摘要
Hydrocarbons in ore minerals of the Bleiberg Pb-Zn deposit and in authigenic quartzes of the Lienzer Dolomiten (Drau Range, Eastern Alps) were characterized by their organic-chemical composition. Microthermometric data and the molecular composition of the hydrocarbons indicate a hyperthermal event of migrating condensate-like hydrocarbons in the Middle Cretaceous to Early Tertiary. The hydrocarbons possibly played an important role as reducing agents in second stage sulfide precipation.
