Distribution of minor and trace elements among Italian chondritic meteorites

Abstract

The cobalt, nickel, zinc, selenium, rubidium and cesium content was determined in eight Italian chondritic meteorites by destructive neutron activation analysis. The chemical procedure involves only a few steps: sample dissolution, radiochemical separation of the elements on inorganic adsorbers (copper grains and zinc ferrocyanide)andonDowex 2x8 anionic resin. Element contents are reported and discussed. Precision and accuracy of the analytical method are given as well. Results and average class values are compared with existing values in the literature. Possible correlations between pairs of elements (Co - Ni, Zn - Se and Rb - Cs) in the examined chondrites, were investigated and discussed
