LARGE-SCALE EVOLUTION OF THE LUNAR SURFACE,
Abstract
The first part of the paper describes the relationship between the erosional stage of craters and the crater areal density. It is shown that class 2 and 3 craters are progressively more abundant as the crater areal density increases, while craters of class 4 and 5 are more abundant with decreasing crater areal densities. The second part of the paper presents a method for relatively dating large lunar areas. In the final part of the paper a geological model is developed in order to explain age differences in the terrae. The model calls for 'rejuvenation' of lunar terrains, caused by the seismic waves and ballistic sedimentation resulting from large impacts. The area surrounding Mare Orientale is cited as an example of a terrain so affected.
