Abstract In this paper, X-ray fluorescence spectrometry (XRF), no standard complete quantitative analysis and microwave digestion/inductively coupled plasma mass spectrometry (ICP-MS) were used to perform the elemental analysis of two types of meteorites. Determination of macro-element in meteorite samples by XRF method, and determination of micro-element in meteorite samples by ICP-MS method. Experimental results show that: The XRF method can be used to detect the meteorite samples content in 10 μg·g-1 above all metal and nonmetal elements, it is concluded that the 6 major elements in the two types of meteorites are Fe，Mg，Si，Na，Al，Ca. Iron meteorites in different regions contain large amounts of Fe, stone meteorites contain a large amount of Si . Determination of 24 elements in meteorites by ICP-MS, by comparing and analyzing the 9 elements of V，Ni，Mo，Ag，Sn，La，Gd，Hg，Pb, the content of heavy metals and rare earth elements in iron meteorite is much higher than that in stone meteorite. The content of Sn in all iron meteorite samples is about 10~25 times as much as that in stony meteorites, the contents of rare earth elements La and Gd in iron meteorites are about 6 times as much as those of stony meteorites. The content of Pb in 5A and 6A iron meteorites in Xinjiang is 5~13 times more than that in iron meteorites from Shandong (1A, 2A, 3A, 4A). The stone meteorites from Inner Mongolia (9B, 10B) have more than three elements La，Mo and Gd from the stone meteorites (7B, 8B) from Xinjiang.
