福建省深部构造研究工作做得很少,前几年曾从重力场特点用延拓十、十五、二十、二十五公里把闽赣两省区域重力异常从布格重力异常分离出来。1979年省航空物探大队又完成了全省航磁测量工作,并编制了1:50万福建省航磁△T平面图,此后又把区域磁场从磁异常分离出来。它们反映了地壳深部物质密度与磁性分布状况,而这种状况往往与深部构造轮廓 In the past few years, the gravity anomalies in the Fujian-Jiangxi provinces have been separated from the Bouguer gravity anomalies by the extension of ten, fifteen, twenty and twenty-five kilometers in Fujian and Jiangxi provinces. In 1979, Provincial Aviation Geophysical Brigade completed aeronautical surveying work in the province and prepared 1: 500000 aviation aeromagnetic △ T plane map, and then separated the regional magnetic field from magnetic anomaly. They reflect the deep crustal material density and magnetic distribution, and this situation is often associated with deep tectonic outline
