摘要
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, the authors 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.
