Structural interpretation of Southern Main Ethiopian Rift basin using constrained full tensor gravity inversion of the basement morphology.

ABSTRACT: The Southern Main Ethiopian Rift is part of the great East African Rift system situated within the limit of 37^o-38.5^o east and 5.5^o-7^o north. Unlike the Central and Northern Main Ethiopian Rift where numerous geophysical studies have been conducted, the subsurface geology of Southern Main Ethiopian Rift is poorly constrained. Geological field work on Amaro Horst shows the basement outcrops are dominated by High grade gneisses and Intrusive with an average density of 6 gm/cm³ overlain by Mesozoic sedimentary rocks possibly extend into the studied sub-basins. In addition, field structural measurements and extracted lineaments from digital elevation model show NE-SW, NW-SE and N-S directions in agreement with fault block geometries identi
