Open full text 1 citations

Abstract

Elemental composition, mineral composition and microstructure of NWA 4435 meteorite found in 2006 has been studied by analytical electron microscopy and optical microscopy. It was established that the main meteorite minerals: olivines, pyroxenes, troilite, and graphite identified in the sample represent extraterrestrial minerals typical of carbonaceous chondrites. Chemical and mineral composition, petrologic type of chondrules, their abundance and sizes, the presence of troilite, and abundance of oxidized iron phases confirm CV3 class of this chondrite.
