摘　　要：根据1∶20万区域重力调查工作成果,以重力场特征解释推断构造控岩、控矿基本规律.通过研究矿床(点)分布与重力场关系,划分内生金属矿产成矿远景预测区9处,含煤远景预测区3处,例举铁及多金属3处,含煤远景1处.建议在这些远景区开展高精度地磁及可供源法和瞬变电磁法工作,探讨深层矿体形态及空间展布规律.Based on the result of 1 ： 200 000 regional gravity survey, the characteristics of gravity field in Dunhua- Shangzhi 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.
