High Resolution Records of Early Pliocene Geomagnetic Polarity Transitions from the Southern Hemisphere (Fiji)

9304797克莱门特最近对极性转变的古地磁记录的解释引起了关于过渡VGP的巨大争议，这些VGP往往沿着两个首选的纵向带落下。虽然一些工作人员将过渡性VGP的地理分组解释为过渡区中存在大尺度对称性的证据，但另一些人则认为，这种分组--如果意义重大--是沉积物记录过程的人工产物。显然，需要更多的记录来解决这一争议，为此，国际和平研究所开展了一个项目，对斐济Suva Marl记录的六个上新世极性转变进行采样。原赠款的续期将支持对苏瓦马尔四个已确定的过渡区进行精细、详细的抽样。***

9304797 Clement Recent interpretations of paleomagnetic records of polarity transitions have given rise to a great deal of controversy over transitional VGPs which tend to fall along two preferred longitudinal bands. While some workers have interpreted the geographical grouping of transitional VGPs as evidence that large scale symmetries were present in the transitional fields, others have suggested that the grouping, if significant,results from an artefact of the recording process in sediments. It is clear that additional records are required to resolve this controversy, and for this reason the PI undertook a project sampling six Pliocene polarity transitions recorded in the Suva Marl in Fiji. Renewal of the original grant will support fine-scale, detailed sampling of four identified transitions zones in the Suva Marl. ***
