“…Analysis of paleomagnetic data (see Figure 5) indicates that the central part of the GDRSP corresponding to the following regions: Eastern Taurides, Turkey [38], Central Lebanon [40], Cyprus [37], Northern Israel [41], Southern Israel [35] and Eastern Egypt [42] is characterized by counter-clockwise rotation (in [41] the clockwise rotation was also observed). The Western Caucasus (WC) is associated with the peripheral part of the GDRSP mainly exhibiting counter-clockwise rotation (e.g., [43] [44] [46]), whereas the Eastern Caucasus (EC) (Figure 4) located outside the GDRSP, primarily presents a clockwise rotation (e.g., [44] [47] [48] [97]).…”

Taurides [38] (Somalirhynchia-Septirhynchia) in these facies are very similar to those of the Ethiopian paleobiogeographical province in Saudi Arabia, Ethiopia, and Somalia [35]. Thus, the sedimentary deposits of the foreland of Northern Arabia and Eastern Nubia are tectonically discordantly joined with the allochthonic Mesozoic terrain belt ( Figure 5) rotated towards the Gondwana counterclockwise.…”

“…The axis of separation of the Western Caucasus (WC) and Eastern Caucasus (EC) zones-the Main East European Fault (MEEF) (e.g., [94] [95]); at present the MEEF is considered as a system of faults)-continues to the North within the Eastern European platform ( Figure 5 and Figure 7). This fault, however, does not continue to the southern analog of this structure, the Eastern Mediterranean Nubian Fault (EMNB) [16] [35] [65] (shifted relative to MEEF for 500 -600 km to the west), which is an axial fault of the GDRSP of the Mesozoic age ( Figure 5 and Figure 7).…”

In the Arabian-Northern African region, interaction of the Nubian, Arabian and Eurasian plates and many small tectonic units is conspicuous. In order to better understand this interaction, we use satellite derived gravity data (retracked to the Earth's surface) recognized now as a powerful tool for tectono-geodynamic zonation. We applied the polynomial approximation to the gravity data which indicated the presence of a large, deep ring structure in the eastern Mediterranean centered below the Island of Cyprus. Quantitative analysis of residual gravity anomaly provides an estimate of the deep anomalous body's upper edge at a depth of about 1700 km. Computations of the residual gravity anomalies for the lower mantle also indicate presence of anomalous sources. The GPS vector pattern coinciding with the gravity trend implies counter clockwise rotation of this structure. Independent analyses of the geoid isolines map and seismic tomography data support the existence of a deep anomaly. Paleomagnetic data analysis from the surrounding regions confirms a counter clockwise rotation. Numerous petrological, mineralogical, geodynamical and tectonic data suggest a relation between this deep structure and near-surface processes. This anomaly sheds light on a number of phenomena including the Cyprus gravity anomaly, counter clockwise rotation of the Mesozoic terrane belt and asymmetry of basins along continental transform faults.

“…This in turn might have generated the necessary conditions for the periodical generation of MTDs. The Late Barremian to early Aptian period is overall characterized by raising sea levels (Haq & Al‐Qahtani, ; Haq, ), facilitating accumulation space of the PST at this time (Eppelbaum & Katz, ).…”

The drowning of a siliciclastic shelf: insights into oceanographic reconstructions of the northern Arabian Platform during the Early Cretaceous

Barremian-Aptian sedimentary successions along the northern Arabian margin have been described as a transition from a siliciclastic to a carbonate-dominated marine environment, deposited upon a low-relief shelf or platform formed as a consequence of continuous regional subsidence. A long (360 m) core from northern Israel offers a unique look at this transition, providing valuable insights for the palaeoceanography, geometry and ventilation conditions that lead to Oceanic Anoxic Event 1 (OAE1) in this region. Results from high-resolution elemental, mineralogical, sedimentological and petrophysical analyses carried out revealed the emplacement of abundant mass-transport deposits (MTDs) during the Late Barremian and the Aptian. The transplanted units are characterized by fine grained calcareous shales with elevated organic matter, sulphur and iron contents. The scarcity or absence of bioturbation in the disturbed sequences provides a hint to the sediment/water interface conditions. However, a decrease in sulphur and iron occurring at the contact between the shales and the MTDs is explained as increased oxic conditions at the sediment-water interface as a result of turbulence and mixing associated with the descending sediment masses. Such recurrent events ventilation of the low-energy basinal environment during the Late Barremian and Aptian, predate the wide-scale establishment of OAE1 in the northern Arabian margin. Moreover, the identification of coarse-grained MTDs within deep-water calcareous sediments indicates a much steeper gradient of the northern Arabian margin, challenging previous studies.

An integrated analysis of several regional geological and geophysical factors allowed to select theMakhtesh Ramon area (northern Negev, Israel) feldspars, pyroxenes, magnetite, hematite, ilmenite, galenite, pyrite, limonite, mica, chromite, leucoxene, zircon, rutile, etc olivine, anatase and tourmaline (including black samples). These minerals do not rolled and oxidized that is an additional evidence of the neighboring occurrence of the indigenous rocks. Data of electronic microscopy show that the grains of (1) picroilmenite and (2) pyrope contain, respectively: (1) cobalt, chrome, magnesium and nickel and (2) chrome, magnesium and aluminum. This indicates that both picroilmenite and pyrope have the hyper-abyssal origin that also is an indicator of the possible occurring of diamondiferous pipes.
