【摘要】：本論文以月球北極地區(qū)為研究區(qū),使用我國探月工程獲得的“嫦娥一號(hào)”(CE-1)CCD影像數(shù)據(jù)、干涉成像光譜儀(IIM)數(shù)據(jù)、激光高度計(jì)(LAM)數(shù)據(jù)與“嫦娥二號(hào)”(CE-2)CCD影像數(shù)據(jù)以及其他已有的月球地質(zhì)資料,重新厘定了月球地質(zhì)年代劃分方案,并通過對(duì)月表物質(zhì)成分信息、構(gòu)造要素信息以及地質(zhì)年代信息的研究,基于Arc GIS平臺(tái)與Geodatabase數(shù)據(jù)模型,編制了月球北極地區(qū)1:250萬地質(zhì)圖(YQ-1),并建立了地質(zhì)圖空間數(shù)據(jù)庫。本論文的主要研究成果與創(chuàng)新點(diǎn)如下:(1)通過對(duì)前人對(duì)月球地質(zhì)年代劃分方案的總結(jié)與研究,對(duì)月球地質(zhì)年代劃分方案進(jìn)行了完善:首先使用統(tǒng)計(jì)學(xué)方法估算撞擊坑年齡嘗試性的提出將哥白尼紀(jì)進(jìn)行三分,由老到新劃分為早哥白尼世(C1)、中哥白尼世(C2)和晚哥白尼世(C3);其次考慮到月球演化的驅(qū)動(dòng)力變化過程,提出以南極艾肯盆地為標(biāo)準(zhǔn)剖面,將月球前酒海紀(jì)劃分為艾肯紀(jì)與前艾肯紀(jì),但艾肯紀(jì)的建立還需確立一個(gè)準(zhǔn)確可靠的基本巖石-地層單元才能正式建立。本論文對(duì)月球地質(zhì)年代劃分方案的完善,初步建立了更加合理的“三宙六紀(jì)”的劃分方案,為開展月球地質(zhì)編圖與綜合研究提供了方便。(2)在月面地質(zhì)年代劃分新方案的基礎(chǔ)上,本論文制定了月球地質(zhì)編圖的方案、流程與標(biāo)準(zhǔn),并基于Arc GIS平臺(tái)建立了月球地質(zhì)圖符號(hào)庫、設(shè)計(jì)了圖示圖例、建立了地質(zhì)圖模板與空間信息數(shù)據(jù)庫,為全月地質(zhì)圖編制、綜合集成研究以及未來其他天體地質(zhì)編圖工作的開展奠定了堅(jiān)實(shí)的基礎(chǔ)。(3)通過對(duì)月球北極地區(qū)物質(zhì)成分與構(gòu)造要素的解譯分析,認(rèn)為北極地區(qū)以古老的亞鐵斜長巖為主,零星發(fā)育富鎂結(jié)晶巖套,靠近月球正面一側(cè)分布少量KREEP巖與低鈦、極低鈦月海玄武巖,且具有從艾肯紀(jì)到年輕的哥白尼紀(jì)的多期地質(zhì)事件,包括大型盆地、撞擊坑與玄武巖噴發(fā)等事件,此外還分布各種月表線性、環(huán)形構(gòu)造及深部構(gòu)造,這些都代表了月球豐富的地質(zhì)演化歷史。(4)本論文通過對(duì)月球地質(zhì)圖編制的總結(jié)與大量月球資料的綜合集成研究,將月球構(gòu)造演化由老至新大致劃分為3個(gè)主要演化階段,即:①“巖漿洋”形成、巖漿分異作用和斜長巖殼形成階段;②月坑大量形成和月海玄武巖充填階段;③月塵、月壤形成階段。
[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.
