The local residents of Tanxi town, Pujiang County, Jinhua City, recovered the first three pieces immediately (1.7 , 0.34, and 0.07 kg). Two palm-sized pits were created on the concrete floor. Ten more pieces (0.48, 0.42, 0.76, 0.69, 0.47, 1.39, 0.55, 0.95, 1.9, and 0.98 kg) were recovered beween16 December and 18 January 2023. The total mass is at least 10.7 kg.

Several 0.4-1-mm-sized chondrule relicts are present. Plagioclase is up to 50 µm in size. Olivine shows sharp optical extinction Geochemistry: olivine (Fa19.2-19.8, Fe/Mn=36-41, n=16), low-Ca pyroxene (Fs1.2-17.4Wo0.9-1.8, Fe/Mn=2-24, n=12), Ca-rich pyroxene (Fs6.7Wo46.0, Fe/Mn=14, n=1), plagioclase (An11.3-12.0Or3.9-6.4) Classification: The texture and mineral composition are consistent with H6 chondrites. | ||||||||||||||||||||||||||||||||||||||
