摘要
Based on a comprehensive analysis of the mineral composition of major lunarrocks (highland anorthosite, lunar mare basalt and KREEP rock), we investigate the reflectancespectral characteristics of the lunar rock-forming minerals, including feldspar, pyroxene andolivine. The affecting factors, the variation of the intensity of solar radiation with wavelengthand the reflectance spectra of the lunar rocks are studied. We also calculate the reflectivity oflunar mare basalt and highland anorthosite at 300 nm, 415 nm, 750 nm, 900 nm, 950 nm and 1000 nm. Itis considered that the difference in composition between lunar mare basalt and highland anorthositeis so large that separate analyses are needed in the study of the reflectivity of lunar surfacematerials in the two regions covered by mare basalt and highland anorthosite, and especially in theregion with high Th contents, which may be the KREEP-distributed region.
