China unveils refined lunar map, empowering future moon exploration_我的网站

A |     A Chinese research team has completed an updated geologic map of the entire moon featuring a scale of 1:5 million, the Institute of Geology, Chinese Academy of Geological Sciences (IGCAGS), said on Thursday.    Representing a significant scientific iteration from the 2024 version, this map effectively rewrites the moon's geologic history based on the latest research findings. "The lunar geologic history has indeed been rewritten -- more precisely, refined and systematized," said Yang Zhiming, director of the IGCAGS.    Specifically, a primary achievement of this update is the recalibration of the moon's ancient geologic eras. The new map systematically updates the age boundaries of the moon's three ancient geologic periods, namely the Aitkenian, Nectarian and Imbrian periods, drawing on recent advances in international chronology.    Crucially, Chang'e-5 samples confirmed volcanic activity on the moon as recently as 2 billion years ago, extending its geologic lifespan by 1 billion years from the previously accepted 3 billion years. This independent dating data has now become a cornerstone of the global lunar geologic timescale.    Highlighting these spatial discoveries, the new global lunar geologic map is the first comprehensive canvas to bear exclusive findings from the Chang'e-6 mission. "The lunar samples and this map will provide a new starting point for scientific discussions regarding the lunar far side," said Jin Ming, an associate researcher at the IGCAGS.    The map details the age of young mare basalts on the lunar far side obtained from the Chang'e-6 samples, recording the region's volcanic history. Furthermore, it reveals that KREEP rocks, enriched with rare earth elements and other strategic resources, are far more continuous and abundant in the Oceanus Procellarum than previously estimated. This discovery, achieved by eliminating spectral noise, prompts a systemic reevaluation of the moon's early magma ocean crystallization and internal thermal evolution.    Beyond its scientific data, the 2.8-by-1.2-meter map introduces a proprietary cartographic standard. Identifying over 13,500 impact craters and 81 basins, it employs a unique color scheme rooted in geologic logic and traditional Chinese aesthetics, following a "lighter for younger, darker for older" principle.    Furthermore, this standard will also be applied to future geologic mapping of Mars and asteroids, ending reliance on foreign standard systems.    "This goes beyond showcasing technological soft power. This standard will be extended to future planetary geologic mapping, establishing an independent intellectual property framework for China's deep space exploration," Yang said.                    。    本报讯为贯彻落实习近平总书记关于法治是最好的营商环境重要论述、八五普法规划、关于组织开展民法典主题宣传的部署要求，近日区委宣传部、区委法制建设委员会守法普法协调小组、区司法局，以优化法治化营商环境为重点，组织全区持续深入开展民法典系列普法宣传，将法律知识送到群众身边，将居民法律疑难问题解决在家门口。         　　区委法制建设委员会守法普法协调小组按照谁执法谁普法，谁服务谁普法的普法责任制要求，多部门联合开展高频次、多样式的普法宣传活动。通过送法进机关、进社区、进乡村、进企业、进校园、进单位，并结合政务公开日集中宣传活动，设置咨询台，悬挂条幅，发放《宪法》《中华人民共和国民法典》等宣传手册、消防安全知识手册、禁毒宣传单、法律援助联络卡以及定制的法制元素环保袋等宣传品。
