Cretaceous deposits near Havlíčkův Brod

Cretaceous sandstones, claystones and limestones were discovered in 1990s´ near the town Havlíčkův Brod in the Bohemian-Moravian Uplands. The fi nds of bivalves Inoceramus lamarcki Parkinson, I. apicalis Woods and Spondylus spinosus Schreibers brings evidence that rocks came from the Jizera Formation (Middle Turonian). Cross bedding indicates shallow marine environment of the wave-cut zone. Cretaceous rocks were found as pebbles in the topsoil and mixed with pebbles of crystalline rocks discovered during geomorphological mapping of this area. Their altitude is in a correspondence with the relics of Neogene fluvial deposits of the Sázava River. Cretaceous rocks were transported from the southest part of the Bohemian Cretaceous Basin in the area of Žďár nad Sázavou. Anthropogenic origin of accumulation is unprobable.Cretaceous sandstones, claystones and limestones were discovered in 1990s´ near the town Havlíčkův Brod in the Bohemian-Moravian Uplands.
