摘要
新疆若羌县阿尔金山脉里维齐明铁矿地表是被一套前寒武系深变质岩覆盖的全隐伏矿床。该区以往研究程度很低,从未开展过地面矿产物探工作,本次研究的目的是利用地面高精度磁法测量,寻找深部隐伏的盲矿体。通过对其进行地面高精度磁法测量,获取了磁异常数据,圈定出了磁异常范围,通过化极处理和不同高度的延拓以及异常特征分析,确定了深部隐伏矿体的分布和空间特征。为铁矿床的开发提供了较为明确的地球物理依据。
Iron ore deposit of the altun mountain-liweiqiming is a hidden deposit,which was covered by a set of precambrian-cambrian boundary deep metamorphic rock.Through the surface high-accuracy magnetic survey,we obtained magnetic anomaly data and outlined the scope of the magnetic anomaly.Based on the analysis of reduction to the pole and upward continuation,the distribution and spatial signature of the hidden iron ore deposit were determined,which presented specific basis of physical geography for the development of iron ore deposit.
