基于第一性原理和实验室结果，提出了一个描述和评估陨石撞击月球表面长期效应的模型。的陨石坑表面和伴随的风化层的演变进行了计算，并与观测和分析的月球轨道器的照片。这表明，大多数陨石坑是撞击的起源，但在月球的不同单位和地区的表面的表观年龄的巨大差异意味着内生过程也必须是活跃的，可能是从前寒武纪开始的时间，也许，最近的几百万年前。
A model based on first principles and laboratory results is presented for describing and evaluating long term effects of meteoritic impact against the lunar surface. The evolution of the cratered surface and concomitant regolith is calculated and compared with observations and analyses of Lunar Orbiter photographs. It is indicated that most craters are of impact origin, but gross differences in the apparent ages of surfaces in various units and regions of the moon imply that endogenic processes also must have been active, probably since the beginning of Precambrian time and, perhaps, as recently as a few million years ago.
