Re-Os ages of Variscan hydrothermal gold mineralisations, Central Bohemian metallogenetic zone, Czech Republic

Abstrakt

Re-Os isotopes in molybdenite have been used to constrain age of mesothermal gold deposits in the central part of the Bohemian Massif. Two age spans were determined: 349-339Ma (gold mineralization) and 385-383Ma (gold-barren event).
