【摘要】 对福建省长乐县首祉的ch3钻孔的岩芯样品作了古地磁测量。测定了35000年以来磁倾角随时间的变化。在布容正向期中发现了一个极性反向事件。经C14年龄测定,该事件(长乐事件)的年龄为距今19000年到16000年。与其它地区的极性事件和视古地磁极游移相比,初步确定这个长乐事件相当于拉尚事件。
【Abstract】 The paleomagnetic measurements of the samples of the core from Shouzhi,Changle county,Fujian province have been made.The magnetic inclination changes with time during the last thirty five thousand years have been determined.A magnetic event was discovered during Brunhes epoch.C14 dating showed that it lasted from 19000 BP to 16000 BP.Comparison with events and excursions in other regions suggests its comtemporary with Laschamp event.
