The compilation of the lunar digital geological map and a discussion on the tectonic evolution of the moon

Abstract: The compilation of the Lunar Digital Geological Map was based on the scientific exploration data obtained by Chang’E-1 and Chang’E-2 and other lunar geological data as well as research?results. According to the material compositions, structure elements and the information of geochronology of the Moon, the authors compiled the Lunar Geological Map at a scale of 1∶2500000 and established spatial database by using the ArcGIS platform. The authors developed a mapping programs, processes and legends for the Lunar Digital Geological Map, and established a spatial database based on Geodatabase model by compiling and investigating geological map of the typical region, which can effectively update and manage the Digital Geological Map and thus lay the foundation for the geological comprehensive study of the Moon, the geological mapping of the whole Moon, and also the geological mapping of other celestial bodies in the future. This paper also deals with the tectonic evolution of the moon on the basis of summarizing the compilation of the Lunar Digital Geological Map and comprehensive research on a large number of lunar geological data.
