早期地球的环境条件及其可居住性最好地记录在表生沉积物中。在这个项目中,我们的目标是确定太古宙海洋的同位素组成和温度。我们采用了一种基于碳酸盐d17O和d18O高精度测量的新方法。
英文摘要
The environmental condition and thus habitability of the Early Earth is best documented by supergene sediments. In this project we aim to determine both, the isotopic composition and temperature of Archean oceans. We apply a new approach that is based on high precision measurement of d17O and d18O of carbonates.
