Descriptions

Raman spectroscopy of carbonaceous matter (RSCM) is commonly used to derive metamorphic peak- temperature estimates of metasedimentary rocks. This thermometry method exploits that the degree of graphitization of carbonateous matter (CM), which is measured via Raman spectroscopy, increases with metamorphic temperature. This dataset provides the raw data of RSCM, spectrum fitting results and calculated peak temperatures of more than 100 samples from the central Tauern Window. We used this data to constrain the distribution of metamorphic peak temperatures in this area. Raman analysis was performed on polished thin and thick sections. We exclusively measured grains of CM that were enclosed in translucent minerals (quartz, white mica, chlorite, carbonates, chloritoid, garnet) and therefore not exposed on the section surface, in order to avoid destruction of the CM during the sample preparation process. Raman spectra were acquired in the first-order region of graphite (ca. 1000-1900 cm^-1). Further details on the analytical setup, spectrum fitting and temperature calculation are provided in the following sections. The data is distributed in the form of simple text files and raster images.
