STRUCTURAL ORE-CONTROLLING CHARACTERISTICS AND FAVORABILITY ANALYSIS OF THE KALAMAILI GOLD ORE BELT IN EAST JUNGGAR

Geological Survey Institute of Xinjiang, Urumqi 830000, Xinjiang, China

摘要

摘要: 东准噶尔卡拉麦里金矿带是新疆重要的成矿带之一，已经发现的金矿床（点）有100多处。区内断裂构造极为发育，主要的断裂构造有卡拉麦里深大断裂、清水—苏吉泉断裂和库普大断裂，由大断裂派生的次级断裂广泛发育，与金的成矿关系极为密切。在已有研究的基础上，借助遥感解译技术，在数理统计的基础上，总结了卡拉麦里金矿带构造控矿特征，并初步进行了有利度分析。结果表明：北西—北西西向的断裂为该成矿带内极为有利的控矿构造，其控制了成矿带的展布，与其共生的次级断裂和派生断裂为容矿构造，控制着矿床（点）的位置。北东—北东东和北东对金矿的控矿作用不明显。金矿床（点）多分布在5~15个/100 km²的密度区内。线性构造交汇点密度高峰值为25个/100 km²，随着密度值的增高，金矿床（点）逐趋减少。

Abstract: The Kalamaili gold ore belt in East Junggar is one of the important metallogenic belts in Xinjiang, and more than 100 gold deposits (points) have been discovered. The fault structure in the area is extremely developed. The main fault structures include the Kalamaili deep fault, the Qingshui-Sujiquan fault and the Kupu large fault. The secondary faults derived from the large fault are widely developed and closely related to gold mineralization. Based on previous studies and mathematical statistics, using the remote sensing interpretation technology, the structural ore-control characteristics of the Kalamaili gold ore belt are summarizes and a preliminary advantage analysis is conducted. The results show that the NW-NWW fault is an extremely favorable ore-controlling structure in the metallogenic belt, which controls the distribution of the metallogenic belt, and the secondary faults and derived faults associated with it are the ore-bearing structures, controlling the deposit (Point) location. The ore-controlling effect of NE-NEE and NE on gold mines is not obvious. Gold deposits (points) are mostly distributed in the density zone of 5~15/100 km². The peak density of the linear structure intersection point is 25/100 km². As the density value increases, the gold deposits (points) decrease.
