Abstract

Magnesite of selected Austrian deposits/occurrences (sparry magnesite of Hohentauern/Sunk, Hochfilzen, Breitenau, Radenthein/Millstätter Alpe, Kaswassergraben and cryptocrystalline magnesite of Kraubath) were analysed for their stable Mg-isotope composition (δ26MgDSM-3). This pilot study focussed on the extension/completion of isotope data of Austrian mineral deposits. Additionally, some foreign types of magnesite (Bela Stena/Serbia, Bushveld/South Africa, Poldasht/NW Iran) were also analysed for comparison in order to evaluate site-specific characteristics. We found that the most important types of magnesite yield specific δ26MgDSM-3 −values: Kraubath-type −2.88‰ up to −1.80‰, Veitsch-type −1.54 up to −0.49‰, Bela Stena-type −1.07 up to −0.42‰ and Poldasht-type −1.04 up to +1.01‰, the latter deciphering the different formation mechanisms.
