英文摘要	The Yutu-2 rover of the Chang'E-4 spacecraft observed many meter-sized shallow pits fully covered with small fragments, distinct from the typical rock-free impact craters with comparable sizes in the landing area. The unique morphology of the pits and the visible and near-infrared spectra of the fragments suggest that the fragments are broken pieces of impact melt-conglutinated regolith breccia projectiles, which were excavated from preexisting craters. The rareness of rock on the landing area surface suggests that the preexisting craters were probably small in size (e.g., <60 m in diameter), not large enough to penetrate the thick regolith (~12 m) and to excavate the beneath rock breccia and/or bedrock. The presence of the impact melts was confirmed by the glass-like spectra of some fragments with unusually high albedo and blue-green tint in the centers of the pits. These observations reveal the gardening and consolidating processes on the Moon. ©2020. American Geophysical Union. All Rights Reserved.
