| 摘 要： | 通过对冀北地区变质岩系中角闪岩、片麻岩以及遵化群、整个变质岩系磁化率的统计分析与空间分析,提出低磁化率可能是副变质岩、高磁化率是正变质岩的反映,并由此探讨利用岩石磁学指标恢复变质原岩的可能性. |

| Abstract: | Statistics analysis and spatial analysis of 4 rock susceptibility data sets including amphibolite, gneiss, Zhunhua Gr., all metamorphic rock have been carried out in the paper and have gotten some conclusion as following: every unit can divided into two groups, one group with lower susceptibility may be parametamorphite and other group with higher susceptibility may be orthometamorphite. Therefore, the paper suggests the susceptibility of metamorphic rock may be add to recover the matamorphite protolith. |
| Keywords: | Northern Hebei province Metamorphite Susceptibility Protolith |
