AbstractThe structure of the northern part of the Arabian platform is reviewed in the light of hitherto unpublished exploration data and the presently accepted kinematic model of plate motion in the region. The Palmyra and Sinjar zones share a common history of development involving two stages of rifting, one in the Triassic–Jurassic and the other during late Cretaceous to early Tertiary times. Deformation of the Palmyra zone during the Mio-Pliocene is attributed to north–south compression on the eastern block of the Dead Sea transcurrent system which occurred after continental collision in the north in southeast Turkey. The asymmetry of the Palmyra zone is believed to result from northward underthrusting along the southern boundary facilitated by the presence of shallow Triassic evaporites. An important NW-SE cross-plate shear zone has been identified, which can be traced for 600 km and which controls the course of the River Euphrates over long distances in Syria and Iraq. Transcurrent motion along this zone resulted in the formation of narrow grabens during the late Cretaceous which were compressed during the Mio-Pliocene. To a large extent, present day structures in the region result from compressional reactivation of old lineaments within the Arabian plate by the transcurrent motion of the Dead Sea fault zone and subsequent continental collision.


Subject The implications of the Red Sea-Dead Sea plan. Significance Israel and Jordan on February 26 signed an agreement to facilitate water-sharing and address the depletion of the Dead Sea, which is receding at a rate of about a metre per year. The 900 million dollar World Bank-sponsored 'Seas Canal' deal consists of two main aspects: local water exchange deals, with Jordan providing Israel with desalinated water from Aqaba in exchange for bluewater from the Sea of Galilee in the north; and saltwater transfer from the Red Sea to the Dead Sea. The Palestinian Authority is not party to the agreement, and awaits a separate deal with Israel. Impacts Prospects for Palestinian-Israeli water negotiations have drastically decreased. Jordan will still need to agree further desalination and cooperation deals in order to meet demand. Water saving efforts will be pushed aside in favour of much more costly desalination. Desalination powered by burning fossil hydrocarbons accelerates global warming.

The Hebrew scrolls newly discovered near Qumran at the north-western shore of the Dead Sea, which are attracting more and more the attention of New Testament students, are also very important for the evolution of Jewish Gnosticism. One may think especially of the fact that in some of these manuscripts the Hebrew word for ‘knowledge’ and related terms occur with a striking frequency, and that the dualistic cosmology of the new texts seems to be rather like certain fundamental ideas of Gnosticism. Since the archaeological evidence now proves that the Qumran manuscripts are pre-Christian, or were at least written in the first Christian century, one may very well state that new light can now be thrown upon the much debated question of a pre-Christian, Jewish Gnosticism.

The Dead Sea occupies a linear down-dropped region between two roughly parallel faults along the central segment of the major northsouth- trending crustal rift that extends about 1,100 km from the Red Sea through the Gulf of Elath to Turkey. This rift or geosuture separates the Arabian crustal sub-plate on the east from the Sinai one on the west. An origin as early as Precambrian is possible (Bender, 1974; Zilberfarb, 1978). Crystalline crust along the north-south trough of the Sinai sub-plate is about 40 km thick in contrast with a thickness of half as much above ridges along both flanks (Ginsburg and Gvirtzman, 1979). Toward the north the ridges appear to converge (Neev, Greenfield, and Hall, 1985). Since the Miocene period the Arabian plate has moved north about 105 km relative to the Sinai plate. This sort of crustal movement along either side of a rift is termed strike-slip faulting. One result of it was the opening of the Red Sea relative to the Gulf of Suez. The Dead Sea graben, a down-dropped block between two roughly parallel faults, occupies the central segment of the long crustal rift. The boundary between these is rather sharp along the east shore of the sea (Frieslander and Ben-Avraham, 1989). Actual post-Miocene movement was along not just a single major fault but was distributed among numerous sub-parallel faults that form a 100-km-wide belt in which movements were transferred from one fault to another (Eyal et al., 1981; Gilat and Honigstein, 1981). Recent movements have occurred along the south segment of the north-south-trending Arava fault south of the Amazyahu transverse fault (Zak and Freund, 1966). These strike-slip movements probably did not continue after Miocene along the main East fault of the Dead Sea, which is the north extension of the Arava wrench fault. In contrast, recent movements have been present along the north-northeast- trending Jordan or Dead Sea fault (Ben-Menahem et al., 1977, fig. 1). The movements extend south from east of Jericho in the north along the base of the west submarine slope of the sea and the elongate salt diapir of Mount Sedom as far as the Amazyahu fault in the south.

