【摘要】 本文利用东大别构造带地震地磁监测试验区的地磁三分量观测数据,建立了试验区的岩石圈磁场模型,并将其与2005.0年代该区域的岩石圈磁场进行对比分析,研究试验区岩石圈磁场的时空变化特征.结果显示试验区内岩石圈磁场的分布从河南商城、安徽金寨、霍山至六安之间围绕梅山—龙河口、青山—晓天等断裂存在异常变化.更多还原

【Abstract】 Based on three-component geomagnetic data of the seismomagnetic test area in the eastern Dabie orogen, the geomagnetic lithosphere model is established.By making a comparison of the geomagnetic lithosphere model with 2005.0 geomagnetic lithosphere model,the time-space variation features of the geomagnetic lithosphere in the test area are studied.The results show that anomalous changes of the geomagnetic field of lithosphere are present around the Meishan-Longhekou fault and QingShan-XiaoTian fault.更多还原
