A lunar surface accretionary particle flux (experimentally determined from consortium sample 12054) is used to incorporate the effects of accreta into the erosion scenario for the lunar surface in order that the approach to lunar equilibrium microtopology might be established. Over the specific size ranges the effects of accretionary particles dominate over the effects of erosion processes such as impact cratering and solar wind sputtering. The results of calculations are presented which give the times taken for accreta to establish (1) areal coverage, (2) complete crater pit volume infilling, and (3) single particle obscuration. These effects are then incorporated with crater impact erosion and solar wind sputter erosion in order to determine crater equilibrium conditions. Also investigated is the build-up of accreta equilibrium populations.
