喀腊大湾铜矿床地质特征及找矿标志

Geological Characteristics And Prospecting Criteria Of Dawan Copper Deposit, Kara

喀腊大湾铜矿位于新疆若羌县阿尔金东段喀腊大湾上游,阿尔金北缘断裂以及阿尔金断裂相互交接的区域上是该矿的大地构造位置所在,该带助于红柳沟-拉配泉奥陶纪裂谷带,区内历经非常复杂的构造演化特征,环境非常多变。卓阿布拉克组中浅变质岩系(中元古界蓟县系)在区内广泛出露,该区岩浆互动非常突出,不仅有火山岩分布,而且发育大量的侵入岩以及中基性岩脉和次火山岩等。文中对喀腊大湾铜矿床地质特征进行分析,并总结其找矿标志。旨在为区内同类型矿床的寻找提供参考。

The Kaladawan copper deposit is located in the upper reaches of the Kaladawan in the eastern section of Altun, Ruoqiang County, Xinjiang. The tectonic location of the deposit lies in the area where the northern Altun margin fault and the Altun fault meet each other. This zone contributes to the Ordovician rift zone of Hongliugou-Lapeiquan, which has undergone very complex tectonic evolution characteristics and a very variable environment. The middle-low metamorphic rock series (Jixian series of the Middle Proterozoic) of the Zhuoabulak Formation is widely exposed in the area. Magmatic interaction is very prominent in this area. Not only are there volcanic rocks, but also a large number of intrusive rocks, medium-basic dikes and subvolcanic rocks are developed. In this paper, the geological characteristics of the Dawan copper deposit in Kara are analyzed and its prospecting criteria are summarized. The purpose is to provide a reference for the exploration of the same type of deposits in this area.
