【摘要】：月海盆地作为月球表面重要的地貌单元,分析其玄武岩喷发历史和构造作用,对于了解月球演化有着重要的意义。文中以澄海和静海两个相连通盆地为研究区,通过对LRO的DEM数据进行处理,获得两个月海的地形特征。基于Clementine多光谱数据处理,提取TiO2、FeO含量和成熟度分布图。经过对嫦娥一号CCD影像数据并结合LRO和LO全色波段影像的解译,提取了研究区126条月岭和114条月溪,并对比Cle-mentine提取的重力分布图,对其展布形式进行研究。综合分析结果表明,两个盆地虽然相邻连通,但岩性和构造分布有着明显的差别,玄武岩喷发不同期次界限明显,且澄海玄武岩年龄普遍晚于静海,相通处玄武岩与静海北部玄武岩同源。澄海中的线状构造展布形式与静海中的明显不同,呈现出一定规律,与质量瘤的有无及重力展布形式有关。
[Abstract]:As an important geomorphological unit on the lunar surface, Yuehai Basin is of great significance for understanding the evolution of the Moon by analyzing its basalt eruption history and tectonic processes. In this paper, two connected basins of Chenghai and Jinghai are taken as the study area, and the topographic characteristics of the two lunar seas are obtained by processing the DEM data of LRO. Based on Clementine multispectral data processing, TiO2,FeO content and maturity distribution maps were extracted. Based on the data of Chang 'e-1 CCD image and the interpretation of LRO and LO panchromatic images, 126 Yueling and 114 Yuexi were extracted in the study area, and the distribution of gravity map extracted by Cle-mentine was compared and its distribution pattern was studied. The comprehensive analysis results show that although the two basins are adjacent to each other, the lithology and tectonic distribution of the two basins are obviously different, the boundary of basalt eruption is obvious at different periods, and the age of Chenghai basalt is generally later than that of Jinghai. The basalt is homologous with the northern Jinghai basalt. The distribution form of linear structure in Chenghai is obviously different from that in static sea, which is related to the existence of mass nodule and the distribution of gravity.
