摘要
文章从水口山矿田所处大地构造背景及矿田构造岩浆作用分析入手,阐明了矿田内两大成岩成矿系列:Ⅰ与燕山中期中酸性侵入类有关的中温热液接触交代(夕卡岩)型铅锌铜银硫矿床,Ⅱ与燕山晚期英安质次火山—火山岩有关的浅成低温热液铅锌金银矿床。讨论了两者间的时空关系,分析了控矿因素,总结了矿床定位模式,并结合地物化遥资料进行了矿田内找矿远景区的评价。
Two series of magmatism and mineralization in the Shuikoushan orefleld are distinguished according to the analyses on tectonic setting and tectono - magmatism, including： （ 1 ） skarn - mesothermal Pb - Zn - Cu - Ag deposits related to the intermediate - acidic intrusions of the middle Yanshanian period; （2） epithermal Pb - Zn - Au - Ag deposits related to dacitic subvolcanic - volcanic rocks of the late Yanshanian period. The temporal and spatial relationships between the two series and the ore - controlling factors are discussed, and the localization modes summarized. The potential prospecting area are proposed and assessed based on comprehensive data of geology and geochemical - geophysical prospecting.
