| 摘 要： | 二朗评群蛇绿岩的形成环境是一具长期争议的问题，而此问题对于认识秦岭造由带的演化史具有重大的意义．本文通过对二朗坪群蛇绿岩中的重要组成部分细碧岩－石英角斑岩组俣的研究，认为：（１）弧后引张是形成该蛇绿岩的机制；（２）块状硫化物矿床与该蛇绿岩有着内在的联系．

| Abstract: | The formation environment of Erlangping group ophiolite has been argued for a long time, and it is impportant to realize the evolution history of Qinling orogenic belt.According to the study of spilite-Quartz Keratophyre association which consists of the main part of Erlangping group ophiolite, we suggest: (1) Back arc extension is the formation mechanism of the ophiolite; (2) There is internal relation between massive sulfide deposits and ophiolite. |
