Abstract
LuanpingⅡ iron deposit was a hidden deposit and was covered by Mesozoic strata.The magnetic anomalies were outlined and the magnetic data were obtained by magnetic survey.Magnetic anomalies consist by a series of over 800 nT positive anomalies were arranged in northeastern and partly in zigzag,the anomaly centers were located in the zigzag part.Based on the analysis of reduction-to-pole and upward continuation,4 high anomaly areas were located,and the relatively depth of the high anomaly areas was analyzed.This provided geophysical foundations for mineral prospecting.
