Ion Probe Determination of the Abundances of all the Rare Earth Elements in Single Mineral Grains
Although the measurement of rare earth element (REE) abundances in mg aliquots of geological samples has contributed much to the understanding of petrogenetic processes, probe techniques, which would allow the measurement of compositional variations between grains and within grains (crystal zoning), have so far been of limited usefulness for REE determinations. The electron microprobe detection limit for these elements is ~ 500 ppm and the concentrations of only a few REE can be determined, usually with large uncertainties.
