The field gravity and magnetic data of the ore concentration area in the middle and lower reaches of the Yangtze River.rar

Geophysical surveys were conducted around the study area, mainly consisting of 1:20,0000 gravity and 1:5,0000 high-precision aeromagnetic surveys. The field gravity and magnetic data are comprehensive reflections of the subsurface and the surrounding geological bodies. To obtain the gravity and magnetic responses of subsurface geological bodies, the measured gravity and aeromagnetic data need to be corrected, the gravity data need to be corrected for mixed zero drift, latitude, intermediate layer, and topography, and the aeromagnetic data need to be corrected for integrated effects, normal field, daily variation, and compensation and equalization to obtain the Bouguer gravity anomaly and magnetic anomaly
