Yarlung Zangbo suture is one of intra-continental suture zones in Gondwana plate and represent material residual for neo-Tethyan ocean close. The ophiolite in the suture zone is distributing along the Yarlung Zangbu River, forming the largest ophiolite belt in China, which is composed of prodotite, basic-ultrabasic cumulate complexes, dolerite, silicic rock and basic lava etc. in which the peridotite as the main component of the ophiolite had undergone strong deformation with dolerite intruded along faults. There is podiform Chromite in the peridotite with diabase developed locally and plagioclasite obducted up on the midupper part of accumulate. Petrology, geochemistry and isotopic data of peridotite in the ophiolite were studied to discern the relationship among the ophiolite and chromite metallogenesis and the tectonic settings.
