Geochemical exploration requires a large number of samples to be analyzed rapidly, precisely and accurately for a lot of elements. This task has been ful- filled by ICP-AES well. Samples were decomposed with hydrofluoric acid and perchloric acid a nd analyzed on a 60-channel Jarrell-Ash 1160 Plasma Atom- Comp. Analytical results determined on 37 elements in 8 Chinese Geochemical Standard Samples are presented and agree well with usable values. Several International Geochemical Reference Samples have been"analyzed and correlation data are also presented.
