The Sinai Metamorphic Complexes from Rodinia Rifting to the Gondwana Collision
بدأت القصة بخسف حدث من حوالي ١٠٠٠ مليون سنة. هذا الخسف كان ناتج من انقسام قارة قديمة تسمي قارة الرودنيا. نتيجة للخسف ونقصان سمك القشرة الارضية بدأت الصخور الرسوبية تسخن بفعل حرارة وشاح الارض (اجزاء من هذة الصخور يمكن ان تجدها في وادي سعال بسيناء). الخسف اتسع مع الوقت وتحول…
Mineral stability at the mantle transition zone (in progress)
Corundum and amphibole-bearing ultramafics in Orlica-Śnieżnik Dome-SW Poland: from hydrous aluminum metasomatism in the mid- Saxothuringian Ocean to retrogressive metamorphism in the magmatic arc of the Variscan Orogeny (in progress)
Petrogenetic constraints on the origin and evolution of the Wadi Ghadir ophiolites, Eastern Desert, Egypt (in progress)
Pan-African tectono-thermal evolution of metamorphic complexes in Sinai: Transition from continental-arc collision to back-arc rifting in northern Gondwana (Submitted)
Abstract Amalgamation of supercontinents coincides with dramatic changes of the thermal structural of Earth’s lithosphere that can be observed as different mineral parageneses. Pan-African metamorphic complexes of the Sinai Peninsula (i.e. Feiran-Solaf, Taba and Kid) are studied here to reveal the complex tectono-thermal history that characterizes the amalgamation of the…
Early Ensimatic Stage of the Arabian-Nubian Shield (Submitted)
Abstract: The majority of geological investigations that deal with the Arabian-Nubian Shield (ANS) comply with the processes of ocean closure, subduction, orogenesis and crustal growth related to the assembly of Gondwanaland in the late Neoproterozoic. Otherwise, valuable current published discussions emphasize the development of the Arabian–Nubian Shield in the light…
