【摘要】：线性构造是月球表面除环形构造外另一种重要的构造样式,呈线状延伸。月表线性构造种类繁多,其成因也具有多样性。它能反映全月球或者区域性的构造特征与应力状态,在某种程度上反应月球内部的地质信息,对研究月球的构造演化有重要的意义。文中以静海地区为例,经过对"嫦娥二号"CCD的影像数据及从中提取的DEM数据进行解译,提取出了284条月岭和71条月溪,并对月岭月溪进行分类和统计分析,然后结合静海地区线性构造的分布特征及坡度图、等值线图,分析其演化过程。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。
[Abstract]:Linear structure is an important structural pattern of lunar surface in addition to annular structure, which extends linearly. There are many kinds of linear structures of the lunar surface, and their genesis is also diverse. It can reflect the tectonic characteristics and stress state of the whole moon or region, and to some extent reflect the geological information of the lunar interior, which is of great significance to the study of the tectonic evolution of the moon. Taking Jinghai area as an example, through the interpretation of the image data of Chang'e-2 CCD and the extracted DEM data, we have extracted 284 monthly ridges and 71 monthly streams, and classified and statistically analyzed the Yueling and Yueyue streams, which are divided into four regions: Chang'e-2 (Chang'e-2) and Chang'e-2 (Chang'e-2). Then, the evolution process of the linear structure in Jinghai area is analyzed by combining the distribution characteristics of the linear structure, slope diagram and contour map. The results show that most parts of Yuexi Ridge in Jinghai area are in the area with lower elevation in the west; The formation time of Yuexi in Jinghai Basin is about the same as that of basin formation and basalt filling, and the forming time of Yueling is about the same as that of impact crater. The lunar ridge formation model, which extends from one end to the crater in Jinghai Basin, belongs to the dike model of volcanic genesis model.
