Subsurface Sedimentary Thickness and Structural types of Formations in Imo State, Nigeria, from Airborne Gravity Data

Imo state is among the states that make up the region referred to as the Niger delta of Nigeria, although, not all parts of it are deltaic in nature. The Niger delta is one of the major basins in Nigeria and is rich with several mineral resources [1], although, more attention is focused on the exploration of hydrocarbon resources in the region. For this reason a lot of geophysical exploratory actives have taken place and is still on going in the region [2] to explore and exploit these resources. Ideally a geophysical exploration aims at obtaining information on the structure, stratigraphy and content of a subsurface using data from different measured parameters [3].
