New geochronological data and published structural and stratigraphic data show that two distinctly different ophiolitic assemblages formed in general proximity to one another at nearly the same time and were subsequently imbricated along a regional thrust zone. The Josephine ophiolite constitutes a complete oceanic crust and upper mantle sequence which lies within the western Jurassic belt of t...

introduction khoy ophiolite at the global scale is in the middle part of the alp-himalaya orogenic belt and it is extended over 3900 km2 which indicates remnant neotethys oceanic lithosphere in the mesozoic era (kananian et al., 2010). in this paper, in addition to a review of previous investigations about khoy ophiolite, we will try to determine the nature and kind of minerals, origin and part...
