In the most stable localities of the NW Red Sea-Gulf of Suez, the Last Interglacial shore deposits have been dated (alpha Th/U) and give evidence of a two-stages 5.5 (5e)+8/5 m transgression subdivided by a 10 m (at least) relative sea-level fall. The respective ages of the initial reef and beach unit and about 3 m lower bay-lagoon-gypsum salina deposits are not discriminable with the available dating method. This high-frequency oscillation during 5.5 highstand would be tentatively interpreted as a glacio-eustatic sea-level fall coinciding with the 5.52 event of delta 18 ?O isotopic terminology.
