中国科研团队完成了1∶500万《月球地质图》的编制工作[1]。这幅地图精准标注了13519个撞击坑、81个撞击盆地、14类构造和17种岩石类型等月球地质特征[1]。
基于嫦娥五号返回样品的测年数据，研究团队将月球火山活动的终点时间从约30亿年前刷新至20亿年前[1]，并首次将"爱拉托逊纪"划分为早、晚两个世，由中国自主月球样品测年数据锚定[1]。这一发现重构了月球地质年代表。
该月球地质图采用完全自主的图式、图例和配色标准，已获得中国地质学会团体标准认证，标准号为T/GSC 011-2025[1]。其中配色原则遵循"新浅老深"的设计理念，年轻地质特征呈现浅黄色，古老地质特征呈现深紫红色[1]。地图幅面尺寸约长280厘米、高120厘米[1]。这套自主标准体系将服务于后续火星、小行星等其他天体的地质编图工作[1]。
Chinese researchers have completed a 1:5 million scale Lunar Geological Map that comprehensively documents the Moon's surface features with independently developed cartographic standards [1]. The map precisely identifies 13,519 impact craters, 81 impact basins, 14 categories of structural formations, and 17 types of rock varieties [1].
Drawing on samples returned by the Chang'e-5 mission, the research team has refined understanding of lunar volcanic activity, pushing back the endpoint of volcanic processes from approximately 3 billion years ago to 2 billion years ago [1]. The map introduces the first subdivision of the Eratosthenian Period into early and late epochs, anchored by independent Chinese lunar sample dating data [1]. The physical map spans approximately 280 centimeters in length and 120 centimeters in height, designed at a 1:5 million scale [1].
The map employs fully autonomous symbolization, legend design, and color schemes developed under standard T/GSC 011-2025, which has received certification from the China Geological Society [1]. The color scheme follows the principle of "newer lighter, older darker," with younger geological formations rendered in pale yellow and ancient geological structures depicted in deep purple-red [1]. This independently developed cartographic framework is intended to serve as a foundation for future mapping projects of Mars, asteroids, and other celestial bodies [1].
