中国海陆磁力异常图磁场分区及断裂划分

Subdivision and fault identification of the magnetic anomaly map of China mainland,offshore and adjacent areas

中国海陆1500万磁力异常图编制主要根据50多年来国内实测的航空物探资料,并且包括了截至2012年底前最新的陆域测量和近年来实施的一系列海域专项调查资料和研究成果,资料精度较高.为了充分利用区域磁场图的价值,对中国海陆1500万磁力异常图进行了断裂划分及磁场分区.

The magnetic anomaly map（15,000,000）of China mainland,offshore and adjacent areas covers China and neighboring countries.For map compilation of China mainland and offshore areas,the aeromagnetic data measured in last 50 years or more have been collected and arranged.They also include the new land measurements by the end of 2012 as well as special investigations and studies of offshore regions in recent years,which have relatively high accuracy.The 15,000,000 magnetic anomaly map displays clearly tectonic features of China mainland,offshore and adjacent areas,and provides geophysical evidence for identifying faults and Subdivision in these regions.
