Source of geodes known as cacholong or kalmuck agate, but common opal and not agate.
"The most attractive geodes come from the Rudice Formation – claystones with lenses of limonitic iron ores, quartz sandstones and chert gravels that originated by weathering especially of the Jurassic sediments under tropical conditions in the Lower Cretaceous. The Rudice Formation is situated just in the Jurassic limestones in the Moravian Karst." (RICHTEROVÁ et al., 2001).
