Based on the geological,stratigraphic and geochemical characteristics of the ophiolitic melange,island-arc and rift volcanic rocks from the Jinshajiang zone,an archipelagic tectonic model with multi-rift and multi-subduction is proposed to explain the evolution of Jinshajiang Paleo-tethys.
本文主要研究了金沙江带的蛇绿混杂岩、岛弧火山岩和裂谷火山岩的地质、地层和地球化学特征并对金沙江古特提斯演化模式提出了多次裂开、多次俯冲的多岛洋体系模式。

It proves that the Jinshajiang suture zone could not have formed the main suture zone in the Paleo-Tethys domain.
因此，金沙江带不能作为古特提斯域的主缝合带。
This discovery has great significance for the understanding the process of the ocean-land transformation of the Paleo-Tethys.
这一发现对认识古特提斯洋-陆转化过程具有重要意义。
All the eclogite samples with the feature of both E-MORB and OIB indicate a plume-ridge interaction or hotspot-ridge interaction during the evolution process of Paleo-Tethys.
样品同时具备E-MORB和OIB的特征，说明古特提斯洋在漫长的演化过程中可能存在地幔柱岩浆和正常洋中脊亏损地幔岩浆的相互作用。
