    Description / Table of Contents: A method for quantitative microprobe analyses of geological samples (silicates and carbonates) is described. In the case of silicates for total analysis the need is to detect simultaneously more than 10 chemical main- and minor-constituents. For this purpose two experimental possibilities are available: (a) automatic control of the crystal scanners (sequence control); (b) combination WDS/EDS (wavelength-dispersive and energy-dispersive system). These two possibilities are discussed. Technical notes of the equipment and the analytical method are described in detail. High analytical precision can be obtained.
    Notes: Es wird eine quantitative Analysenmethode für geologische Proben (Silikate and Karbonate) mittels Röntgenmikrosonde beschrieben. Im Falle von Silikaten sind fur eine Totalanalyse mehr als 10 chemische Elemente simultan zu erfassen (Haupt-und Nebenelemente). Zwei experimentelle Moglichkeiten sind realisierbar: (a) Automatischer Sequenzbetrieb mittels Kristallspekrometern; (b) Kombination WDS/EDS (wellenlangendispersives und energiedispersives System). Diese beiden Möglichkeiten werden diskutiert. Technische Angaben und apparativer Aufwand werden beschrieben. Es wird dargelegt, auf welche Weise eine hohe analytische Genauigkeit erreicht werden kann.
