Thus, they might be derived from a back - arc basin with an archipelagic system in paleo - tethys, instead of a large ocean basin. the isotopic geochemistry shows that the jinshajiang ophiolitic melange has higher e nd ( t ) values ( + 7. 42 - + 5. 44 ), suggesting that it may be derived from a lree depleted mantle source without significant contamination by the continental crust, but affected slightly by a fluid from a subducted ocean crust

同位素地球化學研究表明，金沙江蛇綠混雜巖具有較高的_ （ nd ） （ t ）值（ + 7 . 42 + 5 . 44 ）暗示蛇綠巖來源於lree長期較虧損的地幔源，演化過程中沒有受到陸源物質的明顯混染，而主要受到少量俯沖洋殼析出流體的影響。

Combining the isotope geochronological results with the fieldwork observations, we could draw some conclusions as follows : the kunlun - bayan har terranes experienced the subduction of oceanic crust and collision somewhat earlier than the bayan har - qiangtang terranes, with only a very short interval in between and even the collisions overlapped partially in time
