Presolar grains of hibonite, corundum and probable Ag-containing metal in a primitive material of the Krymka unequilibrated chondrite were found in situ. A native silver and new kinds of a primitive material were originally identified in the chondrite. Most likely, one of the kinds of material belongs to a H-chondrite precursor. It is suggested, that the Krymka parent body was accreted for longer distances from the Sun in comparison with the rest of meteorites, within a region of the protoplanetary nebula which was enriched in mineral condensates. The new Ukrainian meteorite Gruz'ke was classified. The studied unusual metamorphic features of the meteorite indicate to multiple shocks of the chondritic parent body in the asteroid belt. Study of undifferentiated and differentiated meteorites testifies to similarity of their secondary mineralogical characteristics formed in result of complicated shock metamorphism of their parent bodies in the asteroid belt, and terrestrial weathering of the meteorites.
