Summary
Material exposed on the surface of the moon is heterogeneous. The albedo and other physical characteristics that have been determined with the use of optical and radio telescopes vary from one part of the moon to another, and the variations are partially correlated with differences in topography . Discontinuities in the areal variation permit the surfaces material to be divided into map units, each exhibiting a limited range of topographic characteristics. Each map unit is further characterized by a distinctive pattern of distribution, and the patterns of certain units are in places superimposed on the patterns of other units. From the relations of superposition it is possible to determine the sequence in which the units were formed.

Digitized 1:1,000,000-scale geologic map of the LAC-75 Letronne region of the Moon. Originally mapped on Lunar Base Chart USAF-ACIC imagery. The scanned map sheet was imported into ArcMap and georeferenced to the more current 2013 global WAC mosaic basemap. Contacts and geologic units were digitized and attributed based on type and unit name.
