Abstract

Stable carbon, oxygen, and hydrogen isotope compositions of carbonates and inclusion fluids trapped in calcites related to the ore deposits of the Matra and the Borzsony Mountains have been measured in order to assess the origin and evolution of ore-forming fluids. The complex evaluation of these data revealed that fluid mixing was characteristic for both ore deposits. In the Matra deposit meteoric water, formation water of meteoric origin, and magmatic water were mixed during ore formation. In the Borzsony deposit magmatic water and formation water were also present in significant amounts, whereas no direct addition of meteoric water is observed. An additional component with very negative δ13C and δD values also appears that can be attributed to oxidation of organic matter.
