Spherical and ellipsoidal cavities in European sandstones: a product of sinking carbonate dissolution front

Popis výsledku v původním jazyce

Symmetrical cavities of spherical, ellipsoidal or subtriangular shapes, tens of centimetres to 2-3 m in diameter, have been documented in a number of European sandstone districts extending between Luxembourg and Poland. The studied symmetrical cavities share specific features which point to an origin linked with the dissolution of concretionary precursors. Field evidence includes their spatial association with carbonate-cemented concretions and the presence of a variety of convex, convexo-concave and concave forms. The presence of enclaves of loose sand in sandstone - sand nests - and the absence of karst features in outcrops suggest that carbonate dissolution took place largely under the surface, while remodelling of the solutional cavities into morecomplex forms including caves is governed by present-day weathering processes. A clear vertical zoning in the intensity of carbonate dissolution was observed, with a well-defined transition from completely dissolved carbonate above (fully
