Writeup from MB 104:

Lindong        45°30.49’N, 119°3.47’E

Nei Mongol, China

Find: 2012 Oct

Classification: Ordinary chondrite (LL5-6)

History: The meteorite was found by Y. Wang in Oct. 2012 on the west side of a hill when he was herding sheep. The rock was not taken home until the next year, when he realized it was a meteorite while watching a TV program about meteorites.

Physical characteristics: The meteorite was a single piece with most of the surface covered by black fusion crust. It was later broken into one large fragment and tens of small ones. Dark gray clasts up to 6 cm in length are obvious on the exposed surface.

Petrography: (S. Hu and Y. Lin, IGGCAS) The meteorite shows a brecciated texture, consisting of various lithic clasts in porous fine-grained matrix. The loosely packed, fine-grained matrix consists mainly of olivine, pyroxene and plagioclase, with less abundant troilite and Fe-Ni metal, similar to L or LL chondrites. The clasts include coarse-grained lithic fragments, whole chondrules with sharp boundaries, and fragments of various types of chondrules. The lithic fragments have the similar modal composition of the fine-grained matrix. Three large plagioclase fragments (~200 μm) were also found in the section.

Geochemistry: Mineral compositions and geochemistry: (S. Hu and Y. Lin, IGGCAS) The matrix and lithic breccias have homogeneous chemical compositions. Olivine: Fa28.1±0.3, orthopyroxene: Fs21.3±0.4Wo1.8±0.6, clinopyroxene:Fs10.7±1.2Wo40.2±3.4, plagioclase: An10.1±0.7Ab85.8±0.9, Co content in kamacite: 2.3 wt%. The three plagioclase fragments share similar chemical compositions (An8.7±0.2Ab87.0±0.4) with those in the matrix.

Classification: (S. Hu and Y. Lin, IGGCAS) LL5-6 breccia, but it is possible that clasts of petrologic type lower than 5 are present.

Specimens: The main mass was hold by WangZ.
