Writeup from MB 105:

Xilin        44.111664°N, 115.066212°E

Nei Mongol, China

Find: 2015 Mar

Classification: Ordinary chondrite (H4)

History: One 41 kg stone and 6 small fragments were found by Mr. Miao Gui Jun in March 2015, partially buried in a grassland region of Inner Mongolia. All pieces have fusion crust and the smaller fragments seem to have been broken from the main mass.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed chondrules occur within a relatively coarse grained matrix containing abundant stained kamacite plus accessory sodic plagioclase, merrillite and troilite.

Geochemistry: Olivine (Fa18.7-18.8, N = 3), orthopyroxene (Fs15.5-16.2Wo2.0-1.7, N = 3), clinopyroxene (Fs5.4-6.9Wo46.1-44.2, N = 2).

Classification: Ordinary chondrite (H4).

Specimens: 24.7 g including two polished thin sections at UWB; remaining material with the finder.
