论文摘要
我们讨论了一项遥感研究的结果，该研究揭示了有关两个矿物主导的重要岩石单元的新细节，这些矿物可能与火山矿（橄榄石）和寿命（碳酸盐）相关。该研究使用了有关Crism数据的新分析技术，它鉴定了一个不存在碳酸盐或粘土的区域，只有大晶粒尺寸的橄榄石。这一发现揭示了耶泽罗火山口内橄榄石碳酸盐岩石岩石的形成和历史的新启示，这将由火星2020年漫游者探索。
We discuss the results of a remote sensing study that has revealed new details about an important rock unit dominated by two minerals that can be associated with volcanism (olivine) and life (carbonate). The study, which used a new analysis technique on CRISM data, identified a region where no carbonates or clays are present, only large grain size olivine. This discovery shines new light on the formation and history of the olivine-carbonate rock within Jezero crater that will be explored by the Mars 2020 rover.
