市领导会见中铁九局集团党委书记董事长张文杰一行_我的网站

一 |     9月20日，市委书记高键，市委副书记、市长王庆海会见中铁九局集团有限公司党委书记、董事长张文杰一行，地企双方围绕加快推进抚顺龙岗山雪上运动中心项目建设进行座谈交流。    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.                    。         　　高键代表市委、市政府对张文杰一行表示欢迎。他说，抚顺龙岗山不仅自然资源优越，而且生态环境优良，建设雪上运动中心项目前景广阔。希望中铁九局牢牢把握发展机遇，充分发挥央企优势，持续加强务实合作，全力投入到项目建设中来，携手实现共赢发展。充分发挥山水资源优势，积极谋划建设四季旅游项目，不断营造多元消费场景，实现从“一季火”到“四季热”，更好满足多样化、个性化的旅游消费需求。抚顺将持续优化营商环境，全力做好服务保障，为企业发展创造良好条件，共同推动合作项目早日建成达效。         　　张文杰表示，中铁九局集团高度重视抚顺龙岗山雪上运动中心项目，把该项目作为央企转型的重点项目进行推进，全力推动项目建设提速提质提效。同时，将持续深化多领域、全方位合作，在城市更新、基础设施建设等领域加强与抚顺对接交流，为抚顺经济社会高质量发展作出更多贡献。         　　市委常委、副市长杨洪波，中铁九局集团党委副书记曹子牧，中铁九局集团总部相关部门、辽宁区域总部等单位负责人参加。
