抄録

The major mineralogical components of Yamato-791197 determined from reflectance spectra are calcium-rich clinopyroxene, plagioclase, and <30% olivine. These results are determined from visual examination of spectra in 1.0μm region, with continuum removed and using a multiple-order derivative analysis to detect band positions. Geochemical constraints on the provenance of Y-791197 provided by the Apollo orbital X-ray and γ-ray spectrometers indicate that areas with a surface chemistry like that measured in geochemical analysis of Y-791197 are extremely limited on the central nearside. Only 25% of highland craters spectrally measured on the nearside consist of high-calcium pyroxene. Only one crater, Eimmart A, located on the eastern limb close to Mare Crisium, consists of moderately calcium-rich pyroxene, plagioclase and a significant olivine component.
