Abstract:

The geological map of the moon, also known as the geological map of the lunar surface or the lunar surface geological zoning map, shows the characteristics of the distribution of different kinds of matter in the lunar surface in different periods. Mapping the lunar maps and atlases is one of the most important works of lunar exploration and scientific research. Through full analysis of the first lunar geological map finished 50 years ago and the recently completed Sinus Tridum, Copernicus geological map,and using Chang’e I, II CCD data, and digital elevation, IIM and LRO data,we selected Serenitatis-Tranquillitatis area as the study area and completed the first Serenitatis-Tranquillitatis area lunar geological map, in which the geological background, structure type, stratigraphic age, material unit, basin structure, pyroclastic distribution, and basalt thickness are the main elements. We developed a systematic mapping engineering plan, combined with domestic technical standards and specifications of digital geological mapping and established our own lunar and planetary geological mapping standards, specifications and mapping processes. The experience can be extended to geological mapping of Mars and Venus as the technical foundation.

Key words: geological map, Serenitatis-Tranquillitatis area, Chang’e, Sinus Iridum
