【摘要】：利用NASA行星数据系统提供Apollo计划登月点采样线路影像数据,通过与嫦娥二号CCD数据、印度M~3数据空间校正获得采样路线坐标。开展嫦娥二号CCD数据与印度M~3数据MAP(后验概率)融合并选择Apollo 15、Apollo 16-62231的LSCC测得的标准岩石双向反射率光谱与M~3、嫦娥二号进行交叉定标。本文采用月球岩石光谱谱型全特征分析方法,选取涵盖Apollo计划登月获取的36个基站主要岩性87种、285件岩石样品,利用校正后的M~3数据分析月球典型岩石各阶吸收反射特征,建立月球典型岩石标准遥感影像光谱库,此后应用Apollo 623个岩石样品进行对比得到很好结果,同时完成Apollo 16登月点周围领域岩性分布图,并讨论了研究区的岩石成因,Apollo 16区域形成于高地大撞击,在早期的研究中已经被用于划分月球年代,本文方法对于月球岩石类别研究与理解月球的岩浆演化具有重要的研究价值。
[Abstract]:The NASA planetary data system is used to provide the sampling line image data of the lunar landing point of the Apollo program. The sampling route coordinates are obtained by spatial correction of the Indian MG3 data with the Chang 'e-2 CCD data. The CCD data of Chang 'e-2 and Mi _ 3 data of India were fused and the standard rock reflectance spectra measured by LSCC of Apollo 15 and Apollo 16-62231 were selected for cross-calibration with Mi _ 3 and Chang'e _ 2. In this paper, the spectral spectrum of lunar rocks is used to analyze the absorption and reflection characteristics of typical lunar rocks in every order by using the corrected data of Mian 3, which includes the main lithology of 87 kinds and 285 rock samples of 36 base stations, which cover the lunar landing on the moon by using the method of full-feature analysis of the spectrum of lunar rocks. The standard remote sensing image spectral database of typical lunar rocks was established, and good results were obtained by using Apollo 623 rock samples, and the lithologic distribution map of the area around the landing point of Apollo 16 was completed at the same time. It is also discussed that the petrogenetic region of the study area, Apollo 16, was formed during the high altitude impact, and has been used in early studies to date the moon. The present method is of great value in studying and understanding the magmatic evolution of the moon.
