ABSTRACT

Abstract: Palynological baseline data acquisition and analysis were carried out within longitude 6 E and latitude 8 N spanning the area from middle to southern Benue Trough for the purpose of forensic studies. A total of seventeen samples were collected from Northern to Southern town axis from Akunza Migili Lafia town to Ikot Ekpene road Abia state. A lithologic section was prepared using latitude from the northern to southern axis. The lithologic and palynological analysis based on field samples were tied up with the geologic formation based on published geologic maps. The rocks were compose of shale and sandstone, therefore found to traverse within middle Benue Trough (Akunza Migili Lafia Nasarawa State-Oturkpa Benue State), lower Benue Trough (Nkalagu- Enohia-Nkalu Afikpo Ebonyi State) and Niger Delta (Abia state boundary between Umuahia and Imo State-Ikot Ekpene road Abia State) from a geographic spread between longitude 6 E and latitude 8 N. Palynologic analysis yielded; Echitricolpites spinosus, Fenetrites spinosus; from middle Benue Trough, Echimonocolpites rarispinosus, Cingulatisporites ornatus, Macrotyloma brevicaules, Tubistephanocolpites cylindricus, Hexaporotricolpites emelianova, Retidiporities magdalenensis, Retistephanoclpites gracillis, Elaeis guineensis; from Nsukka Formation, Multiarolites formosus, Echitricolpites spinosus, Nympheapollis clarus; from Benin Formation. These data were used to generate palaeogeographical distribution of pollen, spore, fungal spore, dinoflagellate, acritarch, foram test wall lining and diatom. The palaeogeographical distribution charts were converted into percentage charts which shows the comparative occurrences of the different palynomorph groups. These are represented in step-like manner indicating the entrance of two to three new species marks a biozones. The occurrences of environmental diagnostic palynomorphs within a specific latitude range leads to the interpretation of the environment of deposition indicating sedimentation from alluvial plain to transitional/tidal zone and the diagnostic palynomorphs shows that the paleoecology consists of rainforest to mangrove.
