Palyno-maceral and lithological analysis was carried-out on Mamu Formation, northern Anambra Basin, Nigeria. Analyses of the palyno-maceral composition of the exposed shale unit of the Mamu Formation in the northern Anambra Basin at Ojuwo-Olijo revealed that PM-1 and PM-2 were numerous and poorly sorted, as well as medium to small-sized PM-3 and PM-4, accompanied by Structureless Organic Matter (SOM). This scenario suggests predominantly terrestrial deposition conditions, with possible variations towards coastal and lagoonal environments in certain samples.

Palynological and lithofacies analysis was carried-out on dark grey shales and dark sandy clay units from Idah well-1, Northern Anambra Basin, Nigeria. Less attention has been given to hydrocarbon exploration in northern Anambra, hence this necessitated this research. The study aimed at investigating the palynological and lithofacies of study rock types in the study well sections of the basin for paleoenvironmental, paleoclimate, paleoecology and hydrocarbon potential.
