1:250万月球全月构造纲要图

The 1:2,500,000-scale global tectonic map of the Moon

月球构造演化受到以岩浆活动为主的内动力和以陨石撞击为主的外动力地质作用共同驱动.月球构造纲要图系统表达了月球构造和构造单元时空分布的信息,是当前月球构造和演化历史知识的综合.以嫦娥工程数据为基础,充分利用国际上其他月球探测数据和研究成果,建立了基于动力学机制的月球构造分类体系.根据月球构造的动力学成因机制,将其划分为外动力成因和内动力成因两大类,并结合形貌特征,进一步细分为线性构造和环形构造.综合地球物理、地球化学、地形和构造分布等特征,划分了月球的五大构造单元.通过制定月球构造纲要图编制的标准、流程、方法和图示图例,应用地理信息平台,完成了世界首幅1∶250万比例尺的月球全月构造纲要图.月球构造纲要图是科学研究、探测规划和着陆点选择的基础资料,同时也为其他天体构造图的编制提供了参考.

The tectonic evolution of the Moon is driven by both endogenic(e.g.,magmatism)and exogenic(e.g.,meteorite impact)forces.A tectonic map of the Moon provides key information about the spatiotemporal distribution of structures and tectonic units.Although the Moon has no plate tectonics,its surface can be divided into different terranes due to the uneven evolution[1].We define these terranes as tectonic units.Structures,such as craters and faults,are the basic elements of the tectonic units.As a synthesis of current knowledge on lunar tectonics and evolutionary history,lunar tectonic maps are a fundamental resource for scientific research,exploration planning,and landing site selection[2].
