郭家沟铅锌矿床矿化特征

摘要

郭家沟隐伏大型铅锌矿床为热水沉积-改造型矿床，以后期热液改造成矿作用为主。选择Ⅰ＃矿体顶板与千枚岩和灰岩的接触带为2个标志层，通过标志层在构造作用下的形变来反应控矿褶皱的形态特征。在分析矿床地质特征的基础上，探讨了矿床矿化分布规律，并对控矿因素和找矿方向进行了讨论，为区内找矿工作提供参考。%Guojiagou concealed large lead-zinc deposit is a sedimentation-hydrothermal reworked deposit,the main mineralization is the late hydrothermal mineralization.The roof and the contaction with phyllite and limestone of 1 #orebody are regarded as two marker beds.Based on analyzing the geological characteristics of the orebody of Guijiagou lead-zine deposit,the distribution regularity of mineralization of the orebody are discussed,besides that,the ore-controlling factors and prospecting direction are also dis-cussed so as to provide reference for the prospecting work in research area.
