摘要
会理铅锌矿床由于受到辉绿岩墙（脉）侵入和北西－南东向Ｆ３断裂的影响和破坏，以Ｆ３断裂为界，划分为东部矿体和西部矿体两部分．矿体东西方向长２８３ｍ，平均水平厚６９４ｍ，东厚西薄，东富西贫，呈楔型，向下呈简单分枝．东部分布有辉绿岩墙（脉）出露，并具有一定的矿化现象．因此，对于东西部两矿体是否是同源？矿源是地层源，还是岩浆源，或其它类型的矿源？控矿因素是地层，还是岩浆，或断裂？长期以来，对上述疑问众说纷纭．本文基于对Ｆ３断裂空间展布特征和立体模拟的基础上，按东西部划分不同的矿化信息，通过东西成矿元素差异性定量分析和研究后，认为地层源→岩浆侵入强改造→有利构造空间就位形成富矿体→Ｆ３断裂破坏矿体，东、西矿体是同源。
Because of the influence and destruction of diabase veindike intrusive and the F 3 fault of NW-SE,HuiLi Pb-Zn deposit is divided along F 3 into the east orebody and the west orebody.The orebodys length is 283 metres in east～west direction and the average thickness is 69 4 metres.The orebodys thickness and Pb-Zn content is thicker and higher in the east than in the west. Its shape takes after triangle and is branches of orebody in the depths.There is the distribute of intrusive diabse veindike with some degree mineralization in the east,So,whether the two orebodies are homelogous,its source is the stratum,the magma or other ore soures;the control factor is the stratum,the magma or the fault.All these questions have been discussed for a long time.On the basis of research on the characteristics of spatial exhibit and three dimensional simulator of F 3s distribution,dividing into the different mineralized infomation on the east orebody and west orebody,after the quantity analysis and research of the different informations between the two orebodies,the result is regarded as homelogue stratum→the foreible transform of the instrusive magma→the shoot takes shape when the orebearing solutions are entered into favourable tectnic space→the orebody is destroyed by F 3.So,the east and west orebodies are one homologous orebody.
