| Contents of cosmochemically volatile trace elements (VTE) such as Bi, Cd, Cs, In, and Tl, provide information about the thermal history of the parent planets from which they are derived. However, the cosmochemical affinity of the VTE in chondritic meteorites is uncertain. Fundamentally, complete measurement of concentrations of major, minor, and trace elements in separated minerals should provide this information. We are initiating a study of the distribution of VTE in chondritic meteorites in which ICPMS is used for determination of elements in solutions generated by stepwise dissolution. Our initial experiments focus on the use of ICPMS for major and minor mineral constituent elements. These experiments have resulted in a valid method for determination of these elements in homogeneously dissolved samples. These results and further work on the determination of VTE in homogeneously and selectively dissolved mineral phases from geological standards and chondritic meteorites will be presented. |
