蒙斯伦克是月球上普罗塞勒姆大洋星上的一个大型火山杂岩，也是中国嫦娥五号样品返回任务的候选着陆点。为了更好地了解该地区的地质情况，为嫦娥五号任务提供进一步的支持，我们利用多源遥感数据对蒙斯伦克地区的地形、地貌、成分和地层进行了全面的研究。结果表明，Rümker高原海拔200~1300 m，75%的高原坡度小于3°，基线长度为30 m。穹顶是蒙斯Rümker最突出的火山地貌，共识别出22个穹顶，分为两种类型，可能代表了不同的火山活动阶段。光谱分析表明，Mons Rümker被低钛玄武岩覆盖，镁铁质矿物以高钙辉石为主，但也有高地物质与玄武岩混合的迹象。Mons Rümker有三个主要玄武岩单元，其绝对模式年龄分别为3.71、3.58和3.51 Ma。陡峭的圆顶可能是高原上最年轻的火山地貌，有迹象表明它们在埃拉托塞尼纪之前是活跃的。编制了研究区新的地质图，并用来解释和讨论该地区的地质演化。最后，我们提出了嫦娥五号任务的两个候选着陆点。
Mons Rümker is a large volcanic complex in Oceanus Procellarum on the Moon and is a candidate landing site for China's Chang'E‐5 sample return mission. We conducted a comprehensive study of the topography, geomorphology, composition, and stratigraphy of the Mons Rümker region with multisource remote sensing data in order to better understand the geology of the region and provide further support for the Chang'E‐5 mission. The results show that the Rümker plateau stands 200–1300 m above the surrounding mare surface and 75% of the plateau has a slope of less than 3° at a baseline length of 30 m. Domes are the most prominent volcanic landforms in Mons Rümker and a total of 22 domes were identified and divided into two types that may represent different stages of volcanic activity. Spectral analyses indicated that Mons Rümker is covered by low‐Ti basalt and the dominant mafic mineral is high‐calcium pyroxene, though signs of mixing of highland materials and basalt have been found. Mons Rümker has three main basalt units, and their absolute model ages are 3.71 Ga, 3.58 Ga, and 3.51 Ga, respectively. Steep‐sided domes could be the youngest volcanic features on the plateau with indications that they were active until the Eratosthenian. A new geologic map of the study region was produced and used to interpret and discuss the geologic evolution of the region. Finally, we propose two candidate landing sites for the Chang'E‐5 mission.
