Lunar Surface as an Impact Counter, and its Stratigraphy

Abstract

In the preceding two chapters we gave a descriptive survey of the principal types of formations encountered on the lunar surface, as well as a brief account of the processes by which such individual formations could have originated. The aim of the present chapter will be to consider now the collective aspects of the observed surface features, their distribution and density over different types of lunar ground; and to draw some conclusions from this evidence which may throw light on the “partition function” of different processes considered in the preceding chapter, or on the conditions prevailing in interplanetary space.
