    Notes: Abstract In the Eastern Alps compression during orogeny in the Upper Cretaceous caused crustal thickening, isostatic uplift and gravitational adjustment of the unstable orogenic wedge. This process triggered extensional basin formation on the back of the orogen (Gosau Basins). The basin fill of the Muttekopf Gosau Basin is arranged in megacycles, the first one comprising alluvial fan sediments and “Inoceramus marls” of the Lower Gosau Complex (Faupl et al. 1987) of Santonian age. Three other cycles follow (Upper Gosau Complex, Campanian to Maastrichtian), consisting of turbiditic fining upward sequences, that are indicative for extensional tectonics during basin formation, as subsidence events prevent formation of autocyclic coarsening upward sequences and therefore prograding of the turbidite system. Deposition of the 1st and 2nd Megacycle occured below the CCD (Carbonate Compensation Depth). The carbonate rich 3rd Megacycle was deposited probably below the CCD after a period of palaeogeographic reorganisation (uplift?) in the source area.

    Description / Table of Contents: Zusammenfassung Röntgenfluorescenzspektrometrische Analysenverfahren sind in einem weiten Arbeitsbereich anwendbar. Auf Grund der Einflüsse der Massenabsorptionskoeffizienten sind lineare Analysenfunktionen jedoch in der Regel nur für kleine Elementmengen und unter bestimmten Bedingungen zu erwarten. Bei Einbeziehung von Trenn- und Anreicherungsmethoden in das Verfahren sowie variabler Referenznormierung können in vielen Fällen Linearfunktionen und kleine Standardabweichungen erreicht werden. Die Vorgehensweise bei der Standardisierung von Verfahren der Röntgenfluorescenzanalyse wird am Beispiel der Eisenbestimmung in einer Molybdänmatrix im Nanomol 3-Bereich detailliert beschrieben. Eine PAN-Fällung als Trennmethode ist Bestandteil der Arbeitsvorschrift. Der Gebrauch der durch die Standardisierung gefundenen Kenndaten bei Prüfmethoden wird für verschiedene Molybdänmaterialien demonstriert.
    Notes: Abstract X-ray fluorescence spectrometry is applicable to a wide working range. Due to influences of mass absorption coefficients linear analytical functions are usually to be expected only for small amounts of elements and under defined conditions. However, including separation and enrichment methods as well as variable reference standardization linear functions and small standard deviations can be attained in most cases. The way of standardization for X-ray fluorescence analysis is described in detail. The determination of iron traces in a molybdenum matrix in the nanomol 3-range is given as an example. A PAN-precipitation as separating method is part of the working procedure. The use of the characteristic data found by the standardization for check methods is demonstrated for various molybdenum materials.
