Abstract
Muglad basin is the major part of Sudan rift system, which in turn, is a main component of West and Central Africa Rift-related System (WCARS). Sedimentary sequences of Muglad rift basin consist of nonmarine sequences of lacustrine and fluvial/alluvial facies of early Cretaceous to late Tertiary age directly rested upon the Precambrian basement. Muglad basin had passed through three sedimentary cycles. First sedimentary cycle began from early Cretaceous and its termination is marked, stratigraphically, by basin wide deposition of the thick sandstone of the Bentiu Formation. Second sedimentary cycle, occurred in late Cretaceous and seen in the widespread deposition of lacustrine and flood plain claystones and siltstones.
