Figure 3: Paleofacies of the Late Permian. This time period spanned the deposition of the Khuff, Karmia, and Amanous formations, and their regional equivalents [MFS P20 to intra-Tr10].The Khuff was deposited on the new northeastern passive margin with Neo-Tethys. A major Late-Permian unconformity occurred within P20. With information from: Al Jallal (1995); Andrews (1991, 1992a); Béchennec et al. (1989); Garfunkel (1989); Guiraud et al.
