Highamplitudeevents on the seismic profile correlate to thin sandstone and carbonate interval, interpreted as channel fillwithin the Oligocene and Middle to Late Miocene canyons. Location is as in Figure 24 (after Samedan, 2003).
- 60 -In the Hadera Canyon the seismic data show several positive, high-amplitude reflections that onlapthe canyon walls (Fig. 35). Amplitude extraction map of one of these events reveal linear featureswith maximum amplitude values (70-80) along the canyon. The high-amplitude event mayrepresent a channel-levee complex where the maximum amplitudes are the coarser-grained, sandyportion of the channel fill.No confined settings were observed in the seismic records in the deep part of the basin, west of theelevated incised fold belt. Nonetheless, high-amplitude seismic events, which are observed at thelower part of the section near the distal outlets of the main canyons (Fig. 11, left side at about 4.7sec), may be associated with unconfined setting of sheet sands and basin floor fans.A 17 m thick sand interval of lower Miocene age was encountered in the Gaza-1 borehole, in theAfiq Canyon, where it crosses the present coast line (Fig. 33). It was interpreted as a channel filldeposits and may represent the proximal tail of much more extensive accumulation furtherdownstream the Afiq Canyon. In the unconfined setting, west of the outlet of the Afiq Canyon intothe Levant deep basin, the seismic records show high-amplitude events below the cyan horizon,(Fig. 11, central part at about 3.7 sec). These seismic events may represent sheet sands generated bybasin floor fans.Notably, continental clastic sediments started to accumulate in proximal inland areas in EarlyOligocene times. The Hazeva Group, several hundred meters thick in the Negev, started toaccumulate before 20 m.y. (Calvo and Bartov, 2001). In the northern part of Israel, the mixedcarbonates-clastic deposites of Hao’n and Nukev Formations and the continental sand deposits ofthe En-Gev Member (Susita Formation) were deposited during the Early Oligocene and EarlyMiocene (Buchbinder et al., 2005). The deposition of the Hordos sands in the Galilee and the GolanHeights was initiated before 17 m.y. (Shaliv, 1991).Shaliv (1991) suggested that the similarities between the En-Gev sands and the continental depositsof the Damascus basin show that the two sites are, in fact, parts of the same basin. All these clasticoccurrences strongly suggest the existence of a widespread source for siliciclastics both in thesouthern and the northern parts of the country (Fig. 33). Clastic deposits could have beentransported into the basin through the Afiq and Ashdod canyons, in south and central Israel, andthrough yet undefined conduits in northern Israel during the Oligocene to Early Miocene time span(Figs. 3 and 33).
