| Abstract: | Geological,petrographical and geochemical characteristics of Garze-Litang ophiolite melange zone are summarized systimatically.This ophiolite melange suite is composed of metaperidotite,cumulate,sheeted dike,pillow basalt,massive basalt and radiolarite.The petrographic and geochmical characteristics indicate that the ophiolite formed in a sea floor spreading environment.The ophiolite melange zone represents forearc melange facies of the Yidun collision orogens. |

| Keywords: | ophiolite ophiolite melange zone forearc melange facies |
