/ Product definition The declared tiles and floor panels consist of Jura Limestone. This limestone came into being in the Mesozoic Age approximately 160 million years ago though limestone deposits from a tropical sea near the southern Franconian highlands. The geological formation is called Upper Jura, White Jura or Malm Delta. This sedimentary rock consists mainly of calcium carbonate (CaCO3) with admixtures of metal oxides and coloured clays. Jura limestone, also known as Jura marble, occurs in the Franconian limestone highlands in the vicinity of Eichstätt-Treuchtlingen. The material density, polishing ability, the numerous variations in colour and structure and its good abrasion resistance provide the decisive properties for the many possible uses for Jura limestone. Jura Limestone is the result of unique prehistoric developments. Each stone contains numerous testimonies to prehistoric flora and fauna. The force of nature which created this natural stone and the visible geological documentation give it its special appeal and a timeless character. 2 The declared products are marketed under the material names of Jura Limestone, Dietfurt Limestone, Dietfurt Limestone gala and Dietfurt Travertine by the Franken-Schotter company.
