- 62 -Additional mechanisms for transporting siliciclastics from nearshore areas in Egypt into the deepbasin could have been: (1) Oligocene coarse clastics deposits in northern Egypt could have been asource for potential basin floor sheet sands, transported by canyons and channels runningnorthwards across the Egyptian slope; (2) Longshore currents that interact with tidal currentsdiverting the drifting load of sand down the slope (Boyd et al, 2008). Study of these two suggestedmechanisms is beyond the scope of the present report.In summary, the Oligocene to Late Miocene periods are characterized by widespread transport ofclastic sediment into the deep basin via submarine canyon and channel systems along the Levantmargin. The provenance of these siliciclastic sediments were both continental and near-shore Oligo-Miocene deposits, recycled from Nubian sandstone (Fig. 33).6.3 The Middle to Late Miocene successionThe upper Tortonian is associated with submarine incision on the Levant slope, depicted by the LateMiocene unconformity (Fig. 17). The canyon pattern closely followed the older, base Oligocenesystem, although the incision appears to have been more widespread.Coarse clastic material was transported basinward through the Late Miocene canyon system.Evidence for clastic deposition is found along the Afiq Canyon. A 250 m thick conglomerateinterpreted as channel fill of debris flow was found in the Nahal Oz-1 borehole, located in aproximal part of the canyon, at the southern Coastal Plain (Fig. 22). Further downdip, the Gad-1borehole penetrated a 477 m thick clastic section composed of alternation of sandstone,conglomerate and clay of ?Middle Miocene to Messinian age (Figs. 22 and 36) (Buchbinder et al.,2006). The section includes 200 m of sand with average porosity of 16-19%. On the seismicrecords, it appears as a series of high-amplitude events onlapping the Afiq Canyon wall (Fig. 36).These are interpreted as stacked channels and channel-levee complexes.Additional channel fill deposits, of apparent Langhian age (Siman-Tov, 2008b), were encounteredin the Netanya-2 borehole, and located in the Netanya tributary of the Ashdod Canyon. Thesedeposits consist of a conglomerate (100 m thick), of limestone and chert pebbles, and quartz sandgrains (Fig. 27).
