| 摘 要： | 以江苏南部1∶50万航磁资料为基础,通过对区内岩矿石磁性特征的归纳与分析,对区内航磁异常形成的地质因素作了讨论,并对区内航磁异常进行了分类、分区及地质解释。通过进一步对区内航磁资料的数据处理,对区内深变质磁性基底面的埋深、形态特征及其地质意义作了讨论,对区内构造岩基带平面分布及垂向分布特征,特别是对长江断裂带也一并作了推断解释。

| Abstract: | Based on 1：50, 000 aeromagnetic anomaly data in southern Jiangsu, and through summary and analyses for rock magnetic characteristics in the study area, the author discussed the geological factors formed by aeromagnetic anomaly in the study area, conduc- ted classification, zoning and geological explanations for aeromagnetic anomaly in the study area. Through a further data processing for aeromagnetic data, the author discussed the burial, shape properties and geological significance for the deep metamorphic magnetic basement in the study area, made inferred interpretation for the tectonic bedrock plane distribution and vertical distribution, as well as Yangtze fracture zone especially. |
