【摘要】：本论文以月球北极地区为研究区,使用我国探月工程获得的“嫦娥一号”(CE-1)CCD影像数据、干涉成像光谱仪(IIM)数据、激光高度计(LAM)数据与“嫦娥二号”(CE-2)CCD影像数据以及其他已有的月球地质资料,重新厘定了月球地质年代划分方案,并通过对月表物质成分信息、构造要素信息以及地质年代信息的研究,基于Arc GIS平台与Geodatabase数据模型,编制了月球北极地区1:250万地质图(YQ-1),并建立了地质图空间数据库。本论文的主要研究成果与创新点如下:(1)通过对前人对月球地质年代划分方案的总结与研究,对月球地质年代划分方案进行了完善:首先使用统计学方法估算撞击坑年龄尝试性的提出将哥白尼纪进行三分,由老到新划分为早哥白尼世(C1)、中哥白尼世(C2)和晚哥白尼世(C3);其次考虑到月球演化的驱动力变化过程,提出以南极艾肯盆地为标准剖面,将月球前酒海纪划分为艾肯纪与前艾肯纪,但艾肯纪的建立还需确立一个准确可靠的基本岩石-地层单元才能正式建立。本论文对月球地质年代划分方案的完善,初步建立了更加合理的“三宙六纪”的划分方案,为开展月球地质编图与综合研究提供了方便。(2)在月面地质年代划分新方案的基础上,本论文制定了月球地质编图的方案、流程与标准,并基于Arc GIS平台建立了月球地质图符号库、设计了图示图例、建立了地质图模板与空间信息数据库,为全月地质图编制、综合集成研究以及未来其他天体地质编图工作的开展奠定了坚实的基础。(3)通过对月球北极地区物质成分与构造要素的解译分析,认为北极地区以古老的亚铁斜长岩为主,零星发育富镁结晶岩套,靠近月球正面一侧分布少量KREEP岩与低钛、极低钛月海玄武岩,且具有从艾肯纪到年轻的哥白尼纪的多期地质事件,包括大型盆地、撞击坑与玄武岩喷发等事件,此外还分布各种月表线性、环形构造及深部构造,这些都代表了月球丰富的地质演化历史。(4)本论文通过对月球地质图编制的总结与大量月球资料的综合集成研究,将月球构造演化由老至新大致划分为3个主要演化阶段,即:①“岩浆洋”形成、岩浆分异作用和斜长岩壳形成阶段;②月坑大量形成和月海玄武岩充填阶段;③月尘、月壤形成阶段。
[Abstract]:This paper, taking the lunar Arctic as the research area, uses the "Chang'e I" (CE-1) CCD image data obtained by the lunar exploration project, the interferometric imaging spectrometer (IIM) data, the laser altimeter (LAM) data and the "Chang'e two" (CE-2) CCD image data as well as other existing lunar geological data, redefines the lunar geological chronology division. On the basis of the material information of the monthly table, the information of structural elements and the study of geological age information, based on the Arc GIS platform and the Geodatabase data model, the 1:250 million geological map (YQ-1) of the lunar Arctic region (YQ-1) is compiled and the geological map spatial database is set up. The main research results and innovation points of this paper are as follows: (1) through the predecessors The summary and study of the lunar geochronology division scheme have been perfected to the lunar geochronology division scheme. First, the statistical method was used to estimate the age of the impact crater by three points, from old to early Copernicus (C1), middle Copernicus (C2) and late Copernicus (C3); secondly, the lunar performance was considered. In the process of changing the driving force, the standard section of the Antarctic AI en basin was taken as the standard section, and the pre moon wine sea period was divided into the erinogene and the former Erkang period, but the establishment of an accurate and reliable basic rock formation unit was also needed to establish an accurate and reliable basic rock formation unit. The reasonable division scheme of "three Zeus six period" provides the convenience for developing the geological mapping and comprehensive study of the moon. (2) on the basis of the new plan for the division of lunar geological age, the plan, process and standard of the geological mapping of the moon are formulated in this paper, and the lunar geological map symbol base is set up based on the Arc GIS platform, and the illustrations are designed and established. The geological map template and the spatial information database have laid a solid foundation for the compilation of the whole month geological map, the comprehensive integration research and the future other astrogeological mapping work. (3) through the interpretation of the material and structural elements of the moon's Arctic region, the northern polar region is dominated by the ancient ferrous plagioclase, with sporadic development. A small amount of KREEP rock and low titanium, extremely low titanium moon sea Xuan Wuyan, and a multiphase geological event from the AI to the young Copernicus period, including large basins, impact craters and Xuan Wuyan eruptions, are distributed on the side of the moon's front side, and all kinds of lunar linear, ring and deep structures are also distributed. The rich geological evolution history of the moon. (4) through a comprehensive study on the compilation of the lunar geological map and a large number of lunar data, the evolution of the lunar tectonic evolution from the old to the new is roughly divided into 3 major evolutionary stages, that is, the formation of "magmatic ocean", the magma differentiation and the formation of the plagioclase crust, and the formation of a large number of moon craters. And moon sea basalt filling stage; 3. Lunar dust and lunar soil formation stage.
