In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

本文重点以老厂矿田中的接触带锡铜矿床和脉状矿床为研究对象，采用化学分析、ICP-MS、X射线粉晶衍射分析、电子探针等测试手段，对本区与成矿相关的基性-超基性火山岩、花岗岩、夕卡岩、电气石-石榴石等进行了系统的地质地球化学研究，研究表明：个旧矿区中三叠纪个旧组地层中的火山岩为钙碱性玄武岩-拉斑玄武岩系列，岩石为辉石-角闪石-长石-绿泥石-金云母组合；本区的花岗岩为过铝质花岗岩，主要与燕山期碰撞造山作用有关，锡多金属成矿与形成时代最晚、分异较好的花岗岩关系密切；本区夕卡岩中的有用共生组份随着夕卡岩类型及其矿物组合的不同具有明显的分带性。
