متن کاملTectonic evolution of the Khoy ophiolitic complex, NW Iran
The Khoy Ophiolitic Complex (KOC) as a part of Tethyan, Izmir-Ankara- Erzincan and Bitlis-Zagros sutures of South East (SE) Turkey is broadly exposed around Khoy region (NW Iran). This complex comprises dismembered fragments of mantle lithosphere, obducted oceanic lithosphere and parts of volcanic arc remnants. The Khoy Ophiolitic Complex can be structurally divided into two major eastern and w...
متن کاملUsing secondary minerals in Sahneh ophiolitic complex, west Iran
Kermanshah ophiolite is an extremely crushed ophiolitic complex in which a complete ophiolitic sequence is not observed. Gabbros, deloritc dikes and mostly serpentinized peridotites are among the most important constituents of these ophiolitic set. Pridotites existing in the study area are of metamorphosized types that have been severely affected by the hydrothermal solutions due to their extre...
متن کاملPlatinum-Group Element Geochemistry in Podiform Chromitites and Associated Peridotites of the Precambrian Ophiolite, Eastern Desert, Egypt
The ultramafic portions of the Proterozoic ophiolite, Eastern Desert, Egypt, contain significant chromitite concentrations that are mainly located in the central and southern parts of the Eastern Desert as small and irregular bodies within a fully serpentinized dunite and harzburgite. Chromitite spinel exhibits a wide range of composition from high Cr to high Al varieties. The Cr# of chromian s...

Niabad-Qalaje ophiolitic complex is part of Sarvabad ophiolites in Kurdistan that exposed in northwest of Iran and the north of Kermanshah Ophiolites. The complex located in north of Zagros orogeny, consists of lens form, tectonically dismembered ophiolitic sequences located along the main Zagros trust. The ultramafic part includes serpentinized dunite and wherlite, serpentinite and chromitite ...
