Abstract

Carbon and sulfur contents as well as carbon and oxygen isotope composition of carbonates and sulfur isotope composition of sulfidic sulfur were determined in 8 samples of mafic dike rocks from the Krušné Hory/Erzgebirge area. The data together with the results of petrographic and mineralogical studies indicate that carbonates in all the examined rocks and sulfides in some of them were formed during hydrothermal alterations. However, subcrustal origin of sulfur in some mafic dike samples cannot be excluded.
