摘要:	摘要： A striking high magnetic anomaly belt (HMAB) trending almost SW-NE is situated along the continental shelf edge off the southeastern Chinese continent. It extends northeastward to central Taiwan and gradually vanishes there. In this paper, magnetic simulation is performed and compared with other geological and geophysical data to establish a better under-standing of the nature of the magnetic source of HMAB and how it makes HMAB vanish. The magnetic simulation was performed with a geometrical constraint from the seismic velocity structure published in literature. Our simulation shows that there is a layer of material with high magnetic suscepti-bility (which should be the source of HMAB), situated near the center of the thick crust, along the trend of HMAB. This source layer should be the magmatic relic intruded along the continental shelf edge off the Chinese continent during the initial stage of the opening of the South China Sea. The change in physical conditions or large-scale dislocation of the source material due to intensive and complicated crustal deformation are concluded to be the possible causes of the gradual van-ishing of HMAB near its northeastern end. 出版者：台灣: 國立臺灣海洋大學出版日期： 2016-04-01 出處： Journal of Marine Science and Technology, 2016-04, Vol.24 (2), p.359-369 資源來源： Chinese Electronic Periodical Services (CEPS) 識別號： ISSN: 1023-2796 識別號： DOI: 10.6119/JMST-015-0702-1
