Abstract
Based on field investigation of twenty eight vertical and lateral sedimentary profiles in the Gedaref area, nine sedimentary facies have been identified based on lithofacies analysis. The identified sedimentary facies are named: matrix-supported massive conglomerate (Gmm), trough cross-bedded sandstone (St), planner cross-bedded sandstone (Sp), ripple cross-lamination sandstone (Sr), horizontal-bedded sandstone (Sh), massive sandstone (Sm), laminated sandstone and mudstone (Fl), massive mudstone (Fsm) and paleosol (P). These facies are grouped into three sedimentary facies associations: FA1consists: Sp, Sm, Sh ± (Fsm, St, P and Fl) representing sandy fluvial channel; FA2 include: Sm, Gmm, St ± (Fsm and Sh) representing sandy point bars and FA3 consists: Fsm, Fl ± (St and Sh) representing lake deposits. These associations indicate that the studied sediments have been deposited under fluvial conditions (multi braided and meandering channels) in Wad Hari and Rumeila respectively, shifted into lacustrine settings at Magareef and Rashed areas towards the basin center. Paleo-current data indicate that the source area was located southeast of the study area.
