After a brief introduction into classification of meteorites, I’ll outline mineralogical, chemical and some isotopic
characteristics of primitive nebular components and compare them with results of condensation models in order to
constrain physicochemical conditions in the early solar nebula. I’ll focus mainly on refractory, Ca,Al,Mg-rich
inclusions and Fe-Ni metal grains. At the end, I’ll briefly speculate on the origin of enstatite chondrites as
possible precursors of the Earth-Moon system and comment on whether the Cu-Al-rich alloys containing quasicrystals
are extraterrestrial.
