The Dinaride Ophiolite Belt formed from the Jurassic part of Neotethys. investigated Ozren ophiolite complex in Bosnia and Herzegovina consists peridotites, plagioclase plagiogranites, troctolites other gabbroic rocks, fewer basalts. Lherzolites harzburgites contain corroded ortho- clinopyroxene1 porphyroclasts enclosed olivine matrix. boundaries between aggregates pyroxene1 spinel1 are infille...
The Trans-European Suture Zone (TESZ) is the most important and extensive continental suture in Europe, marking edge of East European Craton (EEC), from North Sea to Black Sea. It corresponds significant changes surface geology deep crustal structure, evident seismic, gravitational magnetic studies. However, TESZ disappears beneath Eastern Carpathians accretionary nappes Neotethys ophiolites, t...
Upper Triassic sedimentary systems of both the Arabian Plate and Germanic Basin reveal climate- plate tectonic-forced effects through certain time-intervals experienced by architectural elements, lithofacies types, unconformities, flash flood deposits, maximum flooding surfaces/sequence boundary (MFS/SB), mineralogy, isotope anomalies. Further, Moon recession changes Earth’s rotation velocity (...
The Naghadeh metamorphic complex at the West-Azerbaijan Province is located at termination of the NW Sanandaj-Sirjan Zone. Major varieties of the metamorphic rocks in this area are: amphibolites, greenschists, marbles and metaperidotites. The metaperidotites are classified into two groups, serpentinised metaperidotites and serpentinites. Orthopyroxene, clinopyroxene, olivine and spinel are the ...
The Kahrizbeyg pluton is located northwest of Iran in Central Iran zone. It is emplaced into the Cretaceous limestones in which contact metamorphism has happened. Meanwhile, rock fragments of this pluton are found in conglomerate units of Early Oligocene Lower Red Formation. Therefore, the relative age of pluton is between Cretaceous and Oligocene. The Kahrizbeyg pluton consists of granite and ...
The Takht-e-Soleyman complex is formed from various rock types including metapelites, metabasites and marbles which are metamorphosed under green schist through amphibolite to granulite facies. The amphibolites have been melted partially under high temperatures and mafic migmatites are formed in this regard. The pick metamorphic minerals of garnet amphibolites have been completely replaced by t...
The major syenitic bodies of Iran are spread on northwestern part, East Azerbaijan Province, which belong to late Eocene, early Oligocene magmatisem. Abbasabbad–Bashkand pluton is one of these intrusions, which is located as some minor and autonomous bodies in western side of the main Bozghush nepheline syenite pluton. Porphyritic, microgranular and porphyritic microgranular are common textures...
Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...
Abstract Anatolia is characterised by a complex geodynamic evolution, mirrored wide spectrum of magmatism. Here, we investigated the timing and geochemical/isotopic characters Miocene to Pliocene volcanism Sivas–Malatya Region (Central Eastern Anatolia), its relationships with local regional tectonics. Na-alkaline basaltic lavas were emplaced during middle at Sivas (16.7–13.1 Ma), in North, whi...
