基于月球研究资料的整理、综合及嫦娥1月图影像的实例解读和解释,本文介绍并总结了月球的构造及演化研究的若干概念、研究思路和新的观点.通过纲要性勾画,描绘月球不同类型和阶段构造演化的基本轮廓,重点论述了四个方面的问题:对月面建造历史和月球演化的历史进行了修正,将月球演化按照其特点三分为冥、古、新月宙/界,并提出建立南海纪/系的主张;以东海Hevelius抛射建造(/东海群)分析为例,主张建立构造.建造综合分析思路;从抛射建造与月面相互作用的角度,提出并阐述了掘积系统的概念、掘积系统内外带之间划分的新标志即蚀积盂及其所组成的捩侵蚀带(TSZ);在月球表面形貌构造区划分析的基础上,通过对月盆、月海的时空分布规律的分析、综合,提出月球晚期大轰击(LHB)所造成的月盆开掘期间,具有"轰击漂移"现象,并推测月球LHB过程中出现准对跖翻转;通过对古老月陆区所保存的线性构造解读和构造形迹的组合关系分析,尝试性地提出在冥月宙月球岩浆洋(LMO)演化晚期可能存在单板模式的月全球构造.月球构造演化从初始阶段的LMO所驱动的内动力体制转向冲击造成的外动力体制.

Based on review of previous lunar exploration data, a case analysis and interpretation of the photographic images achieved by Chang'e 1 orbiter, this paper introduces new concepts and summarizes the recent progresses in deciphering lunar tectonics and evolution. We describe different types of lunar structure and outline the lunar tectonic evolution in the following four aspects: ( 1 ) Modification of lunar time scale by dividing lunar evolutional history into three stages of the Eo-, Paleo- and Neolunaris and introducing the Australian and Pre-Australian Periods; (2) New concepts for ejecta formation analysis, by introducing and depicting the excavi-sedimentation system (ESS), the sculpturing-and-infilling spittoon (SIS) and its resulted tearing-sculpture zone (TSZ) based on the case analysis of the Hevelius formation ejected from the Mare Orientale with a new viewpoint of interaction between the ejecta and the pre-existing lunar surface. (3) Possible spatial-temporal shifting of the basin-forming events during the late heavy bombardment (LHB) and a tentative model of sub-antipodal re-orientation of the Moon as the result of LHB by tracking the spatial variation of the lunar topography and temporal migration of lunar basins and maria. (4) Proposal of one-plate global tectonics possibly existed in the Eolunaris at the late stage of the lunar magma ocean (LMO) according to analysis of lunar linear structural grains and the combined planar geometric architecture preserved in the ancient lunar terra. It is concluded that the tenets of lunar tectonic evolution are mono-tendency, characteristic of transformation from endogenic tectonics driven by LMO convection in the initial and early stages to exogenic structures produced by asteroid cratering.
