Geologic map of the Hommel quadrangle of the Moon

The Hommel quadrangle is in the southeast highlands of the earthside hemisphere of the Moon. The major geologic units are smooth and ridged terra materials, plains-forming materials and crater materials Mare material is absent. In the absence of extensive stratigraphic datum horizons, the geologic units were tentatively correlated with the type areas of the lunar geologic systems (Shoemaker and Hackman, 1962; Wilhelms, 1970) by means of a graded sequence of crater morphologies.
