The Xi Ujumqin meteorite fell in Aug. 1980 at Xi Ujumqin County, Nei Monggol, China.This chondrite can be classified as L6 type based on the bulk chemical analysis (6wt% metal iron, 24% total iron, olivine Fa-26) and the textural feature of complete intergrowth of the chondrules with the matrix, The Mianchi meteorite is a type Hs chondrite that fell in Sep, 1980 at Mianchi County,Henan, China. Apart from porphyritic, barred, radial, cryptocrystanine chondrules, many intermediate-type or mixed-type chondrules are observed in the Mianchi meteorite under the microscope. It is suggested that the origin of chondrules showing different textures depend on the primeval compositions and cooling rates, 相似文献
