Determination of lunar surface ages from crater frequency–size distribution

[摘要] Crater size –frequency distribution is one of the powerful techniques to estimate the ages of planetary surfaces,especially from remote sensing studies.This has been applied to images of the Moon obtained from Clementine mission in 1994.Simple techniques of measurement of the diameter of the craters (in pixels)are used and converted into linear dimensions.Among the several maria studied,the results of Mare Humorum and the central region of Mare Imbrium are reported.The results are compared with age estimates from other sources.
