5.3, 8.3, and 30.1 grams. Eucrite
TKW 847 grams. Possibly observed fall 15 January 2021.
From the MetBul:
At about 7:44 am (Beijing time) on Jan. 15, 2021, a fireball was witnessed by local people in Urumqi, Xinjiang province, China. The fireball traveled W to E and was recorded by a CCTV camera. A series of strong detonations were heard by local residents in the Mulei area. Several meteorite hunters immediately conducted a field search in the area where the fall was thought to have occurred, but they failed to find any specimens. In early May 2021, two workers noticed one black stone (190 g) under a solar power panel near a power plant in Tulufan. A picture of the stone was uploaded to the web, and it was identified as a highly possible fall. These two workers then went back and found another black stone (47 g) in the same area. Immediately after, numerous meteorite hunters searched the area intensively, and five more stones (167, 93, 14, 266, and 70 g) with shining fusion crust were found by Mei Hua, Wang Weiwei, Liu Yukun, Zhao Tailu, Zhao Yuxian, Chen Pengli and Wang Zijian.

Qiquanhu is a superb fresh brecciated (fractured) eucrite. The Met Bullin states that there was a fireball, witnessed by local people in Urumqi, Xinjiang provices, China on January 15, 2021.
According to Met Bulletin, the first seven black stones were found by seven different people (two power plant workers and shortly afterwards from five meteorite hunters) in May 2021. The total weight of the first seven Qiquanhu meteorites is 847 g.
By personel communication with Qiang Xu I received the message that the total known weight was risen up to about 10 kgs, all incomplete individuals. The term "all incomplete individuals" can probably be explained by the fact that the material is fragile due to its brecciated, broken structure. I only handle my three collection pieces – if necessary – carefully with clean cotton gloves so as not to cause further breakage.
I received my three great looking, super fresh Qiquanhu collection samples from my dear Chinese collector friends, Yilang Ying and Qiang Xu, in exchange for other Chinese meteorite samples. It was all a very polite, friendly and respectful communication.
The three Qiquanhu samples have glossy fusion crust with flow lines. The end section (5.3 g) and the fragment slice (8.3 g) fit together (source: YY, 07/2022). Those two, as well the almost complete distinctly oriented individual (30.1 g) (source: QX, 12/2022), are among the most beautiful of my eucrite samples and they have a very high ranking number in my achondrite treasure box and display.

Pic 8-10 – close view, 8 x 6 mm, glossy fusion crust, distinct flow lines and overflow lip of the Qiquanhu individual
