From: 3D inversion of the Sichuan Basin magnetic anomaly in South China and its geological significance
Magnetic anomaly in Sichuan Basin. a Total-field aeromagnetic anomaly at 4Â km altitude. b RTP (reduction-to-the-pole) aeromagnetic anomaly at 4Â km altitude. c Total-field long-wavelength magnetic anomaly. The data are from the MF7 model using CHAMP satellite measurements and compiled at WGS-84 ellipsoid altitude. It could be downloaded from the website http://geomag.colorado.edu/magnetic-field-model-mf7.html. d RTP long-wavelength magnetic anomaly. The main thrust faults have been overlaid to each magnetic anomaly
