Opis:: New NWA XXX ureilite found in 2006 was investigated by optical microscopy in reflection and in transmission. Olivines, pigeonite, metal veins and dots, and carbon phases have been revealed and their features and distribution studied. Twinning of pigeonite, reduction rims, and poikilitic inclusions of olivine in large pigeonite crystals have been identified and characterized. NWA XXX meteorite belongs to olivine-pigeonite ureilites.

Opis:: NWA 4967 carbonaceous chondrite thin section was investigated by optical microscopes in transmission and in reflection. Minerals of the meteorite have been identified and microstructure analyzed. Chondrules, matrix, metal phases, AOAs and CAIs are constituents of the rock, as expected. Olivine, clinopyroxene, orthopyroxene, troilite, kamacite and feldspar have been detected. Various types of chondrules including: PO, POP, PP, RP, BO, C, GOP and GO chondrules were identified. Compositional zoning of some olivines, diagnostic cracks in pyroxenes, clinopyroxene twins, and chondrule rims have been observed and analyzed. Our previous EPMA and Raman data as well as present optical data confirm that NWA 4967 belongs to CO3.2 chondrites, as previously classified.
