PI将对赤道太平洋的几个中上层岩心进行采样,量化中上层沉积物的磁性减弱及其与古强度的关系,并进行定向记录。为了完成这项工作,他将收集大量的岩石磁(滞后测量,IRM, ARM, K,低温处理)和古磁数据(退磁剩余物),并将这些数据与磁分离(XRD, SEM, TEM)和地球化学分析(Fe, Mn, S)的信息结合起来。****
英文摘要
Tarduno 9418061 The PI will sample several pelagic cores from the equatorial Pacific to quantify magnetic reduction in pelagic sediments and its relationship to paleointensity and directional recording. To accomlish this he will collect a host of rock magnetic (hysteresis measurements, IRM, ARM, K, low temperature treatments) and paleomagnetic data (demagnetized remanence) and combine these with information from magnetic separates (XRD, SEM, TEM) and geochemical analyses (Fe, Mn, S). ****
