摘　　要：蛇绿岩以岩块形式镶嵌于甘孜—理塘结合带内,经拼合可见一个较为完整的蛇绿岩套。形成于洋中脊环境,火山岩显示张裂速率大于3cm.a-1,形成时代为晚三叠世。The ophiolite is massive and mosaic-like in the Ganzi—Litang conjunction zone.According to the combination of them,we can see a complete ophiolite suite.The ophiolite is formed in the mid-oceanic-ridge environment.The volcanic rock shows that the extension rate is over 3cm.a-1 The formation period of it is Late Triassic.

关 键 词：蛇绿岩 张裂速率 晚三叠世 洋中脊环境 甘孜—理塘结合带
