sketchfab

See the whole collection of Ornamental Stones from Turkey No.: 2135 Size: 15 x 15 x 1 cm Type: Rock Formed Through Sedimentation Description: Travertine is primarily made up of Calcite; it features fine-scale banding of browns, grays, whites, and pink hues due to very fine-grained to no visible crystals of Calcite. Travertine serves as the classic construction stone, ideal for facing and paving. Calcareous alabaster is used in polished slabs and as decorative objects. Essential minerals: Calcite or Aragonite, often accompanied by Limonite impurities. Non-essential minerals: frequent fossils and imprints, especially of plants, may be present; minor amounts of clays can also be found. Iron oxides may cause discoloration in the form of red or brown stains. Website: http://geology.uaic.ro/muzee/mineralogie/ Concept & 3D-modelling by dr. Andrei Ionut APOPEI
