It is suggested therefore that the extensional direction evolution was controlled by the oceanic motion and the craton destruction took place under a back-arc spreading setting.

The eastward or southeastward mantle flow resulting from the collision of IndiaEurasia probably pushed rollback of slabs east and southeast to east Asian continent, further causing back arc spreading.

This paper discusses the feature of geology, lithogeochemical of this ophiolitic belt, so the ophiolite is produced from near the back-arc basin spreading ridge.
