Summary

The surface of the moon is heterogeneous. Surface materials are classed on the basis of telescopic observations into units each having a limited range of physical properties such as topography, visible under low-illumination and albedo, the reflectivity under full-Moon illumination. Such units are considered analogous to the rock-stratigraphic formations of terrestrial geology. By application of the principles of superposition and intersection, these rock units are arranged in order of relative age and grouped into time stratigraphic units. Following terrestrial contention, the major time-stratigraphic units are designated systems, and their subdivisions, series; corresponding to these units are periods and epochs of time, respectively [...]

Purpose

Digitized 1:1,000,000-scale geologic map of the (LAC-93) Mare Humorium 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.
