ABSTRACT

Pollen and spores recovered from cutting samples of five wells drilled in Bagbag Basin in Northern Kordofan, central Sudan, indicate a Coniacian to Maastrichtian age for a discrete sedimentary unit in the basin. The age assignment is based on the ranges of the identified species in Africa and northern South America. This distinct sedimentary unit has been preserved from erosion by deep seated, north-westwards trending faults along the borders of the Bagbag Basin. The tectono-stratigraphic significance of this unit is indicated by the position of bagbag Basin within the Central African Fault Zone (CAFZ), and it demonstrates that the Tertiary tectonic activity documented in the Sudanese rift basins south of this lineament did not, in fact, occur within and presumably north of the CAFZ.
