METALLOGENIC PROSPECT PREDICTION BY GRAVITY SURVEY IN DUNHUA-SHANGZHI AREA, JILIN PROVINCE

Based on the result of 1:200 000 regional gravity survey, the characteristics of gravity field in DunhuaShangzhi area, Jilin Province are interpreted to infer the structural controlling regularities to rocks and ores. With study on the relationship between the distribution of deposits and the gravity field, some metallogenic prospect areas are predicted, involving 9 endogenetic metal prospect areas, 4 coal-bearing areas and 3 iron-polymetal areas. High-precision geomagnetic and transient electromagnetic methods areas are suggested to probe the shapes and spatial distribution laws of the orebodies in the prospect areas.
