The S-type and the I-type granite are distributed widely in Hebei Province, which the first type hasn’t ore potentiality, but the second type has better ore potentiality and widespread mineralization. The Hebei Province high precision aeromagnetic data have been analyzed in this paper, the authors sum up and compare the anomaly character between the S-type and the I-type granite, and distinguish the anomaly between ores and barren rocks. Aeromagnetic anomaly of the two types of granites are illustrated respectively，the causes of magnetic anomaly are also analyzed and the targets are been indirectly delineated.
