＂The moon is color!＂Researchers of the Chinese Academy of Sciences tell how to prepare the latest lunar ＂Geological Encyclopedia＂
On April 21, the Chinese Academy of Sciences held a press conference in Beijing to release the world’s first high -precision moon geological atlas, a colorful moon appearance.
Conference site
It is reported that the atlas include “1: 2.5 million Monthly Monthly Geological Atlas” and “1: 2.5 million Monthly Monthly Geological Atlas” (Chinese and English) and use multiple colors to distinguish the changes in the moonlight and moon of the moon.Among them, “1: 2.5 million Monthly Geological Atlas” contains “1: 2.5 million Monthly Monthly Monthly Month”, “1: 2.5 million monthly rock type distribution map” and “1: 2.5 million monthly outline of the month”, “1: 1:2.5 million amplitude geological atlas “” 30 moon standard geological maps.
When it comes to why scientists gather the research results of the world and use such a full month map in the past ten years, Liu Jianzhong, a researcher at the Institute of Geochemical Research of the Chinese Academy of Sciences, said that the moon’s geological map is the rock phase, rock nature, and “stratigraphy, stratigraphy, and” stratigraphy, and “stratigraphy, stratigraphy, and” stratigraphy.”The comprehensive formation of the age, geological structure, magma activity, and mineral distribution is the great successor that integrates the results of the moon geological, geological chemistry, earth physics, and surveying and mapping science.Scientific research and future moon exploration, moon base location and construction are indispensable.
Moon meter based on full moon map
Internationally point of view, the major spaces and organizations of various spaces take the moon as the focus of detection.However, from the beginning of the 1960s, to the end of the 1970s, the U.S. Geological Agency completed a variety of lunar geological maps of the proportion of the lunar, and systematically integrated the lunar exploration results in the Apollo era.But the geological map covered the whole month was only 1: 5 million geological maps completed in the late 1970s.Although the unified geological map of 1: 5 million was released in April 2020, it was only a reorganization of the predecessors, which means that so far, there is no new higher -precision full -month geological map release.
In such an international background, in early 2012, Academician Ouyang Ziyuan, an academician of the Chinese Academy of Sciences, proposed the idea of 1: 2.5 million monthly digital geological map editing and research, establishing a moon geological space database, forming a comprehensive integrated result of the establishment of a classic classic, and building a comprehensive integrated result of the establishment.The new starting point of the basic theoretical research of the moon’s geology and structure, establish a new framework of land -like planet evolution with an exterior and external power geological effects, and promote the leapfrog development of Chinese lunar exploration and lunar scientific research.
Introduction of Liu Jianzhong at the press conference site
Since 2012, with the support of the “13th Five -Year Plan” of the Chinese Academy of Sciences, the “Minimal Science Research Plan” project, the special project of the Ministry of Science and Technology, the National Natural Fund Commission, and the National Publishing Fund project, etc.Academician Ouyang Ziyuan and Liu Jianzhong organized scientists and charters of Jilin University, Shandong University, China University (Beijing), the Institute of Geological Research of the Chinese Academy of Geosciences, and the Institute of Geographical Sciences and Resources of the Chinese Academy of Sciences.
According to the convention of geological maps and research, two types of diagrams are generally compiled. Geological diagrams and constructor outlines are generally compiled.The moon is a celestial body with internal and external power and evolving. In the early stage, the power is dominant, and the external power is mainly in the later period. At present, the moon’s surface is mainly the product of external power geology.Geological effects are the decisive factor that laid the basic framework of the moon.
In order to truly reflect the records left by the internal and external dynamic effects of the moon, scientific researchers have added a rock type distribution map to express the characteristics of the internal power geological role of rock composition and the history of thermal evolution and chemical evolution, and the geological map focuses on the focus of the geological map.Express the evolution of impact structures and construction formed by external power geology.Therefore, the planned all -monthly geological series charts include three categories: geological maps, constructor outlines, and rock type distribution maps.
Editing work is a systematic project. In order to work smoothly and efficiently, holding a coordinated seminar is an important means among work promotion.From the first screening meeting on May 9, 2012, by October 9, 2021, a total of 39 large -scale seminars were held.
“大型会议就是需要邀请专家，召开正式的研讨会。而团队内部召开的小型讨论会更多更为频繁。”在编图过程中，开展了广泛的科学咨询，其中国内专家80余位，国外More than 20 experts.At the same time, in order to achieve exquisite preparation effects, at the beginning of the project, Liu Yajun, an editor of Geological Publishing House, was hired as a member of the consultant expert group to participate in the editing and research of the moon’s geological series.
Until October 9, 2021, the results of the drawing were identified by the experts of Wang Chengshan, an academician of the Chinese Academy of Sciences, and concluded that “reaching the international leading level.”The main picture of the atlas identifies and marked the 12341 impact pits, 81 impact basins, 17 types of rock types, and 14 types of constructor throughout the month, and established a unified basis for building sub -categories.
Reporter interview Liu Jianzhong
As the only research institution of the Chinese Academy of Sciences in Guizhou Province, Liu Jianzhong stated that the next step of planning, led by the Institute of Geochemistry of the Chinese Academy of Sciences, will accelerate the preparation of higher precision moon geological maps on the one hand.The “Western Calculation” policy will vigorously develop new quality productivity, and take the establishment of a digital moon cloud cloud platform as the starting point.Work, then change the research paradigm of planet science, and promote the leapfrog development of planet science.
