摘要
正岔铅锌矿床具有多源、多期、多阶段成矿的特点，成矿主要与燕山期花岗斑岩体有关。对矿床地质特征、同位素地球化学特征、成因机理等的研究认为：成矿物质具有双重来源———地层源与岩浆源，成矿水源为岩浆水和大气降水的混合、成矿热源为花岗斑岩浆活动，成因类型为层控矽卡岩型矿床。
The characteristics of formation of Jilin Zhengcha Pb-Zn deposit is of polygene,multistage and multiphase,which is related to Yanshan porphyry.After research on geological features,isotope geochemistry features and metalogenic mechanism,the writer believes that metallogenic substance has double sources-strata and magma.Metallogenic water sources are the mixture of magma and precipitate water;Metallogenic heat sources are movement of porphyry;Metallogenic type belongs to stratabound skarn ore deposit.
