Achondrite (ureilite)

History: A stone of 24.7 g was found within a moraine during the 19th Chinese Antarctic Research Exploration in Grove Mountains.

Physical Characteristics: (Miao B., Xu L., Lin Y., IGGCAS) It is brownish grey, with some yellow and dark grey spots and no fusion crust.

Petrography: It shows typical ureilite texture consisting mainly of olivine and pigeonite with minor carbonaceous matrix (graphite and diamond were identified by Raman). Triple junctions with an angle of 120° are common among coarse-grained silicates.

Geochemistry: Olivine (Fo84.0±0.4 with homogeneous cores), pigeonite (En77.1±0.4Wo9.3±0.1Fs13.6±0.4). Olivine grains have reduced rims (Fa≤5.4 mol%) that contain abundant fine-grained inclusions of Ni-poor metal and sulfide. Limonite veins are common.

Classification: Achondrite (ureilite); moderate shock, extensive weathering.

Specimens: The entire specimen is on deposit at the GUT.
