitriporites triangulate, Longaprtites marginantus, Barculatisporites sp., Cingulatisporites sp., Ephredites sp., Stephanocolporate zonorate, Florentina sp. were equally recovered and points to marshy-swampy environments for that stratigraphic section of the straddled part of the basin.
