为了确定重力方法能否用来模拟结构与密度都变化的基底及上伏沉积岩,我们在艾伯塔省南部克莱索勒姆(Claresholm)东部地区对重力和地震资料进行了综合解释。沿着三条试验剖面观测到的布格重力异常幅值达到50个重力单位,并用前寒武纪基岩的块断作用以及上伏盖层的密度结构来解释所观察到的异常。重力异常是由许多断块的垂向运动(其断距长达300米)以及白垩纪沉 In order to determine whether the gravity method can be used to model both the structural and density-changing basement and the underlying sedimentary rocks, we provide a comprehensive explanation of gravity and seismic data in eastern Claresolm, Alberta. The observed Bouguer gravity anomaly amplitude along the three experimental sections reached 50 gravimetric units and interpreted the observed anomalies using the block-breaking of the Precambrian rocks and the density structure of the overlying caprock. Gravitational anomalies are caused by the vertical motion of many fault blocks (up to 300 meters apart) and the crevice
