Morphology, Composition, Age and Origin of Carbonate Spherulites from Caves of Western Urals1

They do not correspond to recent conditions of mineral formation and differ from traditional morphological types of speleothems (various types of dripstones and flowstones, cave pearls, moon-milk, corraloids, helictites, and others).
