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

一 |     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.                    。    AI摘要      亲绿智库民调显示江启臣支持度与看好度均大幅领先何欣纯，卢秀燕施政满意度优于林佳龙；传其拟参选2028，本人回应将专注完成市长任期。         中国台湾网8月17日讯 有岛内亲绿智库17日公布台中市市长选战最新民调称，结果显示，中国国民党台中市市长参选人江启臣以42.8%的支持度，领先民进党台中市市长参选人何欣纯的36.1%。

二 | 在当选看好度方面，江启臣48.2%，何欣纯23.6%，江启臣看好度大幅领先何欣纯24.6%。         图注：卢秀燕日前接任江启臣竞选总部主委。    此外，针对江启臣担任台立法机构副负责人以来的表现，45.5%受访者表示满意，26.6%不满意，27.9%无明确意见。    除上述结果外，本次调查还涉及国民党籍现任台中市市长卢秀燕，与民进党籍前任台中市市长林佳龙之间的施政满意度比较。统计显示，卢秀燕的整体施政满意度达53.9%，不满意度为36.5%。针对“卢秀燕与前市长林佳龙，谁的表现比较好”，有45.5%受访者认为卢秀燕做得更好，高于选择林佳龙的34.5%。

三 |     另据台媒早前报道，国民党民代叶元之上周曾爆料，台中市市长卢秀燕将于2026年12月25日卸任当日，正式宣布参选2028年台湾地区领导人，是势在必行的布局。对此，卢秀燕本人随后亲自回应，身为现任台中市市长，她会坚守岗位、将任期做好做满。
