CORRELATIVITY OF THE CIRCULAR STRUCTURE IMAGES WITH THE GRAVITY AND MAGNETIC ANOMALIES AND ITS IMPLICATION FOR THE FUTURE COAL INVESTIGATION

The concealed magmatic rock bodies at the southeast of the Xuefeng Upheaval in Hunan are circular in the landsat images. These circular images are identical wonderfully with those in the gravity and magnetic anomalies figure in shape, size and location. The concealed or subconcealed coal basins are also of circular shapes in the landsat images, but show the negative anomalies in the gravity figure. So it is of practical value to make use of the landsat images and the materials of the gravity and magnetic anomalies for explaining and distinguishing the magmatic rock bodies and the coal basins.
