The paper describes an attempt to combine anionic exchange enrichment techniques with a spectrochemical method of analysis for the purpose of determining several rare elements in silicate rocks, soils and meteorites. The investigation has for the most part been confined to several elements which form chloro-complexes in hydrochloric acid; notably Ag, Pb, Sn, Bi, Cd, Zn, Tl, Mo and In. These may be absorbed on a basic anion exchanger: after elution and evaporation, the residues are analysed quantitatively by a d.c. arc method. The ability to determine several trace elements in a single general operation is an advantage of the procedure. The combined procedure has been applied to the determination of Cd, Zn, Bi, Tl and Sn in a suite of nineteen rocks including granite G-l and diabase W-l, and specimens of gneiss and sea-mud from the Antarctic.
