英文摘要

Chang’e-5 successfully returned ∼1,731 g of lunar samples on December 17, 2020. We systematically studied the morphology and morphometry of craters surrounding the Chang’e-5 site based on high-resolution images. A key ejecta source crater database was produced, incorporating their morphometrical parameters, excavation depth, target rock types, and ages from either crater counting, crater morphology or degradation methods. We found that 1) the regolith at the Chang’e-5 site is ∼4-6 m thick, 2) ejecta are primarily from five proximal craters, including Xu Guangqi, dominantly with ages <200 Ma; 3) distal materials are mainly from Harpalus, Copernicus, Aristarchus, and Mairan G craters; 4) the drill samples are likely to be mainly from Impact Crater (IC)-261 and IC-265 particles at the top and the contribution of Xu Guangqi increases with depth; 5) the ejecta of Xu Guangqi would buried pre-existing materials but probably overturned by post-impacts.
