摘要
略阳─石泉构造带是一板块缝合带，经历了长期复杂的演化历史。现由不同时期、不同构造体制下的断裂构造系统，裹挟不同构造演化阶段的各类建造─蛇绿混杂岩、陆缘楔状体，岛孤岩浆岩及外来岩块等，共同组成了分隔秦岭、扬子地块的一个特殊边界地质体。
The tectonic belt of Lue Yang-Shi Quan is a plate stylolitic belt which has undergone a long and complex evolution history. This belt is the geological body between Qinling and Yangtze plate, which mainly consists of fault structure system formed in different periods. Ophiolitic hybrid rock, epicontinental wedge-shaped block, island arc magma, exotic block formed in different stages of tectonic evolution can also be found in this belt.
