Several chondrules show brownish staining due to terrestrial alteration. Opaque phases are metal often occurring as blebs in chondrules, sulfides and their respective alteration products. Geochemistry: Ni in sulfides <0.55 wt%, N=11 Classification: Carbonaceous chondrite (CVred3). Reduced subgroup based on low concentrations of Ni in sulfides. | ||||||||||||||||||||||||||||||
