Spectral reflectance properties of carbonaceous chondrites: 8. “Other” carbonaceous chondrites: CH, ungrouped, polymict, xenolithic inclusions, and R chondrites

► Reflectance spectra (0.3-2.5 μm) of a number of ungrouped, CH, and R chondrites and unique meteorites were examined. ► Analysis focused on resolvable and diagnostic absorption bands. ► These spectral properties could be related to independently-determined mineralogy. ► Spectral analysis allowed meteorites to plausibly be assigned or excluded from established carbonaceous chondrite groups.
