摘要
1:5万地质调查中的综合物探工作包括综合剖面测量、岩石(地层)磁性测试,以及重、磁场资料的处理等。应用重、磁场特征,划分重、磁场的地质分区,确定地质体,地质构造的划分标志,印证地质填图中的结果和推断深部地质体和地质构造,完成深部地质图。1:5万地质填图中综合物探工作的开展,提高了地质图的精度,为深部地质研究提供了依据。
Synthetic geophysical operations in 1: 50000 geological surveying include surveying synthetic sections and rock (stratum) magnetism, and processing data of gravitational and magnetic fields. Based on the characteristics of gravitational and magnetic fields,geological provinces may be divided,division marks of geological bodies and structures can be defined, deep geological sketch can be completed through confirming the results of charting and deducing deep geological bodies and structures. The geophisical operations make the geological working more precise and provide more basis for deep geological studies.
