| 摘 要： | 甘肃西和县李家山多金属矿床位于秦岭造山带西段，处于西成铅锌矿田西延部位，赋矿地层为中泥盆统西汉水群，成矿条件类似。研究表明本区矿床矿化主要为两种类型，一种是产于千枚岩或灰岩中的含铜石英脉型矿体，另一种是产于灰岩与千枚岩接触部位的硅化灰岩型铅锌矿体。它们既受构造控制，又受特定岩性控制，属沉积一改造型“层控”矿床。

| Abstract: | Lijiashan polymetallic deposit,Xihe county,Gansu Province,is located in the west section of the Qinling orogenic zone,the west-extending part of Xicheng lead-zinc mine.It has similar mineralization condition with Xicheng lead-zinc mine.The Middle Devonian Xihanshui group is the ore-bearing strata.Our results indicate two mineralization types of our study area : one is the quartz vein ore body containing copper,produced in the phyllite or the calcareous rock,the other is silicification calcareous rock lead-z... |
