Tabas 001        33°39.12’N, 56°59.77’E

Khorasan, Iran

Find: 15 Jan 2016

Classification: Ordinary chondrite (L5)

History: The meteorite was found in the desert of Iran by Mr. Zacharchuk and Mr. Kryachko in January 15, 2016.

Physical characteristics: The meteorite is broken into 14 pieces. A dark-brownish, partly eroded fusion crust is present.

Petrography: The meteorite has brecciated chondritic texture. The main mass (host) composes of chondrules fragments, mineral grains and minor well formed chondrules of 300-900 µm in diameter of BO, RP, PO, PP, POP, rare of C types, troilite (~3 vol%), minor metal FeNi, iron hydroxides, accessory chromite. The main mass contains of ~15 vol% of the angular rock clasts of 5-15 mm in size. Some of them are composed of brecciated chondritic material, similar to that of the host. The clasts of another type are comprised by recrystallized medium-grained aggregates of pyroxene, feldspar (up to 400 µm in size) and olivine, minor troilite and metal grains.

Geochemistry: Mineral compositions and geochemistry: the host and fine-grained clasts are composed of olivine Fa24.9±0.3 (N=15) and pyroxene Fs20.5±0.1Wo1.5±0.2 (N=15); the medium-grained clasts are composed of Fa20.4±0.2 (N=15) and Fs17.4±0.2Wo2.6±0.8 (N=13).

Classification: Based on the texture and composition, the meteorite is classified as ordinary chondrite breccia composed of L5 host with L5 and H7 clasts (L5 polymict breccia).

Specimens: A type specimen of 962 g total weight and thin section are on deposit at Vernad, the finders hold the main mass.
