新疆奇台县乌伦布拉克铜矿床控矿地质条件及成因探讨

Exploration on the geological conditions and genesis of the Ulunbulak copper deposit in Qitai County,Xinjiang

乌伦布拉克铜矿床位于准噶尔东北缘,属新疆奇台县管辖,是目前北塔山地区古生代复合岛弧带内最具规模的铜矿床之一,该矿床的发现填补了北塔山一带(塔尔巴哈台-阿尔曼太Au-Cu-Fe-铬铁矿矿带)无斑岩型铜矿的空白,对该地区寻找同类型矿床具有一定指导意义。矿床成矿地质条件复杂,成因类型至今一直存在较大争议。

The Ulunbulak copper deposit is located on the northeast edge of Junggar and is under the jurisdiction of Qitai County,Xinjiang.It is currently one of the largest copper deposits in the Paleozoic composite island arc belt in the North Tashan area.The discovery of this deposit fills the gap in the absence of porphyry type copper deposits in the Tarbahatai Almantai Au Cu Fe chromite ore belt in the North Tashan area,and has certain guiding significance for searching for similar deposits in the region.The geological conditions for ore deposit mineralization are complex,and there is still significant controversy over the consistent genetic types.
