TRACE-ELEMENT GEOCHEMISTRY - APPLICATIONS TO THE IGNEOUS PETROGENESIS OF TERRESTRIAL ROCKS

Trace element geochemistry, like the entire field of geochemistry, has applications in many earth science problems. In a brief contribution, it is not possible to report on recent advances in all aspects of trace element geochemistry; thus, I focus on applications in determining the origin and evolution of terrestrial igneous rocks. Important advances in trace element geochemistry arising from lunar and meteorite studies are reviewed in the sections on meteorites and planetology. This report primarily reviews progress from 1975 through 1978, but a few important 1973–1974 papers are included as are significant foreign contributions.
