摘　　要：本文介绍了铅锌银矿矿床的概况,包括其地层、地质构造、岩浆岩与围岩蚀变、矿床特征和矿体特征等方面。接着,文章对成矿温度、成矿流体来源、成矿物质来源和成矿年代等方面进行了分析。通过分析得出,矿床主要分布在石灰岩、页岩和砂岩中,成矿温度较高,成矿流体多来源于地下热水,成矿物质多来自围岩和深部地壳物质。此外,地质构造和岩浆岩与围岩蚀变也是矿床形成的重要因素。以上结论对于理解铅锌银矿床的形成机制、指导矿产勘探和开采具有重要意义。This article introduces the overview of lead zinc silver deposits,including their stratigraphy,geological structure,magmatic rock and surrounding rock alteration,deposit characteristics,and ore body characteristics.Subsequently,the article analyzed factors such as ore-forming temperature,ore-forming fluid sources,ore-forming material sources,and ore-forming age.Through analysis,it can be concluded that the ore deposits are mainly distributed in limestone,shale,and sandstone,with high ore-forming temperatures.The ore-forming fluids mostly come from underground hot water,and the ore-forming materials mostly come from surrounding rocks and deep crustal materials.In addition,geological structure and alteration of magmatic rocks and surrounding rocks are also important factors in the formation of mineral deposits.The above conclusions are of great significance for understanding the formation mechanism of lead zinc silver deposits and guiding mineral exploration and mining.
