Abstract
The systematization of data obtained by neutron activation analysis an d radiochemical phase analysis on the content of selenium and silver i n various fragments, fractions, and mineral phases of the Krymka chond rite is performed. There is no correlation between selenium and silver distributions. Evidence is obtained on the isomorphous incorporation of selenium into troilite and, probably, pyrite. Silver is associated with a very small unidentified carrier phase.
