| Abstract: | Copper, iridium, platinum and gold content was determined in 15 italian chondritic meteorites by destructive neutron activation
analysis. The chemical procedure involves few steps: sample dissolution, group separation of noble metals on inorganic adsorbers
and gamma-ray spectrometry. Element content and atomic abundances (Si=106 atoms) are presented and discussed. Precision and accuracy of the analytical method are given as well. Copper, platinum and
gold content is within the reported ranges for ordinary chondrites, whereas the iridium content is located on the low side
of reported values. |
