摘要
本文以宜昌—随州—大路庄剖面地区岩石的磁参数为基础，根据航磁异常特征及该区地质特征，设计了该区浅中部磁模型，据拟合计算结果建立了地质模型，并提出扬子准地台的结晶基底向北延伸，论述了扬子准地台、秦岭褶皱系、华北准地台三者的磁性特征及相互关系。
On the basis of magnetic parameters of rocks in the area cut across by the Yichang Suizhou-Daluzhuang profile,in accordance with aeromagnetic anomalies and geological char acteristics of this area, the magnetic model of shallow-middle depth of this area was de signed. The authors put forward the viewpoint that the crystalline basement of Yangtze para platform extends northward, and discussed the magnetic characteristics of Yangtze paraplat form, Qinling fold system and North China paraplatform and the relations between them.
