| Abstract: | The Raka ophiolite is located in the middle section of the plate suture zone in the Yarlung Zangbo region, Tibet. It is suggested
that the genesis of the ophiolite is similar to that of non-typic MORB in a marginal ocean basin through field geological
investigation, lithogeochemical analysis and synthetical comparison. It is concluded that the ophiolite in this region may
be relics of the subducted oceanic lithosphere in the Neo-Tethys period.
