Abstract：we conclude and sum up on the character of the Gravity and magnetic field in the project on the Hebei province iron ore resource potential evaluation and metallogenic prediction in this paper.The larger positive aeromagnetic anomalies are mainly reflected by the emergence or hidden intrusive batholith; A larger area of distribution of lower and positive magnetic anomalies are mainly reflected by the acidic volcanic rocks in the Archean metamorphic rocks or the edge of the basement uplift zone where the sedimentary-metamorphic iron ores distribute densely; The negative magnetic field is always reflected in the Upper Proterozoic, Paleozoic carbonates and Mesozoic acidic volcanic-sedimentary rocks;The higher, larger gradient, or the local magnetic anomalies associated with the negative may be a reflection of the magnetic iron ore.The magnetic iron ore are mainly distributed in the gravity gradient zone or abnormal distortions and the border between the positive and negative anomalies From the features of gravity, field,where they are closely related to the strongly-deformed geological structure. We can make a realistic geological interpretation only by deep geological analysis on the gravity and magnetic field and comparison analysis combined with the identification marks built in the typical deposit.
