Writeup from MB 109:

Loulan Yizhi 046        40°24’16.59"N, 89°54’51.01"E

Xinjiang, China

Find: 2019 Jun 28

Classification: Ordinary chondrite (L5, melt breccia)

Petrography: The rock is a breccia and mainly composed of olivine, low-Ca pyroxene, secondary plagioclase, Fe-Ni metal, and troilite. Chondrules are present in the clasts, with poorly defined rims. The clasts are surrounded by lighter-colored quenched melt and igneous-textured microporphyritic melt domains. The size of plagioclase in clasts is mainly from 2 to 50 μm. The pyroxene phenocrysts in the melt domains show heterogeneous compositional zoning. Most of the metal are surrounded by coatings of troilite. Troilite is single crystal or polycrystalline.

Geochemistry: Olivine Fa24.3-26.0, N=6; Low-Ca pyroxene Fs20.4-20.5Wo1.47-1.91, N=5 (EPMA)
