Muglad Basin is an intracontinental rift basin in Africa

and its tectonic evolution process can be divided into three stages

including initial rifting in early of the Early Cretaceous inherited rifting in late of the Early Cretaceous to the Late Cretaceous

and depression in the Cenozoic.At the end of the Late Cretaceous

the Muglad Basin was strongly modified by the strike-slip movement of the Central African Fault

superimposing strike slipping deformation on the rifting structures of the Tullus Sag and the Bagarra Sag

and also causing an obvious tectonic inversion in south part of the basin.At the initial rifting stage

the basin was filled with semi-deep or deep lacustrine mudstones which were good source rocks;at the inherited rifting stage

the basin developed va-rious types of sandstone as reservoirs and thick mudstone as regional seals.The favorable source-reservoir-cap rocks combination gives the basin large exploration potential.Later modification of the basin has been an important geological issue for evaluation of oil and gas exploration.
