“…The resultant NE-SW trending basins and swells within the shelf controlled sedimentation in north Eastern Desert and north Sinai. Over there, the Coniacian-Maastrichtian successions exhibit obvious imprints of compression, basin inversion, folding, reverse faulting and uplift as a result of the activation of the Syrian Arc Fold System (Shahar, 1994). It has to be pointed out that the lateral facies and thickness variations, tectonic influence sea-level change and discrepancy in discontinuities and their time spans are evidences suggesting that the west central Sinai was not a tectonically quiet area during the Coniacian-Santonian time.…”

“…Krenkel 1925;Moustafa and Khalil 1995;Hussein and Abd-Allah 2001). During the Early Eocene, a major phase of tectonic activity occured along the Syrian Arc-Fold-Belt (Shahar 1994). Regional uplift and subsidence triggered the formation of ENE-WSW striking basins, submarine swells and subaerially exposed plateaus on the unstable shelf (Said 1990;Schütz 1994;Fig.…”

“…In the Early Eocene, the Egyptian shelf is especially strongly aVected by tectonism, which is related to the northward movement of the African craton towards Eurasia as well as the reactivation of Mesozoic fault systems (e.g. Shahar 1994; Moustafa and Khalil 1995;Hussein and Abd-Allah 2001). Thus, the evolution of carbonate platforms at the Egyptian shelf is controlled by those tectonic constraints and requires a regional approach beyond the general platform stages of Scheibner et al (2005).…”

The succession of the Galala Mountains at the southern Tethyan margin (Eastern Desert, Egypt) provides new data for the evolution of an isolated carbonate platform in the Early Eocene. Since the Late Cretaceous emergence of the Galala platform, its evolution has been controlled strongly by eustatic sea-level Xuctuations and the tectonic activity along the Syrian Arc-Fold-Belt. Previous studies introduced Wve platform stages to describe platform evolution from the Maastrichtian (stage A) to the latest Paleocene shift from a platform to ramp morphology (stage E). A Wrst Early Eocene stage F was tentatively introduced but not described in detail. In this study, we continue the work at the Galala platform, focussing on Early Eocene platform evolution, microfacies analysis and the distribution of larger benthic foraminifera on a south-dipping inner ramp to basin transect. We redeWne the tentative platform stage F and introduce two new platform stages (stage G and H) by means of the distribution of 13 facies types and syn-depositional tectonism. In the earliest Eocene (stage F, NP 9b-NP 11), facies patterns indicate mainly aggradation of the ramp system. The Wrst occurrence of isolated sandstone beds at the mid ramp reXects a post-Paleocene-Eocene thermal maximum (PETM) reactivation of a Cretaceous fault system, yielding to the tectonic uplift of Mesozoic and Palaeozoic siliciclastics. As a consequence, the Paleocene ramp with pure carbonate deposition shifted to a mixed carbonate-siliciclastic system during stage F. The subsequent platform stage G (NP 11-NP 14a) is characterised by a deepening trend at the mid ramp, resulting in the retrogradation of the platform. The increasing deposition of quartzrich sandstones at the mid ramp reXects the enhanced erosion of Mesozoic and Palaeozoic deposits. In contrast to the deepening trend at the mid ramp, the deposition of cyclic tidalites reXects a coeval shallowing and the temporarily subaerial exposure of inner ramp environments. This oppositional trend is related to the continuing uplift along the Syrian Arc-Fold-Belt in stage G. Platform stage H (NP 14a-?) demonstrates the termination of Syrian Arc uplift and the recovery from a mixed siliciclastic carbonate platform to pure carbonate deposition.

“…It was, as such, subjected in the past to Neogene sea ingression from the west. The valley is obliquely crossed and underlain by a series of NE-SW directed anticlines and synclines of the Syrian Arc system (Shahar 1994). The stratigraphic sequence (Table 1) of Triassic to Quaternary age is exposed in the valley and its southern and northern margins and was penetrated by wells in the study area.…”

Detection of Saline Groundwater Bodies between the Dead Sea and the Mediterranean Sea, Israel, Using the TDEM Method and Hydrochemical Parameters

A Time Domain ElectroMagnetic (TDEM) survey coupled with hydrogeological information was carried out along the Be'er Sheva valley between the Mediterranean Sea and the Dead Sea base levels, aiming to obtain the subsurface distribution of the different fresh and saline water bodies. Hydrochemical considerations and previous TDEM results hinted that the previously accepted model of an upper fresh water body underlain by solely Dead Sea (R-type) brines in the east and C-type brines in the west does not match the actual observations. Thus, the suggested working hypothesis of additional intruding seawater from the Mediterranean Sea to the Dead Sea base level was checked by the TDEM method. The results, indeed, exhibit an upper high resistivity fresh water body, an underlying low resistivity brine body and a moderate resistivity body in between. The origin of this body is not uniquely determined based on the geophysical measurements alone. Analysis of borehole data testifies that hydrochemical parameters of the body cannot be solely interpreted as a mixture of the above two end members, but rather calls for an additional contribution of intruding seawater. The suggested configuration consists of an upper fresh water body flowing to both base levels in the west and the east. Underneath there is a saline body resulting from seawater intrusion reaching from the Mediterranean to the Dead Sea base level. At the bottom there is a third body of the westward density driven Dead Sea brine. The entire configuration is supported by results of subsurface flow modeling.
