【摘要】：近年来获取的月球高分辨率影像数据使月面哥白尼纪的线性构造形迹(如属于挤压构造的叶片状悬崖和属于伸展构造的地堑)成为行星地质学界的研究热点.这些构造单元是指示月球地质演化史和热演化史的重要窗口.本课题组尝试根据月表哥白尼纪线性构造单元的全球分布,全面分析其可能的成因模式,验证其应力来源是否只可能是月球晚期的全球收缩,研究月面区域地质背景对其形成过程的影响.在整理原始数据的过程中,作者注意到月球表面很多非构造成因的线性形迹极易与哥白尼纪的小型伸展和挤压构造相混,造成错误的解译.藉此,本文系统地比较了月球表面哥白尼纪构造形迹与月壤台阶、撞击熔融流、二次撞击坑链和月溪等线状形迹之间的相似性及其区别特征,并提出多尺度分析在研究月球表面哥白尼纪构造形迹中的重要性.
[Abstract]:The lunar high-resolution image data obtained in recent years have made the linear tectonic traces of the lunar Copernican period (such as the foliar cliffs belonging to the compressional structure and the extensional graben) a hot spot in the field of planetary geology. These tectonic units are an important window to indicate the history of geological evolution and thermal evolution of the moon. Based on the global distribution of the Copernican linear tectonic units on the lunar surface, our team attempts to analyze its possible genetic model and verify whether the source of the stress is only the global contraction of the late lunar period. The influence of the regional geological background on the formation process of lunar surface is studied. In the course of collating the original data, the authors noticed that many linear traces of non-tectonic origin of the lunar surface are easily mixed with the Copernican small extensional and compressional structures, resulting in erroneous interpretation. In this paper, the similarity and distinguishing characteristics between Copernican tectonic traces on the surface of the moon and lunar soil steps, impingement melting currents, secondary impact crater chains and lunar streams are systematically compared. The importance of multi-scale analysis in the study of Copernican tectonic traces on the lunar surface is also presented.
