英文摘要The microwave signal has the penetration capability, which provides a potential chance to improve understanding of the mare deposits and the formation process of Mare Australe, a complex, extensive, and poorly understood region on the Moon. In this paper, the Chang'E-2 microwave radiometer (CELMS) data were selected and processed to evaluate the microwave thermal emission features of the mare deposits in Mare Australe. After comparison, the dT(B) map at 3.0 GHz is employed. The results are as follows. (a) The possible cryptomare is much more extensive in Australe region than that identified with optical data. (b) The basaltic volcanism is re-understood as three major episodes. (c) The high dT(B) anomaly is interpreted as the location of the vent areas in the mare patches. (d) The K-means algorithm was first used to process the CELMS data, and the identified linear and ring structures indicate some important information about the formation processes of Mare Australe. These special findings will be of fundamental significance to better understand the basaltic volcanism and the evolution of the lunar surface. Plain Language Summary In Chinese lunar exploration project, a microwave radiometer (CELMS), which operated at 3.0, 7.8, 19.35, and 37.0 GHz channels, for the first time, was aboard the Chang'E-1/2 satellites to measure the microwave thermal emission of the lunar regolith. The data have the highest spatial resolution in passive microwave domain, and the penetration depth of the used microwave can be up to several meters. Moreover, the CELMS data have been proved to be fairly sensitive to the substrate composition. This provides a potential way to study the possible cryptomare and the hidden deposits and structures overlaid by the impact ejecta. This is also the motivation for us to study Mare Australe, which is a complex, extensive, and poorly understood region located in the southeast hemisphere of the Moon. Key Points
