Structural geometry of Muglad Basin,Central Africa

This paper has studied the relationship between structural characteristics and hydrocarbon accumulation of the Muglad rift basin and also applied basin analysis to investigate the complex geometric tectonic characteristics of the basin.It suggests that the tectonic unit of the Muglad Basin is generally of asymmetric half graben,formed by two groups of half-grabens and half-horsts controlled by basement faults with NEE and NW trending.Half-grabens alternate asymmetrically by adjusting their distortion or displacement.The sags are relatively independent with separate tectonic systems and sedimentary systems,which become basic units for hydrocarbon generation,migration and accumulation.Big tectonic accommodation zones and successive low relief uplifts,developed between half grabens,are prolific with oil and gas.
