Abstract

Electron microscope data of spot analysis of the major phases in the investigated samples.

Usage Notes

Analsyses performed with a JEOL JXA-8530-F field emission electron microprobe analyzer (EMPA), equipped with five wavelength-dispersive spectrometers (WDS) and two energy-dispersive spectrometers (EDS) at the Natural History Museum Vienna. Operation conditions were 15 kV acceleration voltage, 20 nA beam current, and fully focused beam. For quantification, a ZAF correction was applied and the content was calculated as oxides. Natural and synthetic reference minerals were used for calibration, different for silicates, chromite, metal and sulfides. Detection limits for major elements are provided.
