摘要:
新疆北部喀拉通克矿区,是中亚造山带的大型岩浆铜镍硫化物矿床,具有悠久的开采历史。该矿区地处准噶尔盆地与阿尔泰造山带的交汇部位,构造运动强烈。然而,矿区近年资源开采困难,深部找矿工作已成为矿区矿产勘查的重要目标。本文从矿区基本信息、动力学构造背景、地球物理特征、目前有待解决的科学问题等方面,多角度汇总喀拉通克矿区近年来地球物理探测研究进展。由于观测手段与分析方法的局限,目前矿区地下精细结构有待进一步提高观测分辨率。未来,联合多种地球物理探测方法、发展高分辨、多物理属性的结构成像方法,比如引入不同频段的地震方法等,加强岩石地球物理的基础实验研究,以获取壳幔精细结构和精确的矿体空间分布,将成为矿区研究工作的主要方向。

Abstract:
The Karatungk mine in northern Xinjiang, which is a large-scale magmatic Cu-Ni sulfide mine in the Central Asian orogenic belt, has a long history of mining. The mine locates at the merging belt between Altay orogenic belt and Junggar Basin, and it has strong tectonic activities. However, the ore bodies have been difficult to be exploited in recent years, and source detection study has become an important target for mineral exploration. In this paper, we systematically summarize the achievements of the geophysical exploration research in Karatungk mine from the following aspects, such as tectonic backgrounds of the mine, dynamic mechanisms, geophysical characteristics and scientific problems needed to be solved in the future. Due to the restrictions of observation density and analysis methods, the detailed shallow crustal structure of the mine cannot be clearly characterized yet. In the future, researchers may focus on combining multiple geophysical methods, developing high-resolution, multi-physical properties structural imaging methods, such as the introduction of seismic methods in different frequency bands, etc., and strengthening petrophysical experimental research to obtain the high-resolution structure and detailed spatial distribution of ore bodies.
