Qidong is a L/LL5-an chondrite meteorite fallen in 1982 in China. After detonation a single individual specimen was found in the field. Other circumstances of fall and recovery were not reported.[1]
Composition and classification [edit]
This meteorite is intermediate between L and LL ordinary chondrites, possibly indicating formation on a separate parent body.[3] Its fayalite, ferrosilite place this stone at the extreme higher end of L chondrites, the metal content is typical of LL chondrites and the Co abundance in matrix kamacite (15 mg/g) is at the extreme lower end of LL chondrites.
