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

9304797克莱门特最近的解释古地磁记录的极性转变引起了很大的争议过渡VGP往往下降沿着两个首选的纵向带。虽然一些工作者解释的过渡VGP的地理分组的证据表明，大规模的对称性存在于过渡领域，其他人认为，分组，如果显着，结果从沉积物中的记录过程的人工制品。显然，需要更多的记录来解决这一争议，因此，PI开展了一个项目，对斐济苏瓦泥灰岩中记录的六个上新世极性转换进行了采样。原有赠款的更新将支持对苏瓦泥灰岩中四个已确定的过渡区进行精细、详细的取样。***

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. ***
