摘    要:系统分析了晋、冀、蒙交界区2004—2007年间的流动重力测量资料,研究了重力场的时空动态演化特征。结果表明:地震孕育发生阶段,重力场出现一定范围的区域性重力异常,重力场变化与区域应力应变场变化及地震活动有关。目前,在晋、蒙交界的怀仁-山阴-朔州-带存在趋势性的重力负异常。

关 键 词:    蒙交界区  重力场  流动重力  时空动态演化特征

Abstract:In this paper,the mobile gravity data in the border area of Shanxi-Hebei-lnner Mongolia from 2004 to 2007 is systematically analyzed,and the dynamic evolutional characteristics of gravity field are obtained.The results show that the territorial gravity anomaly appears in a certain range during the stage of earthquake preparation,and the variations of gravity field are related with regional stress field and seismic activity.In Huairen-Shanyin-Shuozhou area,the long trend negative gravity anomaly appears at p...
Keywords:Border area of Shanxi-Hebei-lnner Mongolia  Gravity field  Mobile gravity  Time-space dynamic evolution characteristics
