【Abstract】 This paper deals with the chemical analyses of Boxian chondrite, Anhui. Using different methods, the concentrations of iron in metal phases and troilite. are determined. According to analytical results, all of the chemical parameters of chondrite are calculated, and mainly as follows: Fe/SiO2= 0.50, SiO2/MgO = 1.57, Fe/Fe = 0.21. Together with the F value of 27-29% in olivene, the Boxian chondrite should belong to LL group.更多还原
