40Ar/39Ar dating of the Aptian–Albian igneous rocks in Makhtesh Ramon (Negev, Israel) and its stratigraphic implications

Newly developed paleomagnetic map of the EasternmostMediterranean joined with tectono-structural analysis unmaskgeodynamic history of this region

“…Taking into account the aforementioned considerations, the considered block corresponds to Jalal hyperzone (Table 1 and Figure 7). This proposition is supported by development of mainly directly magnetized Aptian and Albian traps of Makhtesh Ramon [73]. These traps are also developed to the south of the proposed Jalal hyperzone within the Gulf of Suez [122] that con rms active displacement of the oceanic crust to west of the Kiama hyperzone in the Middle Cretaceous.…”

“…Hermon). Data on borehole sections and outcroppings were taken from numerous publications and reports [9,11,18,33,[60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75]. Among the employed materials were geological maps of Israel [76], Jordan [77], Egypt [72] and photomaps of Israel and adjacent areas [78].…”

“…Among the employed materials were geological maps of Israel [76], Jordan [77], Egypt [72] and photomaps of Israel and adjacent areas [78]. Radiometric data displayed in [22,73,[79][80][81][82][83] were explored. Available paleontological data for the region under study [9,18,[84][85][86] were studied.…”

Makhtesh Ramon Complex Deposit (Southern Israel) – A Window to the Upper Mantle

“…Larson (1995) termed this epoch the Middle Cretaceous maximum in the development of upper mantle hot spots and associated it with high development of diamond-bearing kimberlites during the Mid-Cretaceous. In the Makhtesh Ramon area, this stage is reflected in central-type volcanoes composed of lava flows, eruptive breccia, and tuffs that suggest wide development of explosive volcanism in the Middle Cretaceous (Lang and Steinitz, 1989;Segev et al, 2005). Chang and Lee (2011) presented tectonic map with three large mantle plumes in the Near and Middle East, and one of the plumes completely covers the makhteshim family location.…”

“…It should be noted that the Gissar paleomagnetic zone is by numerous approximately equivalent alternation of direct and reverse polarities (this fact must be taken into account by magnetic anomalies qualitative and quantitative examination). Eppelbaum and Katz, 2015, with small modifications) ( Garfunkel and Katz (1967), Zak (1968), Baer and Reches (1991), Baer (1993), Baer et al (1995), Sneh et al (1997)), (5) radiometric age of magmatic rocks (after Lang and Steinitz, 1989;Segev, 2000;Segev et al, 2005), (6) faults; paleomagnetic zonation within the magmatic complexes (7)(8)(9)(10): (7) Illawarra, (8) Omolon, (9) Gissar, (10) Jalal…”
