Upper Cretaceous nearshore facies sediments transgressing over metamorphic rocks from the Kutná Hora medieval silver mine
Abstract
The Upper Cretaceous sediments from the medieval silver mine in Kutná Hora are described for the first time. Nearshore facies sediments of the Bohemian Cretaceous Basin cover metamorphic rocks of the Kutná Hora crystalline complex. Special type of basal conglomerate and bioclastic limestones contain abraded fossil remains dominated by rudists, echinoid spines and calcareous sponges. The fauna primarily occupied shallow water conditions. Transport from surrounding elevations caused its destruction, abrasion and sorting-out. Important sedimentological, petrological and palaeontological data will be used for litofacial and paleogeographical studies of Cretaceous sediments in southern part of the Bohemian Cretaceous Basin.
