摘　　要：Objective Discovery of Songduo eclogites exposed in southern Tibet has attracted wide attention from geologists.The recently completed regional geological surveys show that a lithotectonic belt extends at least 100 km from Zhikong in the west to Songduo in the east and is mainly composed of oceanic fragments such as eclogites,blueschists,ophiolites and oceanic island assemblages,with their associated arc igneous and metasedimentary rocks.This is referred to hereafter as the Zhikong-Songduo(ZS)subduction complex.
