【摘要】：月球表面所呈现的构造特征对于理解并进一步重建其地质构造演化具有极其重要的研究意义,其中线性构造是一种极为重要的构造现象,主要分布在月海区域,极少数分布在月陆。线性构造在月球表面的分布状况通常与月球的内动力地质作用有着密切的关系。非常稀少的样品和几乎不可能实现的野外勘察使得遥感技术成为行星科学研究的极为有利的手段。中国、日本、美国、印度等几个国家先后发射的多颗新型的探测月球的卫星获取了许多高质量的遥感影像数据,为我们研究月表构造提供了很大的帮助。本文以月球静海地区为例,利用我们已有影像数据,其中包括CE-1的120m CCD影像数据、500m分辨率激光高度计数据、100m分辨率LROC数据和60m分辨率的LOLA数据,吸取前人将地形曲率的原理应用于地球上线状地物和线性构造提取的经验,尝试将这一原理应用于月表静海地区线性构造的自动提取,取得良好效果。同时,根据月表线性构造的形态建立遥感解译标志,对提取结果进行分类统计,进而分析其成因和演化过程,建立演化模型。静海盆地内部对其演化过程中所造成巨大影响的线性构造主要有月岭、月溪、地堑和垮塌构造。研究结果表明,静海地区的月溪月岭大部分分部在西部高程较低的区域;静海盆地月溪的形成时间与盆地形成及玄武岩的填充时间大致相同,月岭的形成时间大致与撞击坑的形成时间相同;静海盆地中一端延伸至撞击坑的月岭形成模型属于火山成因模型中的堤坝模型;地堑是无弹性的底层上面易破碎的有弹性的地层过度拉伸的结果,其形成的过程中发生了两次同时或不同时的断裂;垮塌构造是在陨石撞击月球表面形成撞击坑的时候在撞击坑的内壁形成的环撞击坑的线性构造,其一般出现在较复杂的大型撞击坑内,并且呈批出现。这一研究将有助于进一步了解静海地区一定时期内的演化过程及构造因素对其形成中的影响,从而加深对月球表面整个演化过程的认识。
[Abstract]:The structural characteristics of the lunar surface are of great significance for understanding and further reconstructing the geological evolution of the lunar surface, among which linear tectonics is an extremely important tectonic phenomenon, which is mainly distributed in the lunar sea area. The distribution of linear structures on the surface of the moon is usually closely related to the lunar internal dynamic geology. Very few samples and almost impossible field surveys make remote sensing technology. To become an extremely advantageous means of planetary science. A number of new lunar exploration satellites launched by Japan, the United States, India and other countries have acquired a lot of high-quality remote sensing image data, which provides a great help for us to study the structure of the lunar surface. In this paper, we take the still sea area of the moon as an example. Using our existing image data, including 120m CCD image data of CE-1 and 500m resolution laser altimeter data, 100m resolution LROC data and 60m resolution LOLA data are used. Based on the previous experience of applying the principle of topographic curvature to the extraction of linear ground objects and linear structures on the earth, this paper attempts to apply this principle to the automatic extraction of linear structures in the area of the monthly surface of the still sea, and obtains good results. According to the shape of the linear structure of the moon table, the remote sensing interpretation marks are established, the extraction results are classified and counted, and the origin and evolution process are analyzed. The linear structures which have great influence on the evolution process of Jinghai basin are mainly Yueling, Yuexi, graben and collapse structure. Most of the Yuexiyue Ridge in Jinghai area is located in the area with lower elevation in the west, the formation time of Yuexi in Jinghai Basin is approximately the same as that of basin formation and basalt filling, and the formation time of Yueling Ridge is approximately the same as that of impact crater. The lunar ridge formation model extending from one end of the Jinghai basin to the crater belongs to the embankment model in the volcanic genesis model, and the graben is the result of excessive stretching of the elastic stratum on the inelastic bottom. Two simultaneous or different faults occurred during its formation; the collapse structure is the linear structure of the ring crater formed on the inner wall of the crater when the meteorite hits the surface of the moon. This study will contribute to the further understanding of the evolution process in the Jinghai area and the influence of tectonic factors on its formation during a certain period of time. So as to deepen the understanding of the whole evolution process of the lunar surface.
