摘要
阿耳特弥斯勘探区是一个地质复杂的区域,可能蕴藏着月球上一些最古老且尚未研究的物质。我们审查了 "阿耳特弥斯 "三号候选着陆区 "连接山脊"、"沙克尔顿附近的山峰"、"莱布尼茨贝塔高原"、"de Gerlache Rim "和 "de Gerlache Rim 2 "内六个潜在的 "阿耳特弥斯 "着陆点(001、004、007、011、102 和 105)。利用 Kaguya 光谱剖面仪的矿物数据确定了每个着陆点的平均岩性成分。针对每个潜在着陆点的返回样本,讨论了可能获取的地质材料、其年龄和重要性,以及辐射年代测定仪的适当应用。对阿耳特弥斯勘探区的返回样本进行年代分析,将有助于确定月球撞击通量曲线,确定月球地质历史上关键事件的绝对时间,并揭示分化月球体的地质多样性。
Lithologies and Chronologic Opportunities of Materials to Be Returned From the Artemis Exploration Zone
The Artemis exploration zone is a geologically complex region likely to host some of the oldest and as-yet-unstudied materials on the Moon. We review six potential Artemis landing sites (001, 004, 007, 011, 102, and 105) within candidate Artemis III landing regions ”Connecting Ridge,“ “Peak Near Shackleton,” “Leibnitz Beta Plateau,” “de Gerlache Rim,” and “de Gerlache Rim 2.” Kaguya Spectral Profiler mineral data were used to determine the average lithological composition at each landing site. Potentially accessible geologic materials, their ages and significance, and appropriate application of radiometric chronometers are discussed in reference to return samples from each potential landing site. Chronological analyses of return samples from the Artemis exploration zone will enable the anchoring of the lunar impact flux curve, determine the absolute timing of pivotal events in lunar geologic history, and reveal the geological diversity of the differentiated lunar body.
期刊介绍:
The Journal of Geophysical Research Planets is dedicated to the publication of new and original research in the broad field of planetary science. Manuscripts concerning planetary geology, geophysics, geochemistry, atmospheres, and dynamics are appropriate for the journal when they increase knowledge about the processes that affect Solar System objects. Manuscripts concerning other planetary systems, exoplanets or Earth are welcome when presented in a comparative planetology perspective. Studies in the field of astrobiology will be considered when they have immediate consequences for the interpretation of planetary data. JGR: Planets does not publish manuscripts that deal with future missions and instrumentation, nor those that are primarily of an engineering interest. Instrument, calibration or data processing papers may be appropriate for the journal, but only when accompanied by scientific analysis and interpretation that increases understanding of the studied object. A manuscript that describes a new method or technique would be acceptable for JGR: Planets if it contained new and relevant scientific results obtained using the method. Review articles are generally not appropriate for JGR: Planets, but they may be considered if they form an integral part of a special issue.
