The French, Wenzhe Research Group of the School of Ground and Space has made important progress in the study of lunar soil characteristics and sample source areas in the landing area of Chang'e-5

In December 2020, China's "Chang'e" 5 successfully collected 1.

Affected by the impact, the lunar surface material (on geological time scales) will migrate, flip, mix and other phenomena

Figure 1 Geological background of the landing area: (a) Optical image of the geological unit (P58) of the landing area; (b) Multi-band pseudo-color composite images, red indicates low titanium content or high glass content, green indicates high iron content, and blue indicates high titanium content; (c) Local optical images of the landing site

The research team systematically analyzed

Figure 2 (a) Distribution of the main source impact crater (red dot) in Unit P58; (b) Distribution of impact craters within 1 km; (c) Optical image of Xu Guangqi's impact crater; (d) Statistical dating results of Xu Guangqi's impact crater

The research team further analyzed the source and evolution history of lunar soil in the Chang'e-5 landing area through the impact crater sputtering deposition process and thickness distribution model, combined with optical remote sensing data (Figure 2).

The above research results were published in JGR-Planets (cover paper) and EPSL (Figure 4), the international mainstream journals of planetary science, with Jia Bojun, a doctoral student in the School of Earth and Space, as the first author of the two papers, French Wenzhe as the corresponding author, doctoral students Liu Xiaofeng and Zhang Weiwei, and master student Tai Yushan participating in some of the research work
