Abstract:
      For first time, eclogitic rocks commonly with MORB-nature had found in a part of structural zone of Sanandaj-Sirjan, northern Shahrekord and 120km western Isfahan and 50 km of main thrust zone. Mineralogical studies according to EMP analysis and microscopic evidences show that these rocks contain omphacite, garnet, magnesiotaramite, barroisite, phengite, zoisite, rutile, magnetite, pyrite, and quartz ? kyanite. These rocks are group C eclogite on the base composition of garnet. C ? Group eclogite are belonged to subduction zone.
