摘要

•Multi-proxy study of the Alpine–Mediterranean black shale•Mineralogy and geochemistry of the ore and the black shale are very similar.•Ore was formed via microbial blooms governed by hydrothermal activity.•Mineralogical and geochemical data reflect an ancient failed rift system.•Úrkút proxies differ from those of the Tethyan epicontinental shelf occurrences.
