Abstract

Potential graphite-bearing schists are investigated from Fertőrákos (Sopron Mts., NW-Hungary) with ore microscopy, scanning electron microscopy, Raman spectroscopy, X-ray powder diffraction and X-ray fluorescence spectrometry. Disordered graphite is identified by Raman spectroscopy, which appears as <50 µm sized flakes, and as 50–300 µm sized lense-forming granular aggregates in the deformed zones of the samples detected by ore and scanning electron microscopy. Using graphite geothermometry on Raman spectra, the average formation temperature of the Fertőrákos samples is ~440 °C (±50 °C).
