中国东北地区剩余重磁异常特征与地质构造及成矿带的关系

在分析中国大陆宏观格架、全国布格重力异常和东北地区1:50万剩余重、磁力异常的基础上，结合东北地质及构造演化史，分析了东北剩余重磁异常特征，并探讨了剩余重磁异常特征与地质构造的关系.总结了与成矿有关的剩余重磁场特征，说明了剩余重磁异常可在刻画地质构造、断裂分布、地层分布及成矿带方面提供重要的参考信息.

The relationships between the characteristics of Northeast China residual gravity and magnetic anomalies and geological tectonic & metallogenic belt

On the basis of analyzing the tectonic framework of China,bouguer gravity anomalies of China,residual gravity and magnetic anomalies with a scale of 1: 500,000 of Northeast China,with the geology and tectonic evolving history of Northeast China,the characteristics of Northeast China residual gravity and magnetic anomalies are analyzed.The relationships between the characteristics of residual gravity and magnetic anomalies and geological tectonic are discussed.The characteristics of residual gravity and magnetic anomalies related to metallogenic belt are analyzed and summarized.All of results show that residual gravity and magnetic anomalies provide a lot of important information in depicting geological tectonic,distribution of fracture and strata,metallogenic belt.
