【摘要】：因携带水相关地质过程及环境的丰富信息,进而与生命起源密切相关,行星盐类研究受到大量科研工作者的关注。好奇号登陆之后,火星盐类研究取得了一些新进展。例如,在着陆区泥岩中发现了黄钾铁矾;在泥岩及泥岩砂岩的不整合接触面发现了石膏脉;在风沉积及原位沉积岩中发现了硝酸盐。此外,通过遥感手段,还发现火星新出现的斜坡沟渠可能是由含高氯酸盐高浓卤水冲击形成的。这些新进展再次表明了盐类对于火星科学的重要性。结合已有研究,凝练了火星盐类研究存在的重要科学问题,展望了中国未来火星探测研究。
[Abstract]:Because of carrying abundant information of water-related geological process and environment, and then closely related to the origin of life, the study of planetary salts has been concerned by a large number of researchers. New advances have been made in the study of Martian salts since the arrival of Curiosity. For example, jarosite was found in mudstone of landing area; gypsum vein was found on unconformable interface of mudstone and mudstone sandstone; nitrate was found in aeolian and in situ sedimentary rock. In addition, it is found by remote sensing that the new slope trench on Mars may have been formed by perchlorate containing high concentration brine. These new developments demonstrate once again the importance of salts to Martian science. The important scientific problems in the study of Martian salts are condensed, and the future research on Mars exploration in China is prospected.
