【摘要】 根据安徽省重力异常和航磁异常平面特征,对两淮煤田的地球物理场特征进行了分析与探讨,分析了航磁和重力异常的平面特征和分区特征。研究结果表明,重磁异常的区域平面特征与平面地质构造特征相对应,区域性的航磁异常不仅反映了太古界磁性基底的现势展布,同时也反映了磁性基底断块的旋扭和平移特征,重力异常特征反映了中生带凹陷或断陷盆地内的松散沉积特征及基底的分布特征,与地层内密度变化关系密切相关。更多还原

【Abstract】 According to the gravity anomaly and aeromagnetic anomaly plane characteristics in Anhui Province, the geophysical field characteristics of the Lianghuai coalfield were analyzed and discussed. The plane characteristics and regional characteristics of aeromagnetic and gravity anomalies were analyzed. The results showed that the regional planar features corresponded to the planar geological structural features. The regional aeromagnetic anomalies not only reflected the current distribution of the magnetic basement of the boundary, but also reflect the twisting and translation characteristics of the magnetic basement fault block. The gravity anomaly characteristics reflected the loose sedimentary characteristics and the distribution characteristics of the basement in the Mesozoic zone depression or fault basin, which was closely related to the density variation in the stratum.更多还原
