摘　　要：河北省境内 4 0多个已知成因类型侵入岩体的岩石物理性质与判别成因的地球化学指标统计分析 ,证明岩石物理性质能够反映侵入岩的成因类型 ;同时 ,发现岩石磁性反应的I型与S型侵入岩没有明显界线 ,所存在的过渡带是边缘成矿的良好地质环境 ;通过岩石密度、磁化率的空间分布数据 ,讨论了河北省侵入岩体成因类型的空间分布特征。Statistical analysis was carried out on the petrophysical parameters and geochemical indexes for more than 40 intrusive bodies located in Hebei Province. As a setting of marginal ore forming process, the transitional belt from I type to S type intrusive rocks does exist in nature. On he basis of the above mentioned reasons, the spatial distribution of I type and S type intrusive rocks has been mapped by density and susceptibility. The transitional belt from I type to S type intrusive rocks is considered to be a favorable area of mineral deposits.
