Fig. 3: Kaguya MI spectral analysis of Dawes crater.
From: Lunar samples record an impact 4.2 billion years ago that may have formed the Serenitatis Basin
a Dawes crater as seen by the Lunar Reconnaissance Orbiter Narrow Angle Camera (low-Sun controlled mosaic). The star denotes the ___location of the three pixels for which modelled spectra closely resemble Multiband Imager spectra and are within the same compositional range as the 78235 and 78236 samples. b The Multiband Imager continuum removed spectra for these three pixels (solid lines) along with their best modelled spectral fit (dashed lines). The spectra have been offset for clarity. Spectra 1 is modelled as 35 wt.% plagioclase, 52 wt.% low-calcium pyroxene, 7 wt.% high-calcium pyroxene and 7 wt.% olivine. Spectra 2 is modelled as 41 wt.% plagioclase, 47 wt.% low-calcium pyroxene, 6 wt.% high-calcium pyroxene and 6 wt.% olivine. Spectra 3 is modelled as 40 wt.% plagioclase, 48 wt.% low-calcium pyroxene, 6 wt.% high-calcium pyroxene and 6 wt.% olivine.
