Abstract:
For classification of the minerals and to clarify the geological evolution of the samples major ele-ments of clinopyroxene, orthopyroxene, and olivine (given as oxides in wt.%) were determined by electron microprobe analyses (Acceleration voltage: 15 kV, Beam current: 15 nA, Measuring time for sample and background, respectively: 20 seconds). For calibration silicate and oxide standards were used. The analytical error of the obtained data is 0.3–1.0 % (relative) for element concentra-tions >10 wt.%. For oxide contents of 1–10 % and <1 %, the analytical uncertainty is 1–5 % and >5 % (relative), respectively.
The measurements were performed at the Universität Erlangen (Germany), GeoZentrum Nordbay-ern, between 2012 and 2025. Electron microprobe. JEOL 8200 with five wavelength-dispersive spectrometers. 15 kV acceleration voltage, 15 nA beam current, 20 seconds counting time, silicate and oxide standards for calibration
