| 摘 要： | 习水县桑木场铅锌矿,容矿层为震旦系灯影组白云岩,属于局限台地相的碳酸盐盆地;铅锌矿受断层与裂隙控制,属于开放式空隙充填,矿石与容矿层呈脉状、网脉状接触。矿石矿物为闪锌矿及方铅矿,脉石矿物为重晶石、方解石、白云石、萤石、黄铁矿及石英。样品表现出两期成矿特征,根据矿物穿插关系可判定与流体活动相关的矿物生成顺序。本文结合习水县桑木场区域地质特征及样品岩相学、矿相学特征,初步判定研究区铅锌矿属于密西西比河谷型(MVT)铅锌矿,并以此典型矿床的成矿模式为指导,尝试在研究区内寻找较大型铅锌矿床。

| Abstract: | A batch of lead-zinc deposit samples are collected from Sangmuchang, Xishui County. They are produced in a certain horizon called the restricted platform in the sedimentary rock basin. The deposits are hosted in Late Proterozoic, especially in dolostone and formed by open-void filling. Collected by faults and fracture, lead-zinc mines have shown discordant, for instance phlebitic and diktyonitic and the characteristic of post-metallogenic. Lead-zinc mines consist of metal mineral and gangue mineral. In upwards, they are(1)sphalerite, galena and pyrite, (2)dolomite, barite, calcite, fluorite and quartz. This paper combines the characteristic of regional geology, petrography and mineragraphy. Preliminary determination of lead-zinc mines in the study area belong to Mississippi Valley-type(MVT) lead-zinc deposits. Following this pattern, we will look for others mineral deposits in our study area. |
