Extended Data Fig. 1

The red and blue lines represent CE4_0015 and CE4_0016. a, Comparison of CE4_0015 and CE4_0016 with mare soil (particle size <45 μm) samples: 10084, 12001, 12030, 15041, 15071, 70181, 71501, 79221. The 1-μm and 2-μm absorption bands of CE4_0015 and the 2-μm absorption band of CE4_0016 (dashed lines) obviously shifts to shorter wavelengths and differ considerably from the spectral features of the mare samples. b, Comparison of CE4_0015 and CE4_0016 with highland samples (particle size <45 μm): 14141, 14163, 14259, 14260, 61141, 61221, 62231, 64801, 67461, 67481. The 1-μm and 2-μm absorption bands of CE4_0015 and the 2-μm absorption band (dashed lines) of CE4_0016 resemble those of the highland samples. However, the 1-μm absorption band of CE4_0016 is more similar to that of basaltic soil, which can be attributed to elevated abundance of olivine (see main text).
