| Description | Algal limestone of Vrchná Hora are known since second half of 19th century, when Adrian (1863) marked them on geological map of 1:144 000 scale. Coralline algae (Rhodophyta, Corallinales, Sporolithales), as main component of these limestone, are dominant in Cenozoic shallow-water ecosystems, and many identified species from Vrcná Hora still inhabit recent seas. They provide a useful paleoecological tool in Badenian Vrchná Hora limestone environment interpretations. Fruticose rhodoliths, unattached protuberances and their debris are dominant in studied samples. They correspond to lithoclastic coralline algal rudstone within grainstone matrix lithofacies that prograde to lithoclastic coralline algal gastropod rudstone within grainstone matrix. Together with coralline algal species they can be compared to recent maërl sediment of coastal detritic environment of paraautochtonous sediments of Mediterranean Sea. Skeletal association corresponds to common warm temperate to subtropical rhodalgal biofacies. Limestones of Vrchná Hora were deposited in dynamic environment of normal salinity, with oscillations of sea level. |
