Writeup from MB 101:

Karavannoe 57°46.87’N, 47°40.78’E

Russia

Found: 1960s

Classification: Pallasite (Eagle Station group)

History: One stone was found by Sergei Blednykh and Aleksander Blednykh at Karavannoe village (Tuzhinsky region, Kirovsky district, Russia). The stone was known since the 1960s, but was only recognized as a meteorite 28 Sep 2010.

Physical characteristics: The meteorite is a 30-40 cm brown stone of irregular shape covered in an ~1 cm thick oxide shell.

Petrography: (C. A. Lorenz, Vernad) Meteorite shows coarse-grained greenish-yellow olivine enclosed in Fe,Ni metal matrix. Olivine grains are fractured, the cracks are filled by weathering products. Olivine contains small grains of chromite, pyroxene, and FeNi metal. Accessory minerals are pyroxene, chromite, troilite, phosphates, and schreibersite.

Geochemistry: (N.N. Kononkova, Vernad; S.E. Borisovsky, IGEM): Olivine Fa_19.7(Fe/Mn=96.8 at%); pyroxene Fs_16.8Wo_1.4(Fe/Mn=54.1 at%). Bulk Ni content in Fe,Ni metal, measured by XRF, is 14 wt% (I.A. Roshchina, Vernad). Oxygen isotopic composition of olivine: (I. A. Franchi, OU): δ¹⁷O = -6.25; δ¹⁸O = -2.642, Δ¹⁷O = -4.878 (all per mil).

Classification: Pallasite (Eagle Station grouplet)

Specimens: The type specimens (32.45 kg slab, 0.24 kg piece) and two polished sections are on deposit at Vernad. The finder holds the main mass.
