Professor Zongcheng Ling et al. published one research paper in Planetary and Space Science. This work presented a comprehensive study of the composition, mineralogy, and chronology of the basaltic and non-mare units in Von Kármán crater obtained the spatial distribution characteristics of the chemical composition of Fe, Ti, Mg# and Th, and the relative content of clinopyroxene and orthopyroxene, and present a geological map of the landing site, which reveals the geologic history of the landing region. The study showed a difference in composition between the Lunar mare and the non-mare, and there is a complex mixing effect with the non-mare materials (the landing area is mainly affected by the Finsen crater ejecta). Mare basalts with low-Ti composition and model ages of ~3.7 Ga and ~3.6 Ga; non-mare materials have Mg-rich pyroxene, and Finsen crater materials (and Finsen ejecta) have higher Ca/Fe ratios than other parts of the rim of Von Kármán crater. We also present a geological map of the landing site, which reveals the landing region's geologic history and will help guide the CE-4's Yutu-2 rover's surface exploration route.
