| 摘 要： | 地球和月球很可能是通过大撞击形成的。在行星地质学中,研究月球的地质-构造现象,对了解月球、地球乃至太阳系的形成与演化历史都有很大帮助。月球的构造分为深部构造与月表构造,寻找它们在分布或成因上的关系,可以为月球甚至地月系的起源和演化历史提供重要参考。利用LROC的宽视角影像数据以及LOLA数据提取解译月表构造,结合深大断裂进行观察分析,并对月球的撞击盆地进行统计,最后以静海地区为例分析构造分布特征,发现月球的质量瘤盆地中具有环状分布的月岭,外侧具有近环状分布的深大断裂,自前酒海纪至酒海纪,具备上述特征的质量瘤盆地占总撞击盆地的比例突然有一个很大的提升,且静海地区西部具有该构造分布特征。推测该特征与撞击、月海沉降等有关,且在酒海纪与雨海纪期间月球有较多的月海玄武岩分布,由此判断静海西部存在质量瘤,发生过撞击与月海沉降。

| Abstract: | The Earth and the Moon are likely to be formed by large impacts. In planetary geology, studying the geological-tectonic phenomenon of the Moon has been of great help to understand the history of the formation and evolution of the Moon, the Earth and even the solar system. The lunar structure is divided into deep structures and lunar surface structures, whose relationship in distribution or genesis is studied to provide an important reference for the origin and evolution history of the Moon and even the earth-moon system. By synthesizing LROC wide-angle image data and LOLA data, this paper extracts and interprets the structure of the lunar surface, observes and analyzes the deep and large faults, and works out the statistics of the impact basin of the Moon. Besides, by analyzing the structural characteristics of the Tranquilitatis area, it is found that the lunar mascon basin has ring-shaped dorsa, and its peripheral has nearly ring-shaped deep faults. Moreover, from pre-Nectarian to Nectarian period, the proportion of mascon basins with such features to all impact basins dramatically increased. The western Tranquilitatis area has such structural distribution. It is inferred that the characteristics of this structural distribution are related to the impact, lunar mare subsidence, etc. There are many lunar basalt distributions during the Nectarian and Imbrian period. It is believed that there used to be impacts and lunar mare subsidence, which result in mascons in the western Tranquilitatis area. |
