摘要
S型与I型花岗岩体在河北省境内广泛分布,前者含矿性不好,后者与成矿关系密切,普遍矿化。通过分析河北省高精度航磁资料,总结对比了S型与I型花岗岩体的航磁异常特征,并分析了它们磁性差异的原因,以便于在航磁资料的研究中圈定这两类花岗质岩体,区分矿与非矿异常,间接圈定找矿靶区。
The S-type and the I-type granite are distributed widely in Hebei province,which the first type hasnt ore potentiality , but the second type has better ore potentiality and widespread mineralization. The Hebei province high precision aieromagnetic data have been analyzed in this paper, We sums up and compares the anomaly character between the S - type and the I - type granite, and distinguish the anomaly between ores and barren rocks, aieromagnetic anomaly of the two types of granites are illustrated respectively and the causes of magnetic anomaly are also analysed, and last the targets are been indirectly delineated.
