Relative Paleointensity in Sediments

9315628国际地球物理研究所将研究沉积物中磁性古强度记录归一化的几种有希望的方法。她将使用最近在安通-爪哇高原大片区域采集的盒子岩芯中的两个时间片(0和10ka)来测试方法；将选择两个盒子岩芯进行连续采样，以便将两个时间序列与现有的全部归一化参数进行比较。然后，她将构建两个平行的时间序列，这些数据来自安通-爪哇高原，跨越过去300万到400万年。最后，她将分析从意大利翁布里亚的渐新世孔特萨采石场采集的一组样本，以构建跨越Chron C12R的第二个记录，并与最近从南大西洋73号腿的S遗址522获得的记录进行比较。****

9315628 Tauxe The PI will investigate several promising approaches to normalization of magnetic paleointensity records in sediments. She will test the methods using two time slices (0 and 10 ka) in recent box cores taken over a large area of the Ontong-Java Plateau; two box cores will be selected for continuous sampling in order to compare the two time series with the full range of normalization parameters available. She will then construct two parallel time series of relative paleointensity data from the Ontong-Java Plateau spanning the last three to four million years. Finally she will analyze a set of samples collected from the Oligocene Contessa Quarry section in Umbria, Italy, in order to construct a second record spanning Chron C12R to compare with one recently obtained from DSDP Leg 73's Site 522 from the South Atlantic. ****
