| 摘 要： | 利用西沙群岛西琛一井３３０ｍ以上井段的１４９块岩心标本，用美国２－Ｇ型超导磁力仪进行了古地磁测定，获得了一个从更新世至中新世晚期包括布容，松山，高斯和吉尔伯特四个极性时及若干亚极性的磁性地层柱，为礁序列的划分对比，提供了新的依据。

| Abstract: | core samples from the interval between O and 300m depth in Well Xichen-l drilled at Xisha Islands are paleomagnetically measured on a superconductive magne-tometer 2-G made in U.S .A. ,and thus a magnetostratigraphic section from Pleistocene to Late Miocene including four chrons(Brunhes,Matsuyama, Gauss,Gilbert)and some subchrons is obtained,which has established a new basis for division and comparison of the reef sequence. |
