Notes. Crater population dating results of the four sinuous rilles around the Chang’e-5 site and the mare unit of the site between this and previous studies. The crater counting areas for the BCC method are those of the buffer areas derived from the largest identified craters. The values in bold show the crater counting and dating results preferred in this study.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
