This book highlights a detailed high-resolution palynofacies origin and depositional environment, source rock potential, hydrocarbon migration pathway and structural hydrocarbon entrapment mechanisms of the outcrop lithostratigraphic units of the inland Anambra basin. It broadens readers’ geoscientific conceptualization in the appraisal of the quantity and quality of outcrop scale, generated chemical macerated palynofacies elements and kerogen maturation synthesis, palynofacies hydrodynamics and sedimentary structures trapping orientation and configurations, structural mechanics and lateral facies changes. This boils down to perfect comprehension of the sedimentary, palaeontological data and natural plant evolution, growth and depositional processes in order to authenticate their origin and provenance, depositional environment and hydrocarbon production potential within the context of the basin. Presence of texturally mature coarse- to fine-grained sandstones, variable sedimentary structures, internal bed geometries and nature of bedding, age and palynofacies hydrodynamics are vital prognostic stratigraphic and paleoenvironment indices culminated in the kerogen types, organic thermal maturation, seals and reservoir rock quality along with kinematics-driven faults and joints in time and space. These geoscientific concepts were summarily authenticated in the specific objectives and chapter series of this book along with modelled prognosis for potential conventional and unconventional hydrocarbon prospects to contribute more information to oil exploration campaign in the inland basin.
