Title: Evaporite Facies in Nubian Sandstone Formation of Sudan: GEOLOGICAL NOTES

Author(s): A. H. Medani (2)


Three different evaporite facies (gypsum, caliche, and halite) are found in the Nubian Sandstone Formation of the central Sudan Republic. The deposits are not widespread, but are sufficiently abundant that they indicate the former existence of a hot arid climate during deposition of part of the Nubian in the central Sudan. However, an arid climate did not prevail during the entire time of Nubian deposition. At other levels in the Nubian, the lithologic evidence suggests that a more humid climate predominated.
