Relative Paleointensity in Sediments

[9315628 . Tauxe] PI将研究几种有前途的方法来标准化沉积物中的古磁强度记录。她将使用两个时间片（0和10 ka）来测试这些方法，这些时间片是在安通-爪哇高原的大片地区最近采集的箱形岩心中进行的；将选择两个盒芯进行连续采样，以便将两个时间序列与所有可用的归一化参数进行比较。然后，她将构建两个平行时间序列的相对古强度数据，这些数据来自安通-爪哇高原，跨度为过去的三到四百万年。最后，她将分析从意大利翁布里亚渐新世Contessa采石场采集的一组样本，以便建立第二个跨越Chron C12R的记录，与最近从DSDP Leg 73的Site 522从南大西洋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. ****
