摘　　要：西(和)成(县)铅锌矿田秦岭型铅锌矿床主要有两种成因类型:热水沉积型及热水沉积改造型,热水沉积型主要受同生断裂与断陷滞流盆地控制;热水沉积改造型主要受礁硅岩套及同沉积褶皱控制。通过控矿因素的分析,在以后找矿过程中应注重岩性、岩相、地层厚度变化部位,与背斜伴生的向斜构造以及现有矿床的深部地段。Xicheng lead-zinc mine field QinLing lead-zinc mine bed mainly to have two kind of genetic types： The hot water deposit and the hot water deposit transformation, the hot water deposit with is broken mainly the singleness break falls the lagging current basin control; Hot water deposit transformation mainly reef quartzite set and with deposition fold control. Through controls the ore factor the analysis, should pay great attention glottological, the litchi fancies, and the stratum depth change spot in the later prospecting process, and with anticline associated syncline structure as well as existing ore deposit depth portion land sector.
