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.                    。    12月3日，抚顺市“聚才智·强三农”院地企协同创新联合体宣告成立。         　　13年来，省农科院与抚顺市：          　　开展实施各类科技服务项目122项；          　　累计引进示范推广新品种349个、新技术334项；          　　建立示范基地272处；          　　示范推广面积29.7万亩；          　　辐射推广面积110万余亩。
