| 摘 要： | 营口—宽甸地区重力场自北而南有逐渐增高的总趋势。中部区重力低与重力高呈带状相间出现。结合该区已知的地质构造特征综合分析,重力负值带是早元古宙拗拉槽边界深断裂和构造—岩浆岩带的反映。隐伏、半隐伏花岗岩体的解释和推断,为逃一步寻找金、硼、铅锌等矿产提供了信息。

| Abstract: | The gravitational field from Yingkou to Kuandian gradually increases in total from north to south,but in the central area,lower gravitational field alternating with higher field in belt.Considering the known synthetical studies on the characteristics of geological structures,the negative gravitational belt is considered to be a deep fracture or a tectonicmagmatic belts.The interpretation and deduction of concealed,half-concealed granite bodies provide information for looking for gold,boron,lead-zinc deposits. |
