Application of Electron Probe Microanalysis to the Study of Geological and Planetary Materials

: The impact of electron probe microanalysis on the study of geological and planetary materials has been tremendous. Electron microprobes evolved into routine analytical instruments in geological research laboratories as instrument capabilities improved and applications to geologic/planetary materials expanded. The contributions of electron probe microanalysis to the characterization of minerals, both terrestrial and extraterrestrial, and to other significant geological research, such as light element analysis, trace element analysis, and element mapping, is described.
