【摘要】：按照大碰撞假說,月球形成于一次大碰撞事件,拋射出的高能量物質(zhì)留在繞地軌道上,最后吸積形成月球。月球核幔在早期迅速發(fā)生分離,并出現(xiàn)全球性的巖漿熔融,形成了巖漿圈層(巖漿洋)。巖漿洋的結(jié)晶分異和固化導(dǎo)致了月殼的形成。隨著月殼與月幔發(fā)生持續(xù)分異,形成了固化的月殼。而在月球后期的演化歷史中,撞擊作用是最重要的地質(zhì)作用,形成了多尺度、多期次的撞擊盆地和撞擊坑,而大型撞擊盆地多形成于月球演化的早期。月球地質(zhì)圖是開展月球形成與演化研究的重要手段,從20世紀(jì)60年代起,到70年代末止,通過對(duì)阿波羅時(shí)代探月成果的系統(tǒng)總結(jié),完成了第一輪月球地質(zhì)圖的研制。但盡管從20世紀(jì)90年代以來國際月球探測和月球科學(xué)的研究進(jìn)入一個(gè)新的高潮,獲得了大量有關(guān)月球形成和演化的新認(rèn)識(shí),但還沒有正式的新的月球地質(zhì)圖發(fā)布,因此開展新一輪月球地質(zhì)圖的編研,系統(tǒng)總結(jié)后阿波羅時(shí)代的月球探測與研究成果,是非常必要和迫切的。在新一輪月球地質(zhì)圖的編制過程中,需重點(diǎn)關(guān)注圖件比例尺的選擇、月面歷史的劃分以及月球構(gòu)造和巖石建造的表達(dá)。
[Abstract]:According to the large collision hypothesis, the moon was formed in a large collision event, the ejected high-energy material remained in orbit around the earth, and finally accretion formed the moon. The lunar core and mantle separated rapidly in the early stage, and the global melting of magma formed magma circle (magmatic ocean). The crystallization and solidification of magmatic ocean resulted in the formation of lunar crust. With the continuous differentiation between the lunar shell and the moon mantle, the solidified lunar shell is formed. In the late lunar evolution history, collision is the most important geological process, forming multi-scale and multi-stage impact basins and craters, while large impact basins are mostly formed in the early stage of lunar evolution. The lunar geological map is an important means to study the formation and evolution of the moon. From the 1960s to the end of 1970s, the first lunar geological map was developed through the systematic summary of the lunar exploration results in the Apollo era. However, although the international research on lunar exploration and lunar science has entered a new high tide since the 1990s, and a great deal of new knowledge about the formation and evolution of the moon has been obtained, no official new lunar geological map has been published. Therefore, it is necessary and urgent to compile and study a new round of lunar geological maps and systematically summarize the results of lunar exploration and research in the post-Apollo era. In the process of compiling a new round of lunar geological map, we should pay attention to the selection of map scale, the division of lunar surface history and the expression of lunar structure and rock formation.
