The section here was small and the rocks hard , making collecting difficult. No section was logged. LITHOFACIES AND FAUNAL ASSEMBLAGES A total of 14 sections were logged and their macrofauna recorded. Lithological samples were collected systematically from the thickest sequence, (Jebel Rawdah, section 2), and sectioned for petrographic analysis. The lithological descrip- tions given for other sections are based solely on field observations and are consequently of a preliminary nature. The results of this work are summarized in the measured sections (Figs 5-11) and in the faunal lists of the Appendix. As the successions in the various jebels differ significantly and correlation between jebels was not initially obvious, each succession is documented in turn before attempting a synthe- sis. Jebel Rawdah (Figs 5-7) 1. Sedimentary lithofacies at section 2. From field logging and petrographic analysis we recognize the following major litho- facies: Fades 1. The succession commences with an ultrabasic clast conglomerate (bed 1). This can reach more than 10 m in thickness in places, and comprises well-rounded clasts of mean size 10-20 cm. There are rare rounded fragments of rudist and occasional acteonellid gas
