GEOPHYSICAL CHARACTERISTICS AND GEOLOGICAL EXPLANATION OF THE MIDDLE SECTION OF DAXINGANLING REGION

Based on the regional geology and geophysical data, a comprehensive explanation is made about the characteristics of gravity and magnetic anomaly of the middle section of Daxinganling region. The relationship between the regional distribution of mineral resources and gravity-magnetic field is discussed. The characteristics of magnetic anomalies vary for different kinds of mineral resources. Thus the gravity-magnetic anomaly can guide poly-metallic ore searching in the region.
