| 摘 要： | 天水市水洞沟金矿床位于祁连—北秦岭加里东造山带接合部位的巨大反S型构造带南侧,金矿化严格受EW向断裂控制。围岩蚀变以硅化、褐铁矿化、黄铁矿化、绢云母化为特征。主要载金矿物是褐铁矿、黄铁矿、毒砂。变砂岩、韧脆性断裂构造、中酸性侵入岩是控制矿床形成的基本条件,近EW向构造蚀变带及化探异常发育部位是找矿有利地段。

| Abstract: | Shuidonggou gold deposit in Tianshui city is located in the southern side of the great reversed "S" type structure in the junction area of Caledonian orogenic belt of Qilian and north Qinling,where gold mineral-ization is controlled strictly by EW-striking fractures.The walk-rock alteration is characterized by silicification,limonitization,pyritization and sericitization.The gold-bearing minerals mainly are limonite,pyrite and arsenopy-rite.The results of study show that the basic conditions of deposit form... |
