Application of High-Precision Magnetic Survey to Prospecting: A Case Study in the Galinge Deposit of Qinghai Province
摘要
Abstract
Although magnetic survey is a direct and efficient method for ore search, its effect is limited in the Galinge iron deposit of Qinghai Province. The reason is that thick cover and big depth of buried ore bodies characterize this deposit, thus the magnetic anomalies are of simple form that makes detection of deep concealed ore bodies difficult. Based on previous work, we used the wavelet multiple-scale method to analyze magnetic anomalies on the plane of this area. We discovered that five-order wavelet details are ore anomalies, and inferred that there may be magnetite bodies 500 meters below the surface. Meanwhile human-computer interactive inversion confirmed the existence of concealed ore bodies. This case shows that wavelet analysis and human-computer interactive inversion methods provide a new approach to enlarge prospective reserves of the Galinge iron deposit.关键词
