Lateral variation of aeromagnetic anomaly in South China and its tectonic implications

We present a series of images from the aeromagnetic data observed in South China areas, and reveal the detailed structures of the South China Block. By using lateral variation of the aeromagnetic anomalies, we characterize individual geological blocks and suggest the deep boundaries of the blocks. The Yangtze Block and Jiangnan orogenic belt are characterized by low aeromagnetic anomalies, whereas high values of the aeromagnetic anomaly are...
