摘　　要：安县高川以北的黑湾辉绿岩分布于安县水磨沟一带,属于印支-燕山期。通过辉绿岩群的最高产出层位和形成于非造山性伸展构造环境的幔源岩浆经主元素、微量元素、稀土元素特征分析结果,认为该岩体属于裂谷型幔源岩浆沿着断裂带上侵并与陆壳混染侵位形成,区内辉绿岩形成板内构造环境,属于大陆裂谷作用产物。The diabase diabase in the north of Gao Chuan is distributed in the Shuimogou area of an County,belonging to Indo Yanshan epoch.The highest output layer and diabase group formed in anorogenic extensional tectonic environment of the mantle derived magma results that the rock belongs to the rift type mantle magma intruded along the fault zone and crustal contamination emplaced
