LUNAR CRATER POPULATIONS, EVOLUTION OF MEGAREGOLITH, AND INTERPRETATION OF LUNAR AND PLANETARY ROCK SAMPLES.

The present abstract combines model data from [4] with techniques for converting the sizefrequency distribution (SFD) of any given crater population into an estimate of the depth of material that has been extensively pulverized and converted into megaregolith materials. The basic idea of our technique begins with the log-incremental plot of any particular SFD crater-count curve, such as a curve for a sparsely cratered lunar maria, or a curve for a crater saturated lunar upland surface. 1.) This is not the same as saying that 100% of the area has been excavated by such craters, because many of the craters overlap earlier craters, so that some areas have not yet been impacted.
