摘　　要：安徽宿州栏杆地区辉绿岩是含金刚石的主要载体岩石,而金刚石主要选获在辉绿岩捕虏体中。本文通过研究含矿辉绿岩捕虏体的地质特征,分析捕虏体中选获的金刚石特征,以及辉绿岩岩浆源区及构造背景,探讨了金刚石的成因。Diabase is the main diamond-carrying rock in the Langan area,Suzhou,Anhui Province and the diamond is mainly obtained from xenolith in the diabase by processing.Based on research of geological features of diamond-containing xenolith in the diabase,this paper analyzes the features of the diamond,the source of the diabase magma and tectonic background,and discusses the genesis of the diamond.
