Figure 3: Visible-NIR spectral properties and mineral chemistry of Chang'e-3 soils from VNIS.
From: Correlated compositional and mineralogical investigations at the Chang′e-3 landing site
(a) Combined VNIS spectra (450–2,400 nm) from sites 0005, 0006, 0007 and 0008. The inset image is from site CE3-0006 of the VNIS (450–950 nm) image mode at 750 nm. The dashed circle indicates the region measured by the VNIS-point spectral mode (900–2,400 nm). (b) VNIS spectra after continuum removal. (c) Pyroxene VNIS peak positions of the CE-3 soils overlain on experimental results from Adams27 and Cloutis and Gaffey28. (d) Fo values of olivine in four CE-3 soils derived from VNIS spectra, overlain on calibration lines (Sunshine and Pieters20).
