中文摘要
本文将利用高精度三氧同位素数据,结合三硅数据和燧石微量元素数据,获取太古宙海水d18O的相关信息。我们想回答海洋的d18O是随时间变化还是保持不变的问题。这一信息对重建古深海温度具有重要意义。
英文摘要
In this proposal, we will use high-precision triple oxygen isotope data in combination with triple silicon data and trace elements of cherts to obtain information about the d18O of Archean seawater. We want to answer the question whether the d18O of the oceans changed during time or remained constant. This information has important implication the reconstruction of paleo-ocean temperatures deep in time.
