摘要：
以卫星重力数据和航磁异常数据为基础，结合已知矿床位置，分析了区域矿床处重磁异常的特点。利用相关性研究方法，总结出成矿位置重磁异常与地形高程的相关性关系，并统计重磁异常轴的方向。通过分析重磁分布特征，发现矿床呈条状、面状分布，并预测大兴安岭断裂带，额尔古纳成矿带边缘以及哈尔滨北部为矿产资源潜力区。 |

Abstract:
Based on satellite gravity data and aeromagnetic anomaly data，the distribution characteristics of gravity and magnetic anomaly of the deposits were analyzed together with the specific location of deposits． By means of mathematical statistics，we obtained the correlation between the anomalies of gravity and magnetic and the topographic elevation in the deposit location． The direction of the regional gravity and magnetic anomaly axis was also obtained by statistics． By analyzing the characteristics of gravity and magnetic distribution，we find that the deposits are distributed in strip-like and planar-like shape． The Da Hinggan Mountains fault zone，the edge of the Ergun mineralization belt，and the north of Harbin are delineated as potential area of metal resources． |
