摘　　要：运用构造解析方法,遵循共轭节理配套原则对核桃坪铅锌矿区的节理进行逐步分析,该区节理主要分为5组,共配成2套共轭节理,分属近南北向,东西向2个构造期次。据此推断该区节理的形成、发育先后受到该区近南北向和东西向构造期构造应力场作用的影响和制约。同时也很好的从小尺度构造角度反映了矿区主控矿断裂F1的演化。Abstract ： Following the conjugate jointing necessary principle, the structure analysis method was used t oanalyze the Hetaoping Pb-Zn deposit jointing gradually. The jointing mainly divides into 5 groups, altogether matches 2 set of conjugate jointings. There are two tectonic successions from north to south and from east to west. According to the above the inference jointing＇s formation and the growth receive this area near north and south successively to with the thing to the structure time Tectonic stress field function influence and the restriction. The evolution of major faults F1 fault belt have been responded in Hetaoping deposit.
