The Kermanshah ophiolite complex is a part of the Mediterranean–Zagros–Oman Tethyan ophiolites, located in the structural–tectonic zone of western Iran in the northern part of the Zagros main thrust. Doleritic sheeted dykes are well exposed within the ophiolite in the south of Sahneh. These dykes contain high MgO, Na2O, low TiO2 (2O5, and K2O contents, and high FeOt/MgO and LILE/HFSE ratios. Th...

In this paper, we introduce two different notions of generalized supra soft sets namely supra A--soft sets and supra soft locally closed sets in supra soft topological spaces, which are weak forms of supra open soft sets and discuss their relationships with each other and other supra open soft sets [{it International Journal of Mathematical Trends and Technology} (IJMTT), (2014) Vol. 9 (1):37--...

The Cubito-Moura Unit is a high-P metamorphic succession that occurs in the southern part of Ossa-Morena Complex (SW Iberian Massif). It includes series metasedimentary, metafelsic and metamafic rocks affected by high-P, low to intermediate-T event during Late Devonian times. Geochemistry metabasic reveals generation protoliths occurred supra-subduction zone setting Ediacaran Early Ordovician t...

Two main types of subduction zones can be distinguished: (1) those where the subduction hinge migrates away from the upper plate; and (2) those in which the subduction hinge migrates toward the upper plate. Apart from a few exceptions, this distinction seems to apply particularly for W-directed subduction zones and Eor NE-directed subduction zones, respectively. Moreover, the rate of subduction...

Mantle peridotites exposed in south Jazmourian comprise of lherzolite and porphyroclastic Cpx-bearing harzburgite in the lower part with chromitite lenses in the upper parts. Petrography and microprobe studies shows evidence of melt-peridotite interactions; post melting processes and subsolidus interactions, which has been associated with appearance of two generations of deformed primary pyroxe...

The mantle rocks from Kadaboura and Madara areas represent sections of dismembered ophiolitic complexes developed during the Neoproterozoic in Eastern Desert Egypt, which is located northwestern corner Arabian–Nubian Shield. comprise serpentinites serpentinized dunites, whereas those consist pyroxenites.Despite serpentinization studied rocks, few relicts primary chromite, olivine pyroxene are p...

Historic earthquake sequences on subduction zones that are similar to the Cascadia subduction zone are used to hypothesize the nature of shallow subduction earthquakes that might occur in the northwestern United States. Based on systematic comparisons of several physical characteristics, including physiography and seismicity, subduction zones that are deemed most similar to the Cascadia subduct...

The classic Neotethyan Ankara Melange formed within the Triassic-Eocene İzmir-Ankara-Erzincan ocean (‘N Neotethys’), bordered in central Anatolia by Kırşehir and Tauride-Anatolide continental units to south discontinuous Sakarya continent northwest. Farther north, separate Intra-Pontide probably remained partly open until early Cenozoic. developed via phases of intra-oceanic accretion (mainly p...
