| 摘 要： | 乌兰乌珠尔铜矿床处于柴达木陆块西南缘、祁漫塔格山北坡-夏日哈新元古代-早古生代岩浆弧带西段,属祁漫塔格-都兰华力西期铁、钴、铜、铅、锌、锡、硅灰石（锑、铋）成矿带,是青海省内矽卡岩型铁多金属矿的主要成矿带,成矿地质条件优越。乌兰乌珠尔铜矿床的发现为该地区寻找类似的斑岩型铜矿床提供了一个实例。本文通过对乌兰乌珠尔铜矿区地质特征、地球物理及地球化学异常特征、硫氧同位素特征、蚀变类型、分带特征及其与矿化之间的关系等方面的分析研究认为矿床形成与破碎蚀变带中的斑岩脉有关,矿体围岩具有典型的斑岩型矿床蚀变分带特征,蚀变主要有钾化、绢英岩化和青磐岩化3种类型,铜矿化主要分布于绢英岩化蚀变岩中,而铜矿体则全部集中在强绢英岩化岩石中,总结了铜矿床的地质特征,并对其成因类型和找矿前景进行了分析。

| Abstract: | Wulanwuzhuer copper deposit is skarn iron polymetallic deposit in Qinghai province and the ore-forming geologic condition is excellent.Based on the analysis and study on the geological characteristics,geochemical and geophysical anomaly characteristics,sulfur oxygen isotopic characteristics,alteration types,zoning features and their relationship with the mineralization,etc.in Wulanwuzhuer copper ore field,it shows that deposit formation relates to the porphyry veins in the broken alteration zone,and the copper mineralization mainly distribute in the phyllic alteration rocks,while all of the copper body concentrate in the strong phyllic alteration rocks. |
