新疆昆仑山阿尔金一带金矿床地质特征及成因分析
|
摘要
阿尔金山位于塔里木盆地的东南缘,是青藏高原北缘的一部分,阿尔金成矿带是我国重要的成矿带之一,有着非常重要的研究价值。但相对而言该区的地质研究工作相对薄弱。随着近年来矿产资源需求量的不断极大,该区的地质找矿工作成为研究热点地区,金属矿产勘查评价取得了巨大的突破,相继发现了诸多金矿床(点),如与火山作用有关的浅成低温热液金矿床(采石沟金矿),与钾长花岗岩侵入有关的热液金矿床(大平沟金矿)和卡林型金矿床(祥云金矿)等,显示该区巨大的找矿潜力。下文结合实践,对新疆昆仑山阿尔金一带金矿床地质特征展开分析,并对起矿床成因进行探讨,希望能为相关工作的开展提供有益参考。
Altun Mountain is located in the southeastern margin of the Tarim Basin and is a part of the northern margin of the Qinghai-Tibet Plateau. The Altun metallogenic belt is one of the most important metallogenic belts in China and has very important research value. But the geological research in this area is relatively weak. With the increasing demand for mineral resources in recent years, the geological prospecting work in this area has become a hot research area. Great breakthroughs have been made in the exploration and evaluation of metallic minerals. Many gold deposits(spots) have been discovered successively, such as epithermal gold deposits(Quanshigou gold deposit) related to volcanism and hydrothermal gold deposits(Dapinggou gold deposit) related to the intrusion of potassium feldspar granite. The Carlin type gold deposit(Xiangyun gold deposit) and so on show the huge prospecting potential in this area. In this paper, the geological characteristics of the gold deposits in the Altun area of Kunlun Mountains in Xinjiang are analyzed, and the genesis of the deposits is discussed, hoping to provide useful reference for the related work.
