【摘要】：线性构造是指月表以线状延伸的构造现象,与环形构造相比,线性构造能够反映全月球或者区域性的构造特征与应力状态,甚至能够反映月球内部的地质信息。月岭作为月表最常见的线性构造类型之一,分布数量最多且具有一定的分布规律,也一直是国内外关于月表构造研究的重点。月海盆地因其与月表大部分线状构造有着明显的共生关系,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。本论文的主要内容及成果如下： (1)利用国内外多源遥感数据并结合相关文献对月表的线状构造进行了分类和解译,将月表线状构造分为了10种,并分别对各类成因进行了综合分析。通过利用LRO的DEM数据重点对月岭剖面并进行了构造分析,认为月岭主体为逆冲断层叠加牵引褶皱的挤压构造形成机制。 (2)关于月岭构造的动力成因,前人多用月海盆地沉降叠加月球热能收缩解释月岭的成因,但它无法解释盆地中央月岭呈近南北向的优选方位,这种现象可能是受到近东西向区域性挤压应力的影响,与潮汐力对月球中低纬度区域的应力作用状态相符,推测潮汐力可能是其形成的主因；综合利用嫦娥一号CCD影像数据、Lunar Orbiter和LRO影像数据,解译识别出月球正而中低纬度1464条月岭,对其进行方向统计结果表明,月岭整体走向也与Melosh预测的在潮汐力作用下形成的构造样式相似。由此推测,月岭的展布与潮汐作用力具有很强的相关性,进而,进一步论证了月岭的形成与潮汐力有关。 (3)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Ti02、FeO百分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clementine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]:Linear structure refers to the linear extension of the lunar surface. Compared with the annular structure, the linear structure can reflect the tectonic characteristics and stress state of the whole moon or region, and even reflect the geological information of the lunar interior. As one of the most common linear structures on the monthly surface, Yueling has the largest number of distributions and has a certain distribution law, which has always been the focus of the research on the monthly surface structure at home and abroad. Because the Yuehai Basin has obvious symbiotic relationship with most of the linear structures on the lunar surface, it is of great significance to understand the evolution of the moon by analyzing its basalt eruption history and tectonics. The main contents and results of this thesis are as follows: 1) the linear structures of the lunar table are classified and interpreted by using the multi-source remote sensing data at home and abroad and combined with the relevant literature. The linear structures of the lunar surface are divided into 10 types and the causes of each kind of formation are analyzed synthetically. By using the DEM data of LRO to focus on the Yueling section and structural analysis, it is considered that the main body of Yueling is the compressional structure formation mechanism of thrust fault superimposed traction fold. (2) as to the dynamic origin of the Yueling structure, most predecessors used the subsidence of the Yuehai basin to superimpose the thermal energy contraction of the moon to explain the origin of the lunar ridge, but it could not explain the preferred position of the central lunar ridge in the near north-south direction of the basin. This phenomenon may be affected by the regional compressive stress in the near east-west direction, which is consistent with the stress state of tidal forces on the low and middle latitudes of the moon, and it is assumed that tidal forces may be the main cause of its formation. Using the Chang 'e-1 CCD image data and the data of moon Orbiter and LRO, 1464 lunar ridges have been identified in positive and middle latitudes of the moon. The results of direction statistics show that, The overall strike of Yueling is similar to the tectonic pattern predicted by Melosh under tidal forces. Therefore, it is inferred that the distribution of the lunar ridge is strongly related to the tidal forces, and further proves that the formation of the lunar ridge is related to tidal forces. Taking Chenghai and Jinghai two connected basins as the study area, the topographic characteristics of the two lunar seas are obtained by processing the DEM data of LRO. The percentage content and maturity distribution of Ti02 Feo were extracted based on clementine multispectral data processing. Based on the data of Chang'e 1 CCD image and the interpretation of LRO and Lo panchromatic images, 126 lunar ridges and 114 moon streams in the study area were extracted. The gravity distribution map extracted by clementine 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.
