摘要： 庐江陨石是一块落的球粒石陨石，本文详细介绍了庐江的化学全分析，铁物相，镍物相和微量元素分析方法，给出了庐江陨石的主要元素组成和微量元素组成特征。由此可以确定该陨石的化学群属于ＬＬ群。

Abstract: Lujiang meteorite is a stony meteorite fallen in Lujiang County, Anhui Province. The major element compositions and the phase compositions of iron and nickle in the meteorite were analyzed by wet chemical methods，and the trace element compositions(including REE)were analysed by ICP-MS. According to the analytical results, some important chemical parameters of the meteorite have been obtained as follows: Al/Si=5.5％，Ca/Si=5.96％，(Fe-Ni)metal= 30.1 mg/g，Fetotal=213mg/g， Nitotal= 12.5mg/g，FeO/F= 0.66，FeO/(FeO+MgO)=28.75％，Fetotal/Si=6.32％，Fetotal/Si=58％. Consequently the meteorite should belong to LL group.
