کانی‌‌شناسی و شیمی کانی سرپانتینیت‌ها و متالیستونیت‌های افیولیت بیاضه (شمال شرق استان اصفهان)
The Bayazeh ophiolite, with probable Paleozoic age, is cropped out along the Bayazeh fault and located in the eastern margin of the Yazd block (Central Iran). In the field, this ophiolite consists of serpentinized peridotites, metagabbro, ultrabasic metamorphosed dikes, metapicrite, serpentinite and metalistvenite. Development of serpentinization process in the Bayazeh mantle peridotites has be...

Mantle peridotites are one of the most important rock units of Jandaq ophiolite that are affected by numerous,phases of dynamic and static serpentinization, and metamorphism. The main part of mantle peridotites is lherzolite. This ophiolitic association is covered by Paleozoic metamorphic rocks that are schist and marble. All olivines are changed to serpentine. Most of orthopyroxenes are b...
متن کاملChromespinel and Magnetite as Indicators for Recognition of Genesis and History of Serpentinites in Baft Ophiolite Mélange (Kerman Province in Iran)
Baft ophiolite mélange is a part of Naein-Baft ophiolite (southeast of Kerman province in Iran). Serpentinites from Baft ophiolite mélange contain different types of spinels such as chromite, chromespinel, ferritchromite and magnetite which can reveal different stages of evolution in host serpentinites. The compositions of Baft chromites show that they belong to podiform chromitites that may ha...

The study area forms part of the Zagros Zone. It is located on the NW of Piranshahr town, NW Iran. The study of altered peridotite clasts of the Creteceous conglomerate is the main subject of this research. They have polygenetic origins having calcite as the constituent cement. The size of clast is ranging from mm to cm including sedimentary and metamorphic rocks fragments, altered peridotites ...
