Gyarub Zangbo        33.126°N, 87.079°E

Xizang, China

Find: 2020 Oct

Classification: Pallasite

History: In October 2020 exploration by Mr. G. Tulga on the Qinghai-Tibet Plateau in the Qiangtang uninhabited area NE of Gyarub Zangbo resulted in the discovery of many disaggregated fragments composed of olivine+metal at 33.126°N, 87.079°E, as well as a much larger single metal-rich specimen nearby at 33.127°N, 87.080°E. All of this material was purchased by Ziyao Wang in October and November, 2020.

Physical characteristics: The material is composed of dark brown olivine and metal in variable proportions from specimen to specimen.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Coarse grained aggregate (mean grainsize ~5 mm) with simple mineralogy of olivine and metal (both kamacite and taenite).

Geochemistry: Olivine (Fa21.6-22.8, FeO/MnO = 61-72, N = 4).

Classification: Pallasite.

Specimens: 120 g including two polished endcuts at UWB; remainder with Mr. Z. Wang.
