ExoMars Raman Laser Spectrometer RLS, a tool for the potential recognition of wet target craters on Mars
摘要：
在目前的工作中，近红外光谱，激光诱导紫外光谱，拉曼光谱和XRD技术已互补使用，进行全面的表征，从切萨皮克湾的影响结构（CBIS）选择的陆地模拟。所获得的数据清楚地突出了拉曼光谱在检测微量和痕量化合物中的关键作用，通过该作用可以推断出CBIS中发生的地质过程。除了使用商业系统外，还通过拉曼激光光谱仪（RLS）ExoMars模拟器进行了进一步的拉曼分析。该仪器是有效预测将于2021年在火星上部署的ExoMars/Raman系统科学能力的最可靠工具。通过模拟ExoMars任务漫游车设计确定的分析程序和操作限制，证明RLS ExoMars模拟器能够探测石英的非晶化，这构成了陨石坑撞击起源的分析线索。另一方面，对重晶石和菱铁矿这两种在热液条件下结晶的化合物的检测有助于间接确认撞击目标中是否存在水。此外，还评估了RLS ExoMars模拟器执行智能分子映射的能力。根据所获得的结果，为它的操作开发的算法提供了一个很大的分析优势，超过了大多数商业拉曼仪器所采用的自动分析系统，鼓励其应用于许多额外的科学和商业目的。
英文摘要：
In the present work, NIR, LIBS, Raman and XRD techniques have been complementarily used to carry out a comprehensive characterization of a terrestrial analogue selected from the Chesapeake Bay Impact Structure (CBIS). The obtained data clearly highlight the key role of Raman spectroscopy in the detection of minor and trace compounds, through which inferences about geological processes occurred in the CBIS can be extrapolated. Beside the use of commercial systems, further Raman analyses were performed by the Raman Laser Spectrometer (RLS) ExoMars Simulator. This instrument represents the most reliable tool to effectively predict the scientific capabilities of the ExoMars/Raman system that will be deployed on Mars in 2021. By emulating the analytical procedures and operational restrictions established by the ExoMars mission rover design, it was proved that the RLS ExoMars Simulator is able to detect the amorphization of quartz, which constitutes an analytical clue of the impact origin of craters. On the other hand, the detection of barite and siderite, compounds crystallizing under hydrothermal conditions, helps to indirectly confirm the presence of water in impact targets. Furthermore, the RLS ExoMars Simulator capability of performing smart molecular mappings was also evaluated. According to the obtained results, the algorithms developed for its operation provide a great analytical advantage over most of the automatic analysis systems employed by commercial Raman instruments, encouraging its application for many additional scientific and commercial purposes.
