原标题:英女王伊丽莎白二世灵柩将被运回伦敦据英国媒体9月13日报道,英国女王伊丽莎白二世的灵柩当天下午将从苏格兰首府爱丁堡启程,空运至伦敦诺霍特皇家空军基地。    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.                    。女王的女儿安妮公主将全程陪伴。灵柩抵达伦敦后,将移至白金汉宫。14日,伊丽莎白二世的灵柩将从白金汉宫移至伦敦威斯敏斯特大厅停留4天,民众可前往悼念。伊丽莎白二世的葬礼确定于当地时间9月19日在伦敦威斯敏斯特大教堂举行。当地时间9月8日,英国女王伊丽莎白二世在苏格兰巴尔莫勒尔城堡去世,享年96岁。(总台记者 康炘冬 陈林聪)返回搜狐,查看更多责任编辑:
