| 摘 要： | 已有研究实例阐明了蛇绿岩产出的构造环境及构造侵位机制的多样性 ,其中发育完整的蛇绿岩套具有与现代大洋岩石圈剖面相似的四层结构模式 ,它们形成于洋中脊扩张构造环境。由于构造运动使蛇绿岩套肢解 ,构造侵位于大陆造山带缝合线地带 ,沿断裂构造以构造岩片和构造混杂岩产出。蛇绿岩提供了洋壳形成和破坏的重要证据 ,蛇绿岩带或古缝合线是确定造山带中古洋盆存在及陆块边界的直接标志

| Abstract: | Complete developmental ophiolitic suites have a sight of typical four layered textures, which shows similarities to nowadays oceanic crust. They are formed in an extend environment by the mid oceanic ridge. Because of tectogenesis make for ophiolitic suites dismember and tectonic emplacement in to the Continental suture zone. Along the faults zones ophiolitic mass occurred in the form of tectonic shect and tectonic melange. Ophiolite give main evidence for the oceanic crust formation and break. Ophiolite belt or paleo suture line has a direct mark, which defined paleo oceanic basin in the orogenic belt and defined block of continet block |
