摘　　要：Iron meteorites from Nandan, Guangxi ; Wushike, Xinjiang; Shangdu, Hebei and Huangling, Hubei are investigated with a spark souree mass speetrometer for their Cr, Ni, Co, Cu, Zn, Ga, Ge, As, Mo, Ru, Rh, Pd, Os and Ir contents. The accuracy of the results and the factors affecting it are discussed. It is preliminarily concluded,while textural evidences of these meteorites are also taken into account, that the Nandan, Wushike and Shangdu meteorites belong to IA, Ⅲ .4 and ⅢE groups respectively. The Ni, Ga and Ge contents in the Huangling iron meteorite come close to that of mesosiderites.Iron meteorites from Nandan, Guangxi; Wushike, Xinjiang; Shangdu, Hebei and Huangling, Hubei are investigated with a spark source mass spectrometer for their Cr, Ni, Co, Cu, Zn, Ga, Ge, As, Mo, Eu, Rh, Pd, Os and Ir contents. The accuracy of the results and the factors affecting it are discussed. It is preliminarily concluded, while textural evidences of these meteorites are also taken into account, that the Nandan, Wushike and Shangdu meteorites belong to IA, III A and IILE groups respectively. The Ni, Ga and Ge contents in the Huangling iron meteorite come close to that of mesosiderites.
