| Abstract: | A reconnaissance investigation has been made of the possible combined use of ion-exchange enrichment (cation and anion) and spectrochemical analysis for the determination of several rare elements, notably Ag, Be, Bi, Cd, Cs, In, La, Mo, Nb, Sn, Pb, Tl, Y and Zn, in silicate rocks and allied materials. Observations which have been carried out on granite G-1, a specimen of Cape granite, and diabase W-1, indicate that many of these elements should be easily detected in a wide variety of rocks and soils. The scope of the combined procedure seems to be immense and it is evidently possible to determine several elements in a single operation; the combined procedure should be particularly useful for investigating the general geochemistry of Bi. |
