Screening and classification of ordinary chondrites by Raman spectroscopy [PDF]
Meteoritics & Planetary Science, 2015 AbstractClassification of ordinary chondrite meteorites generally implies (1) determining the chemical group by the composition in endmembers of olivine and pyroxene, and (2) identifying the petrologic group by microstructural features. The composition of olivine and pyroxene is commonly obtained by microprobe analyses or oil immersion of mineral ...
