Re-understanding geomorphological features in Change-5 sampling region based on multi-scale roughness model

Chang'e-5 (CE-5) mission was successful to return samples up 1.8 kg from the northeastern part of Rumker region, Moon. These can provide new understandings for basaltic volcanism northern Oceanus Procellarum. Therefore, terrain-related analysis region will become a hotspot in recent and latter studies. As typical surface analyzing method, multiscale roughness has been used planetary studies long time. However, fewer topographic are applied region. The visual interpretations directly digital elevation models (DEMs) or images potentially cause controversial results. To way reunderstanding geomorphological features we investigate method extract signatures by using wavelet-based V-system degree 1. Based on these signatures, hectometer- kilometer-scale calculated mapped. textural changes Our results demonstrate that: 1) Most younger mare units show lower textures following with scale increases. Especially at kilometer scales, understanding is given Im1 Em1 based statistical variations geologic units; 2) compared obtained optical data, maps recognize wrinkle ridges reevaluated changes.
