Some typical flow sedimentary structures were clearly detected within the middle Miocene alternating gypsiferous and anhydritic clays of the evaporitic sequence in Ras Gemsa and Um El-Huweitat localities.
Sedimentologic analyses of the different structural forms revealed that they were originally formed from unlithified sediments and due to submarine flowage. These structures were formed as a result of stress--load, compression, and rotation.
Such a genetic approach is helpful in deducing the environmental conditions within which these sediments accumulated. Degrees of flowage and affected stresses on similar lithologic associations could be considered strong evidence for correlation within the extended Miocene evaporitic sequence along the Red Sea coast.
