Abstract
Ama-Ekpu Edda lies within the Afikpo-Basin,a sedimentary basin set up during the late Cretaceous period following the Santonian uplift in the southern Benue trough.From the field study,the local stratigraphy shows that the lithologic succession consists of black to dark grey shales and sandstone ridges.The Sandstone ridge consist of fine to coarse grain that is fining upward.Palynological analysis from the Shale samples collected from the surface outcrops in the area yielded a total of 210 palynomorphs,made of 9 pollen species ,5 spore species.The abundance of the pollen species of Longasperites sp,Monosulcites sp and Monocolpitesmargiriatus,the spore species of Cyathides minor,Laerigatosporites sp,along with the dinoflagellate cysts species of Leoiaphaerida sp,Andallusiclla sp and Senegalium sp and especially a high abundance of the foraminifera species Bolivina Anambra,suggest a nearly late Campanian to Early Maastrichtian age for the sediments.Based on the distribution of the palynomorphs species recovered from the Shale samples,the study area has been interpreted as an open marginal marine to Estuarine environment at the time of sediment deposition occuring during a period of marine incursion.Hydrogeological investigation of the surface water collected at Ufueseni river shows the presence of coliform which probably results from feacal deposits washed down the river through erosion.
