Colour, characteristics:

Colour variegated, predominantly grey, bluish, yellowish, occasionally reddish. Mineral composition corresponding to the source rocks. More resistant rock residues such as quartzite, amphibolite, diabase, garnet, siliceous limestone predominate in many types. Binding agents are clay, lime and pebbles. The structure is classified by grain size. Round shapes predominate. Always numerous cavities. Usually no stratification.

Formation:

Consolidation of accumulated debris in old gravel fields, alluvial cones and alluvial fans as well as in filled valleys due to overflowing or circulating water from precipitated binding agents.

Locations:

Inn Valley/Upper Bavaria, Lower Austria, Switzerland (Valais), Croatia (Dalmatia), Italy (Sicily)

Products:

Solid varieties are used as building blocks or monuments. The varieties that are particularly resistant due to their siliceous bond are also used as facings.
