【摘要】：第谷撞击坑,位于月球南半球的正面,中心位置经纬度为S43°23′40.78″,W11°10′01.02″,具有醒目壮观的辐射纹地貌特征。文中应用多源数据对12个哥白尼纪典型月坑进行统计分析、影像特征的详细解释和对比研究,提出将哥白尼纪划分为早哥白尼世(C1)、中哥白尼世(C2)及晚哥白尼世(C3),并对第谷月坑进行综合数字地质填图,编制了第谷月坑区域地质图和岩石类型分布图。第谷月坑在撞击时由于大量能量的释放或后期火山岩浆活动形成了各种地质地貌,可分为大型地质地貌与小型地质地貌。大型地貌包括辐射纹堆积、坑缘堆积、弧形断块堆积、坑底中心平原堆积与陨石残体中央峰堆积等所形成的地质地貌类型;小型地貌包括堆积、侵蚀和岩浆作用形成的各种地质地貌类型。
[Abstract]:The valley impact crater, located on the front of the southern hemisphere of the moon, is located at the center of S 43 掳23N 40.78 "and W 11 掳10 / 10 01.02". In this paper, 12 typical lunar craters of Copernican were statistically analyzed by using multi-source data. The detailed interpretation and comparative study of the image features showed that Copernican was divided into early Copernican (C1). The Copernican (C2) and the late Copernican (C3) were used to make a comprehensive digital geological map of the Valley Moon Pit, and the regional geological map and the distribution map of the rock types of the Valley Moon Pit were compiled. Due to the release of a large amount of energy or the late volcanic magmatic activity, the Kuyue crater formed various geological landforms during the impact, which can be divided into large geological landforms and small geological landforms. The large-scale landforms include radiative grain accumulation, crater margin accumulation, arc fault block accumulation, bottom central plain accumulation and meteorite central peak accumulation. Small landforms include various geological and geomorphological types of accumulation, erosion, and magmatism.
