摘　　要：本文探讨了江西茅排金矿区范围内广泛分布的煌斑岩基本特征及其与金矿化的关系.根据野外观察及室内分析结果,确定了本区煌斑岩的类型、矿物成分、岩石化学、微量元素及稀土元素和金含量,并讨论了煌斑岩与茅排金矿床燕山期矿化作用的关系.In this paper, the basic characteristics of lamprophyre distributed widely in the area of Maopai Gold Field, Jiangxi Province and its relationship with gold mineralization are studied. Based on the results obtained from field obser ation and indoor analysis, the type, composition and petrology of lampro-phyre in this area and the trace elements, rare-earths element and gold contained in it are ascertained.Furthermore, the relation between lamprophyre and the mineralization of Yanshanian stage of Maopai Gold Deposit are discussed.
