Description

The purpose of this map summarizes the current state of lunar geologic knowledge developed by the U. S. Geological Survey’s systematic lunar mapping program. The map provides a stratigraphic framework to be used for developing new theory and for determining the regional significance of surface exploration results. The geologic summary which accompanies the map gives the major genetic and historical conclusions which stem from the work. The map explanation provides the descriptive details that led to these conclusions. An accompanying pamphlet discusses the rationale, methods, and nomenclature of lunar stratigraphy. The work is based both on results of the telescopic mapping program and on data from the unmanned lunar exploration program, particularly the regional coverage of Lunar Orbiter IV.
