ПЕНТЛАНДИТ ИЗ ОБЫКНОВЕННЫХ ХОНДРИТОВ УРАЛА

Some new data on the chemical composition and morphology of the pentlandite from meteorites Ural (H5-6), Kunashak (L5-6), Ozernoye (L5), Severny Kolchim (H3), Kargapole (H4), and Chelyabinsk (LL5) are resulted in the paper. We found a natural decrease in the Ni/Fe ratio in pentlandite from ordinary chondrites by the chondrite series H-L-LL and by direction from 3-d to 5-6-th petrological types within these groups. It is shown that the ratio of Cu/Ni pentlandite of the studied H chondrites is different from pentlandite of L and LL chondrites.
