Investigated sections were subdivided into three third-order sequences, named S1, S2 and S3. Based on extensive micro-and biofacies documentation, five lithofacies associations were defined and their respective depositional environments were interpreted. The shallow-water carbonates of the Middle Eocene in northern Egypt represent a Tethyan reef-rimmed carbonate platform with bedded inner-platform facies. Smout who published in 1954 an important geological document on Qatar the latter is provided in its entirety in appendix 3. Walter Sugden (geologist in Qatar in the 1950's) and the son and daughter of Dr. Standring (paleontologist who worked on the first Qatar deep well DK-0065 in 1959), the son of Mr. Several email communications also took place between the author and Mr. Claude Cavelier (first color geological map of Qatar and still the most extensive geological survey of the country). Abdallah Salatt (first Qatari geologist) and Dr. In addition to gathering all this publicly available information into one complete file, the document contains some unique items such as the transcripts of interviews with Mr. Up to now, all this information was scattered throughout several public domain papers and records, or very difficult to access. The document as a whole is an extremely valuable source of historical information for who ever wants to understand the background history behind the stratigraphical units in Qatar as we know them today. The studies provided information on the economic potential of aggregates, clay, hydraulic binders, and building stones, and the prediction of subsidence-prone areas. Ferric iron-oxide hydrates were the result of oxidizing conditions but their parent material furnished evidence of less-oxygenated conditions and a rising sea level during the Lutetian transgression. Ferricretes were derived from iron-bearing phyllosilicates and disulfides. Phosphate was reworked and concentrated above the Ypresian-Lutetian unconformity. Diagenetic processes and the pervasive etching of the landscape formed ferrous, siliceous, and gypsiferous duricrusts. Extensional faulting was succeeded by a compressional phase that caused the reactivation of some normal faults as steeply dipping reverse faults. Minor unconformities and NE-trending faults of post-Miocene age resulted from the interplay of local diapiric salt movements in the Dukhan anticline and a regionally changing stress field. Following this hiatus, a Lutetian transgressive system tract evolved that was terminated by a maximum flooding surface correlated with the named MFS Pg20. In the Dukhan study area, the most prominent sequence boundary was near the Ypresian-Lutetian boundary.

Small-scale cycles and major unconformities resulted from eustatic sea-level changes. Coarsening-upward sequences with fine-grained muddy sediments at the base and grainstones and boundstones on top attested to a cyclic change in the energy regime. Sedimentation began on a dolomitic carbonate shelf, which gave way to a mixed carbonate-siliciclastic shelf that became increasingly calcitic. The early Tertiary was a time of shallow-marine sedimentation and several transgressive and regressive cycles occurred.

The variable resistance to weathering of the Tertiary sediments is responsible for the general low-relief landscape interspersed with flat-topped hills, the most prominent of which are in western Qatar where they are the surface expression of the Dukhan anticline.

Early Tertiary sediments are widely exposed in Qatar and only in coastal areas and a few places inland do Holocene deposits mask them.
