High Precision U-Series Dating of Carbonates and Marine Geochemistry of Rare Earth Elements, Actinide and Platinum Group Elements

PI将继续他在碳酸盐的高精度定年和稀土元素的海洋地球化学方面的工作，并考虑到多个目标，包括：确定过去400k年的海洋碳酸盐的年代学；海洋阶地及其与海平面变化的关系孔隙水同位素化学及成岩作用对U-Th时计的影响海水中铂和银的丰度；Nd， U和Th的地球化学。这项工作将有助于完善碳-14的时间尺度和最近过去海平面变化的年表。

The PI will continue his work on high precision dating of carbonates and marine geochemistry of rare earth elements with multiple objectives in mind, including: the determination of chronology of marine carbonates of the past 400 K years; marine terraces and their relationship to sea-level changes; isotopic chemistry of pore waters and the effect of diagenesis on U-Th chronometer; abundance of Platinum and Silver in seawater; and geochemistry of Nd, U and Th. The work will help refine the C-14 time scale and the chronology of sea-level changes of the recent past.
