The Plaňany quarry is situated near the railway station at Plaňany village. 13 km from Kolín in the direction to Prague. A proteozoic gneiss formation is covered by marine Createceous sediments developed in nearshore fades here. At the beginning of 1999 cliff-shaped elevations of basement rocks were exposed containing two through-like accumulations of Cretaceous sediments. They belong to the Peruc-Korycany and Bílá Hora Formations and are represented by conglomerates of two sedimentary cycles, bioclastic limestones and silstones with high proportion of coprolites. glauconite and shark teeth.
