Scientific paper

In the K-T boundary section of the Lattengebirge Alps (Bavaria), three distinct Ir anomalies are examined. An analysis was conducted on a thin layer of calcareous sandstone from the region, containing abundant mm-sized coal fragments. The mineralogy and geochemistry of the sandstone layer components are discussed, including sulfides and silicate melt glasses. The distribution of Ir-gearing horizons in the region indicates that three Ir-delivering events occurred over an extended period from late Maastrichtian into early Danian. It is suggested that the causative agent for the K-T events might have been volcanism combined with sea level and climate changes.
