摘　　要：桂阳县大坊矿区地处南岭东西向构造带东段北缘,位于耒(阳)-临(武)南北向构造带中段,与新华夏系的交汇部位。文章对大坊矿区地质特征和矿体特征进行详细分析的基础上,总结了控矿因素。研究认为:矿床成因为与酸-中酸性小侵入体有关的高-中温热液充填交代矿床。The Dafang mining area in Guiyang County is situated in the northern part of the eastern segment of the Nanling east-west structural belt,within the central region of the Leiyang-Linwu north-south structural belt,and intersects with the Cathaysian.This article provides a detailed analysis of the geological characteristics and ore body features in the Dafang mining area and identifies the key factors controlling mineral deposits.The study indicates that the formation of these deposits is closely related to the filling of high to intermediate-temperature hydrothermal fluids and alteration caused by acidic to mildly acidic small intrusive bodies.
