The abundance of cadmium and zinc in meteorites

A stable isotope dilution technique using solid source mass spectrometry has been used to accurately determine Cd and Zn in a wide range of materials. The abundance of Cd has been determined in 19 iron, 28 stone and 1 stony-iron meteorites, together with a number of other samples. The abundance of Zn has also been determined for most of these samples. This has enabled the relationship between Cd and Zn to be examined in iron and stone meteorites. The abundance pattern of Zn in iron meteorites supports the existence of chemical groups.
