摘要
苏家沟铅锌矿床位于华北准地台东北部之辽东台背斜,营口-宽甸古隆起的北缘草河口复向斜北翼之辽东裂谷成矿带中。为揭示该地区铅锌等多金属成矿规律和控矿因素,从区域地质背景、矿床地质特征及控矿因素分析等几个方面探讨了苏家沟铅锌矿的矿床成因,通过分析初步认为,该矿床属沉积变质-热液叠加再造型层控铅锌矿床,成矿物质主要来自地层,北东-北北东向断裂控制铅锌矿体的空间展布,背斜轴与断裂构造的交汇部是成矿的有利部位,兰花岭花岗岩体对铅锌矿质的活化转移和富集提供了热动力作用。
Sujiagou lead and zinc deposit locates in the palaeohigh Yingkou-- Kuandian metallogenic belt of the rift valley in the eastern and southern parts of Liaoning province, north wing of the synclinorium at the north of Caohekou, and the anteklise of northeast paraplatform in North China. In order to reveal the multi--metal ore--forming rules and ore--controlling factors in this region, the genesis of mineral deposit of Sujiagou lead and zinc deposit is discussed from several aspects, including the geological background, ore--deposit geologic features, ore--controlling factors, etc. It is considered through preliminary analysis that it is a sedimentary metamorphic ore deposit, hydrotherm re-- modelling stratabound lead and zinc deposit. The metallogenic materials mainly come from the stratum, controlling the spatial distribution of lead zinc ore in NE--NNE direction. The intersection of anticlinal axis and fault structure is a favorable for mineralization, while Lanhualing granitic pluton provides thermal power for the activated transfer and en- richment of leas zinc ore.
