| 摘 要： | 近年来,利用最大熵功率谱法计算磁性体深度受到了地球物理界的重视。本文利用该方法求取东北地学断面磁性层顶、底界面深度,并结合航磁ΔTa异常图及相应滤波图,判定了该断面几条主干断裂的位置与展布,其结果有的与地质推断基本一致,有的则有较大差异。

| Abstract: | To computer depth of magnetic body by means of power spectrum method of maxi-
mum entropy has attracted gcophysics circles's attention in recent years. Making use of the
method, the depth of upper and lower boundar of magnetically layer with respect to geo-
science pofile of Northeast China have been obtained.
Connecting the result with aeromagnetic anomaly map and corresponding filter map, sev-
eral main faults across the geoscience profile of Northeast China have been judged. |
