Gruz’ke 48°32’N, 32°03’E Kirovograd, Ukraine Find: 27 March 2007 Classification: Ordinary chondrite (H4) History: The meteorite was collected by Kyiv geophisicists P. Nyemensky, Y.Rozanovich, and O.Pakhovchak during a geophysical field expedition. For more than two years the "strange" stone was preserved in Kirovska expedition (Kyiv) as a probable meteorite. In July 2009 a small part of the sample was polished and a section given to NASU for study. Physical characteristics: The stone is 3423 g, 18.0 × 13.0 × 8.5 cm in size, and fusion crusted. The crust is brown with regmaglypts and with evidences of weathering. Petrography: (V.P. Semenenko, NASU) The chondrite is composed of a dark-colored lithology with a ordinary chondritic texture. The majority of the chondrules have porphyritic or barred olivine structures. The chondrule glass is slightly devitrified. Major phases are olivine and pyroxene. Minor phases are feldspar, kamacite, taenite, troilite and Ca- pyroxene. Rare grains of chromite, native copper, merrilite, Cl-apatite, ilmenite and silica are present. The sample contains evidences of shock metamorphism. The main of them are the structures of plastic deformations, shock heating and melting. The chondrite is slightly weathered. Geochemistry: (V.P. Semenenko, A.L. Girich, N.V. Kychan, S.N. Shirinbekova) olivine Fa17.9-19.3 (av. Fa18.6, N=10), low Ca pyroxene Fs15.9-17.4Wo0.93-1.88, (av. Fs16.5Wo1.35, N=28); Ca-rich pyroxene Fs5.94-6.89Wo45.2-46.4, (av. Fs6.31Wo45.7, N=3); feldspar Ab76.2-84.6 Or4.47-9.64 (av.Ab81.9Or6.01, N=11); chromite (wt.% - 3.74 MgO, 6,73 Al2O3, 2.35 TiO2, 0.63 V2O3), kamacite (wt.% - 6.68-8.32 Ni, 0.27- 0.53 Co), taenite (48.5-54.8Ni, 0.02-0.13Co), goethite (9.82NiO, 0.39S). Classification: H chondrite (H4, S4, W2) Specimens: The main mass 3227 is located in NASU and 134 in the Committee of Meteorites NAS of Ukraine, Kyiv | ||||||||||||||||||||||||||||||||||||||
