“…-Giant cores were made on basalt and basanite (henceforth basalt) slabs that were extracted at some distance from GBY at unknown quarry sites in the volcanic bedrock in the vicinity of the site [55]. Quarrying the basalt slabs necessitated in-depth knowledge of the characteristics of the basaltic bedrock.…”

The Acheulian presence in the Dead Sea Rift and its environs is characterized by the discontinuity of its cultural manifestations. Nevertheless, the long stratigraphic sequences of the Acheulian Technocomplex provide a unique opportunity for synergetic examination along a temporal trajectory. Hominin cognitive and cultural behaviour are studied at Gesher Benot Ya , aqov through analyses of lithic, palaeontological and palaeobotanical assemblages, as well as the Early -Middle Pleistocene environment, ecology and climate. The study attempts to reconstruct reduction sequences of some major artefact groups at the site, which include raw material acquisition, production, technology, typology, usage and discard. Experimental archaeology illustrates artefact mobility on the palaeolandscape. Strategies of biomass-exploitation are studied in detail, with other aspects yielding additional information on hominin subsistence and adaptive responses to their environment. The cultural marker of fire and the spatial association of selected categories of finds are integrated in the general synthesis, allowing reconstruction of the cultural and cognitive realm of Acheulian hominins. The synthesis attempts to reassess the abilities, social structure, subsistence and adaptability to the changing environment of hominins in the Levantine Corridor.

“…However, timing of initiation of the transpressive phase in Lebanon and Syria is often reported to the entire Pliocene -Pleistocene period. Further south, basaltic units dated from the early Pleistocene onwards are found exclusively east of the Dead Sea fault axis (Weinstein et al, 2006). One of these units, the 1.5-0.5 Ma old Hazbani basalt (Sneh and Weinberger, 2003) flowed southward from its source in southern Lebanon along the Dead Sea fault axis towards the subsiding Hula basin (Heimann, 1990).…”

The isotopic composition of mafic small-volume intra-plate magmatism constrains the compositions of the sub-continental mantle sources. The Nd, Pb, and Sr isotope signatures of widespread late Mesozoic to Quaternary intra-plate magmatism in NE Africa (Sudan, South Egypt) are surprisingly uniform and indicate the presence of a high-µ (µ= 238 U/ 204 Pb) source in the mantle. The rocks are characterized by small ranges in the initial isotopic composition of Nd, Pb, and Sr and most samples fall within ε Nd ca 3 to 6, 206 Sr/ 86 Sr ca. 0.7028 to 0.7034. We interpret this reservoir as lithospheric mantle that formed beneath the Pan-African orogens and magmatic arcs from asthenospheric mantle, which was enriched in trace elements (U, Th, and light REE). Combining our new data set with published data of intra-plate magmatic rocks from the Arabian plate indicates two compositionally different domains of lithospheric mantle in NE-Africa -Arabia. The two domains are spatially related to the subdivision of the Pan-African orogen into a western section dominated by reworked cratonic basement (NEAfrica; high-µ lithospheric mantle) and an eastern section dominated by juvenile Pan-African basement (easternmost NE-Africa and Arabia; moderate µ lithospheric mantle). The compositions of the Pan-African lithospheric mantle and the MORB-type mantle of the Red Sea and Gulf of Aden spreading centers could explain the Nd-Pb-Sr isotopic compositions of the most pristine Afar flood basalts in Yemen and Ethiopia by mixtures of the isotopic composition of regional lithospheric and asthenospheric sources.
