CTOnews.com, November 2, whenever you look up at the moon at night, have you ever wondered how many kinds of rocks there are on the moon? According to the official website of Shandong University, the world's first 12.5 million lunar rock type distribution map led by Shandong University was released on October 31.

Comprehensive information of lunar rocks

1Rod 2.5 million lunar rock type distribution map English version thumbnail from 2012 to 2022, supported by the exploration data of the Chang'e Project, led by Ouyang Ziyuan, academician of the Chinese Academy of Sciences, and Liu Jianzhong, researcher of the Institute of Geochemistry of the Chinese Academy of Sciences, Shandong University as the lead unit In conjunction with the Institute of Geochemistry of the Chinese Academy of Sciences, Jilin University, the Chinese Academy of Geosciences, the China University of Geosciences (Beijing) and the Institute of Geographical Sciences and Resources of the Chinese Academy of Sciences, based on the classification methods of lunar samples and the information obtained by lunar remote sensing in recent years, a classification system of lunar surface rocks is established, and the characteristics and environments of different rocks are summarized. At the same time, through the establishment of lunar rock classification index, mapping process and method, legend, and using GIS platform, the first lunar rock type distribution map of 12.5 million lunar rocks in the world is completed.

The lunar surface materials are divided into three types: lunar sea rocks, non-lunar sea rocks and special rocks, and a total of 17 rock types are expressed. Among them, 5 types of lunar sea basalts (including 923 lava flow units), 7 types of non-lunar sea rocks (including 1210 lithologic units and 434 lithologic outcrops) and 5 types of special rock outcrops (including 115lithologic units and 779 lithologic outcrops).

The map is a comprehensive expression of the current material composition distribution and related knowledge on the lunar surface, and can be used as the basic data for lunar scientific research, exploration mission planning, sampling and returning to the target area. it can also provide a reference for the mapping of other rocky terrestrial planets in the future. The 1RU 2.5 million lunar rock type distribution map is divided into Chinese and English versions, which will be officially released by the Geological Publishing House in paper and electronic versions.

The research results were published on October 31 in the international comprehensive journal Science Bulletin (Zone 1 of the Chinese Academy of Sciences, the latest impact factor 20.577).
