| 摘 要： | 银灿铜矿地处于北祁连走廊南山北坡—冷龙岭岛弧带中,矿区出露一套具双峰式火山岩特征的火山沉积建造,矿体主要赋存在石英角斑岩中并存在明显分带,上部为铜矿体向下部变为锌矿体,矿石类型属黄铁矿型多金属矿石,成矿作用过程直接或间接与火山活动有关,是北祁连地区早古生代典型的海相火山岩型块状硫化物矿床。

| Abstract: | The Yincan copper deposit located in an island arc belt which stretches from the north slope of South Mountains, Hexi corridor to Lenglong Mountain on North Qilian Orogen. A set of bimodal volcanic sedimentary formation distributed in the mining area. The ore-bodies occurred in the quartz keratophyre with obvious vertical mineralization zoning, the copper orebodies occurred at the top, and the zinc orebodies occurred at the bottom. The ore in this study was a pyrite-type polymetallic ore. The mineralization was directly or indirectly associated with volcanic activities, the deposit was a typical volcanic hosted massive sulfide type and formed in early Paleozoic on North Qilian Orogen. |
