【摘要】：月岭是月球表面上最常见的线性构造之一,大多分布于被玄武岩充填的月海之中。虽对于月岭成因的观点不一,但多数月岭具有明显的挤压变形特征,其展布形式有单列、组或群(常见)、网状或雁列状等。月岭的形成和展布既受到月海盆地构造的控制,又受到区域应力状态的影响。文中以雨海为研究区域,利用美国环月球巡逻者(LRO)的宽视角影像(WAC)数据和激光高度计(LOLA)数据对雨海地区的月岭构造进行解译和提取,对月岭进行分类和统计分析,结合雨海盆地构造特征以及月岭构造的样式解析,并运用沙箱构造物理模拟方法对月岭的形成和分布进行模拟实验,讨论了雨海地区影响月岭形成和分布的主控因素。结果表明,月岭是挤压体制下形成的;盆地构造是控制月岭类型Ⅰ分布的主要因素;月岭类型Ⅱ的分布主要受区域构造应力控制,其走向主要反映区域构造的最大主应力方向。综上推断,雨海地区月岭形成于近东西向最大主应力并受到雨海盆地构造的控制,表现为月岭类型Ⅰ和月岭类型Ⅱ的综合样式。
[Abstract]:Yueling is one of the most common linear structures on the lunar surface, most of which are distributed in the lunar sea filled with basalt. The formation and distribution of Yueling are not only controlled by the structure of the Yuehai Basin, but also influenced by the regional stress state. Based on the data of WACand LOLAA, the wide view image of Lro, the lunar ridge structure in the rain sea area is interpreted and extracted, and the lunar ridge is classified and statistically analyzed. Combined with the structural characteristics of Yuhai Basin and the style analysis of Yueling structure, the formation and distribution of Yueling are simulated by the physical simulation method of sandbox structure. The main controlling factors affecting the formation and distribution of the lunar ridge in Yuhai area are discussed. The results show that the lunar ridge was formed under the compression system, and the basin structure is the main factor controlling the distribution of the lunar ridge type 鈪，
