通过分析云南省个旧市东区老厂东地段锡铜铅矿区区域及矿床地质特征，确定了该矿床的成矿模式为岩浆期后热液矿床和接触带交代的矽卡岩型硫化物矿床，并分析出矿区矿化主要受断裂构造和深部隐伏有燕山期花岗岩、印支期变玄武岩控制。%Mineral region of tin-copper-lead and geological features of mineral deposit are analyzed in east area of Lao Chang, Gejiu, Yunnan province. Metallogenic model of the mineral deposit is identified as later hydrothermal of magma period and skarn type of sulfide among contact zone. Also mineralization of mineral area is in the charge of faulted structure, deep concealed of granite in Yanshan epoch and basalts of Indosinian epoch.
