The Perseverance rover landed in Jezero crater, Mars in February 2021. We used the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument to perform deep ultraviolet Raman and fluorescence spectroscopy of three rocks within the crater. We identify evidence for two distinct ancient aqueous environments at different times. Reactions with liquid water formed carbonates in an olivine-rich igneous rock. A sulfate-perchlorate mixture is present in the rocks, probably formed by later modifications of the rocks by brine. Fluorescence signatures consistent with aromatic organic compounds occur throughout these rocks, preserved in minerals related to both aqueous environments.

火星 Jezero 陨石坑的水蚀变过程 - 对有机地球化学的影响

毅力号火星车于 2021 年 2 月降落在火星的 Jezero 陨石坑。我们使用有机物和化学物质的拉曼和发光扫描可居住环境 (SHERLOC) 仪器对陨石坑内的三块岩石进行了深紫外拉曼和荧光光谱分析。我们确定了不同时期两种截然不同的古代水环境的证据。与液态水的反应在富含橄榄石的火成岩中形成碳酸盐。岩石中存在硫酸盐-高氯酸盐混合物，可能是由于后来盐水对岩石进行了改造而形成的。与芳香族有机化合物一致的荧光特征出现在这些岩石中，保存在与两种水环境相关的矿物中。
