the upper cretaceous ganj complex, a part of the jazmurian ophiolitic belt, is located on the western boundary of jazmurian depression and separated from kahnuj ophiolitic complex by north-south trending jiroft fault. the complex consists of lava flows, pillow lavas, acidic plutonic and sedimentary rocks which are intruded by northwest-southeast trending dykes. it does not resemble a classical ...
the kahnuj ophiolitic complex, a part of the jazmurian ophiolitic belt, is located on the western boundary of the jazmurian depression and is bounded by two major fault systems. there is a well-preserved, ophiolite pseudostratigraphy of early cretaceous to early palaeocene age and has a bearing on the mesozoic development of southeastern part of iran and adjacent region. the kahnuj ophiolitic c...

We suggest a new explanation for the presence of crustally derived zircons in the upper-mantle rocks of ophiolitic complexes, as an alternative to subduction-related models. Integrated isotopic (U-Pb, Hf, and O isotopes) and trace-element data for zircons from the Tumut ophiolitic complex (southeast Australia) indicate that these grains are related to granitic magmatism and were introduced into...
Ophiolitic rocks in the southeastern part of the Zagros Orogenic Belt can be separated from southwest to northeast, into two groups: the Neyriz ophiolites and the Naien–Shahrebabak–Baft ophiolites. The southeast sector of Sanandaj-Sirjan wasdelimited by the two nearly synchronous ophiolitic belts in its southwestern and northeastern margins. In this study, new ophiolitic formation models were u...
Ophiolitic belt of Northern Sabzevar is invaded by basic, intermediate and acidic post-ophiolitic magmtism as dome, dyke and cone. Microscopically, the texture of the studied samples is porphyric and trachytic. Phenocryst mostly consists of amphibole, feldspar and clinopyroxene. All researchers that have investigated basic to acidic post ophiolitic magmatism of northern Sabzevar have consensus ...
