Summary
The surface of the Moon is heterogenous. Local surfaces can be classed on the basis of telescopic observations into units, each having a limited range of physical properties such as topograhpy, visible under low illumination. The properties of such surface units are considered to represent properties of under lying materials, so that the surface units corespond to underlying rock units which are analogous to the rock-stratigraphic formations of terrestrial geology. These rock units are arranged in order of relative age and grouped into time stratigraphic units by application of the concepts of superpositon and intersection, and by their apparent modification of properties with time. Following terrestrial convection, the major time-stratigraphic [...]
Summary
The surface of the Moon is heterogenous. Local surfaces can be classed on the basis of telescopic observations into units, each having a limited range of physical properties such as topograhpy, visible under low illumination. The properties of such surface units are considered to represent properties of under lying materials, so that the surface units corespond to underlying rock units which are analogous to the rock-stratigraphic formations of terrestrial geology. These rock units are arranged in order of relative age and grouped into time stratigraphic units by application of the concepts of superpositon and intersection, and by their apparent modification of properties with time. Following terrestrial convection, the major time-stratigraphic units are designated systems; the three systems recognized to date are Imbrian, Eratosthenian and Copernican. The type localities of the systems are in the vicinity of Mare Imbrium (Shoemaker, 1962; Shoemaker and Hackman 1962).
Digitized 1:1,000,000-scale geologic map of the LAC38 - Seleucus Quadrangle 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
