Geologic map of the Hevelius region of the moon

January 9, 2023

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 topographic and other physical such as albedo, the reflectivity under full-Moon illumination. Such units are considered analogous to the rock-stratigraphic formations of terrestrial geology. By application of the principals of superposition and intersection, these rock units are arranged in order of relative age and grouped into time-stratigraphic units. Following terrestrial convention, the major time-stratigraphic units are designated systems, and their subdivision series; corresponding to these units are periods and epochs of time, respectively (Shoemaker, 1962,; Shoemaker and Hackman, 1962). The type localities of most the systems and series recognized to date are in the vicinity of Mare Imbrium. Correlation of many of the rock-stratigraphic units of the Hevelius region with the rock-stratigraphic units in the Mare Imbrium region is still uncertain.
