通过井下详细的勘查和显微镜下光薄片的鉴定，对龙湾铅锌矿床矿石特征进行了系统的研究，总结了该矿床典型的矿石组构特征。矿石构造主要为浸染状构造、条带状构造、团块状构造、脉状构造、网脉状构造、斑杂状构造等。矿石结构主要有结晶粒状结构、交代溶蚀结构、固溶体分离结构、压碎结构、填隙结构、揉皱结构等。根据矿物的组构特征及金属矿物和脉石矿物组合、结构构造、交插关系等特征分析，将该矿床划分为三个期次和六个阶段，初步认为该矿床属于沉积-岩浆热液叠加改造型多金属矿床。

Through detailed downhole exploration and microscopic identification of polished thin section,this paper conducted systematic research on ore characteristics of Longwan Pb-Zn deposit,and summarized the typical fabric characteristics of ores.The ore occurred as disseminated,banded,lumpy,veined,stockwork and taxitic in form.The ore textures mainly include crystalline granular texture,metasomatic corrosion tex-ture,solid solution unmixing texture,pressure texture,interstitial structure and crumpled texture.Based on the characteristic analysis on fabric characteristics of minerals,association of metal mineral and gangue mineral,texture and structure,and interlace relationship,the author divided the deposit into three phases and six stages.It is preliminarily deemed that the deposit is a sedimentary-magmatic hydrothermal superim-posed reformed type deposit.
