通过西太平洋暖池温区中心WP 92-5柱样沉积物磁性地层学、磁化率和δ18O等测试与分析,获得了布容正极性期内哥德堡、莫诺湖(Mono Lake)和蒙哥(或Maelifell)3个短暂的地球磁场漂移,它们发生的时间约12.1～11.3,25.0～24.0和31.0～28.0 kaBP;并从该柱样的磁化率记录中发现Younger Drvas(YD)和Heinrich冷事件沉积层.YD冷事件出现于30～22 cm,年龄约11.5～10.6 kaBP;Heinrich层中的H1,H2和H3冷事件分别出现于51～39,108～91和140～126 cm,发生时间约15.1～13.0.25.0～22.1和30.6～28.2 kaBP,与大西洋中部SU90-09柱样沉积物磁化率所记录的H1,H2和H3冷事件具有较好的对应关系,表明磁化率的变化可能是气候频繁颤动特征在大洋沉积中的一个重要标志.
Through the test and analysis of the magnetic stratigraphy, magnetic susceptibility and δ18O of WP 92-5 column-like sediment in the West Pacific Warm Pool Center, the thermal characteristics of Gothenburg, Mono Lake and Montgomery Or Maelifell) for three short earth magnetic field drifts that occurred from 12.1 to 11.3, 25.0 to 24.0 and 31.0 to 28.0 kaBP, respectively; and the Younger Drvas (YD) and Heinrich cold event deposits were found from the susceptibility log of the column The cold event of YD occurs at 30-22 cm and the age is about 11.5-10.6 kaBP. The cold events of H1, H2 and H3 in Heinrich layer occur at 51-39, 108-91 and 140-126 cm, respectively, and the occurrence time is about 15.1-13.0 .25.0 ~ 22.1 and 30.6 ~ 28.2 kaBP, respectively, which are in good agreement with the H1, H2 and H3 cold events recorded by the susceptibility of the SU90-09 column sediments in the mid-Atlantic region, indicating that the change of magnetic susceptibility may be characterized by frequent climate chatter An important symbol in the sedimentation of the oceans.