Today the wild boar (subspecies Sub scrofa lybica Gray, 1868) is the largest wild mammal found in Israel (Mendelssohn & Yom Tov 1999a). Sus scrofa has formed an integral part of the fauna of Israel since c.0.78 Mya, with the earliest skeletal remains derived from the Lower Palaeolithic site of Gesher Benot Ya’akov, Israel (Hooijer 1959; Geraads & Tchernov 1983). Remains of wild boar are commonly found in archaeological assemblages in this region (e.g. Davis 1982; Tchernov 1988), and according to 19th-century travellers, wild boar were abundant throughout Palestine, including the thickets of the Jordan river and the Dead Sea, and even extended into the arid regions of the northern Negev and Judean desert (Tristram 1866; Hart 1891; Bodenheimer 1958; Qumsiyeh 1996). However, during the period of the Mandate of Palestine (1923–48) the population size of wild boar was severely reduced by hunting, and as a consequence, their distribution was reduced to the Jordan valley, from the Hula Lake in the north to Sdom at the southern tip of the Dead Sea (Bodenheimer 1958; Mendelssohn & Yom-Tov 1999 a, 1999b). Since the creation of the State of Israel in 1948 they have been protected by legislation, which, coupled with the reduced numbers of predators, has resulted in a marked increase in their numbers. Nowadays, wild boar occupy most of their former habitats including the coastal region. The species has also been observed as far south as Nahal Besor in the northern Negev, but it has been proposed that these animals may represent hybrids of domestic pigs and wild boar (Mendelssohn & Yom-Tov 1999b). Four main concentrations of wild boar can be identified in Israel today: the Upper Galilee (especially in the national park of Mount Meiron), the Hula Nature Reserve, the Golan Heights, and Sdom. As shown in Table 12.1, these areas differ markedly in vegetation, altitude, and climate. A study of dental pathology in skeletal collections derived from these groups showed significant differences between the four areas (Horwitz & Davidowitz 1992). Specifically, the Sdom group was characterized by an unusually high frequency of hypodontia of the lower third incisor, indicative of inbreeding.

Late Cretaceous and Miocene collisions of the Arabian, Anatolian and Eurasian plates, as shown by widespread ophiolitic exposures along the suture, created favourable geological conditions for the formation of the surface and subsurface structures in the Gaziantep Basin, southeast Turkey. The late Cretaceous (Maastrichtian) emplacement of the Kocali–Karadut ophiolite complex induced subsidence in the northwestern zone of the Kastel Basin during the early Alpine Orogeny and influenced the structural evolution of the foreland area. The Dead Sea Fault, which originated in the Red Sea in Miocene time, propagated towards the northwest in the Suez Gulf and the north-northeast in southeast Turkey, and influenced the structural evolution of the Gaziantep Basin. These two major tectonic events produced many thrusts, thrust-related subsurface and surface anticlines, faults, fractures, flower structures and basaltic flows in the area. Geological and geophysical investigations indicate the existence of two important structural phases. The older structures were formed during the late Cretaceous movements, but they have been reactivated by latest Miocene tectonic activities with appearance of the Strands of the Dead Sea Fault in the sedimentary basin. The geothermal studies show also that, as a result of the Tertiary transgressions and volcanic activity, the northern and southern sectors of the Gaziantep Basin underwent differing subsidence and structural histories.

AbstractThe drilled Inter-Continental Drilling Project core at the deeps of the Dead Sea reveals thick sequences of halite deposits from the last interglacial period, reflecting prevailing arid conditions in the lake’s watershed. Here, we examine sequences of intercalating evaporates (halite or gypsum) and fine-detritus laminae and apply petrographic, micro-X-ray fluorescence, and statistical tools to establish in high-temporal resolution the hydroclimatic controls on the sedimentation in the last interglacial Dead Sea. The time series of the thickness of the best-recovered core sections of the layered halite, detritus, and gypsum reveals periodicities of ~11, 7–8, and 4–5 yr, pointing to a North Atlantic control and possibly solar influence on the hydrology of the Dead Sea watershed during the regionally arid period of the last interglacial period. Similar periodicities were detected in the last glacial and modern sedimentary sequences of the Dead Sea and other archives of the central Levant, indicating a persistent impact of the solar cycles on regional hydrology, possibly through the effects of the North Atlantic Oscillation.

The freshwater Lake Kinneret (Sea of Galilee) and the hypersaline Dead Sea are remnant lakes, evolved from ancient water bodies that filled the tectonic depressions along the Dead Sea Transform (DST) during the Neogene–Quartenary periods. We reconstructed the limnological history (level and composition) of Lake Kinneret during the past ∼40,000 years and compared it with the history of the contemporaneous Lake Lisan from the aspect of the regional and global climate history. The lake level reconstruction was achieved through a chronological and sedimentological investigation of exposed sedimentary sections in the Kinnarot basin trenches and cores drilled at the Ohalo II archeological site. Shoreline chronology was established by radiocarbon dating of organic remains and of Melanopsis shells.The major changes in Lake Kinneret level were synchronous with those of the southern Lake Lisan. Both lakes dropped significantly ∼42,000, ∼30,000, 23,800, and 13,000 yr ago and rose ∼39,000, 26,000, 5000, and 1600 yr ago. Between 26,000 and 24,000 yr ago, the lakes merged into a unified water body and lake level achieved its maximum stand of ∼170 m below mean sea level (m bsl). Nevertheless, the fresh and saline water properties of Lake Kinneret and Lake Lisan, respectively, have been preserved throughout the 40,000 years studied. Calcium carbonate was always deposited as calcite in Lake Kinneret and as aragonite in Lake Lisan–Dead Sea, indicating that the Dead Sea brine (which supports aragonite production) never reached or affected Lake Kinneret, even during the period of lake high stand and convergence. The synchronous level fluctuation of lakes Kinneret, Lisan, and the Holocene Dead Sea is consistent with the dominance of the Atlantic–Mediterranean rain system on the catchment of the basin and the regional hydrology. The major drops in Lake Kinneret–Lisan levels coincide with the timing of cold spells in the North Atlantic that caused a shut down of rains in the East Mediterranean and the lakes drainage area.
