Ulyanovsk                           54°21'53.81''N, 48°35'29.21''E

Ulyanovsk, Russia

Find: 24 May 2006

Ordinary chondrite (H5)

History: One stone of the meteorite was found by S. G. Bildzyukevich in the Zavolzhsky District of Ulyanovsk, in a vacant lot near the intersection of Antonov and Ulyanovsky Avenues. A part of the meteorite was sticking out of the ground by ~2 cm and was thus polished by tires of cars going to the nearby repair shop. A sample of the meteorite was given to the meteorite collection of the Russian Academy of Sciences by members of the Russian Society of Meteoritical Admirers, D. A. Kazakov and Dr. A. K. Stanyukovich.

Physical characteristics: One 4680 g sample with a polyhedron shape, 16 × 16 × 12 cm in size. The surface was slightly covered by iron hydroxides.

Petrography: (Lorenz C. A., Ivanova M. A., Vernad.) The meteorite contains olivine, pyroxene, FeNi-metal, sulfides, chromites and abundant (~80%) chondrules and their fragments. The chondrules range in size from 0.2 to 0.7 mm in apparent diameter to 0.3 mm. The chondrule margins are not clear and the meteorite contains a large variation in the textural types of chondrules including BO, PO, POP, and PP.

Geochemistry: (Ivanova M. A., Vernad.) Olivine (Fa17.9) and orthopyroxene (Fs16.1Wo1.2).

Classification: Ordinary chondrite (H5); S3, W2.

Type specimens: A total of 960 g of sample and one thin section are on deposit at Vernad. D. A. Kazakov, A. K. Stanyukovich, and S. P. Vasiliev hold the main mass.

Submitted by: M. Ivanova, Vernad.
