【摘要】：月嶺是月球表面上最常見(jiàn)的線性構(gòu)造之一,大多分布于被玄武巖充填的月海之中。雖對(duì)于月嶺成因的觀點(diǎn)不一,但多數(shù)月嶺具有明顯的擠壓變形特征,其展布形式有單列、組或群(常見(jiàn))、網(wǎng)狀或雁列狀等。月嶺的形成和展布既受到月海盆地構(gòu)造的控制,又受到區(qū)域應(yīng)力狀態(tài)的影響。文中以雨海為研究區(qū)域,利用美國(guó)環(huán)月球巡邏者(LRO)的寬視角影像(WAC)數(shù)據(jù)和激光高度計(jì)(LOLA)數(shù)據(jù)對(duì)雨海地區(qū)的月嶺構(gòu)造進(jìn)行解譯和提取,對(duì)月嶺進(jìn)行分類和統(tǒng)計(jì)分析,結(jié)合雨海盆地構(gòu)造特征以及月嶺構(gòu)造的樣式解析,并運(yùn)用沙箱構(gòu)造物理模擬方法對(duì)月嶺的形成和分布進(jìn)行模擬實(shí)驗(yàn),討論了雨海地區(qū)影響月嶺形成和分布的主控因素。結(jié)果表明,月嶺是擠壓體制下形成的;盆地構(gòu)造是控制月嶺類型Ⅰ分布的主要因素;月嶺類型Ⅱ的分布主要受區(qū)域構(gòu)造應(yīng)力控制,其走向主要反映區(qū)域構(gòu)造的最大主應(yīng)力方向。綜上推斷,雨海地區(qū)月嶺形成于近東西向最大主應(yīng)力并受到雨海盆地構(gòu)造的控制,表現(xiàn)為月嶺類型Ⅰ和月嶺類型Ⅱ的綜合樣式。
[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，
