Tiny spherulitic balls ("Hornsteinkugelchen") were found exclusively in the Triassic micritic limestones and dolomites; they originated partly by the silicification of gypsum microconcretions. This is supported by various signs of hypersalinity. Another origin is supposed for aggregates of spherulites arranged along the polyedric faces; they were formed during the late diagenesis along the network of hair-thin cracks. Rare red cherts in Keuper dolomite probably represent climatic silcretes; they contain scarce lepisphere-like relicts. Silcretes from the Berriasian limestones of the Czorsztyn Unit (Pieniny Klippen Belt) are described. Paleocene silcrete from the locality of Drienovec was formed on pelitic regolite; its chemical composition indicates the connection with the underlying redeposited products of the Upper Cretaceous lateritization.
