What Is Jura Limestone?
Jura limestone tiles have long been considered the king of European limestones.

Jura Limestone’s Origins
Jura limestone originally comes from the Jura Mountain Range, which runs for 225 miles on both sides of the Franco-Swiss border and separates the Rhône River from the Rhine. They lie mostly in Switzerland and France, with the far eastern sector lying in southwest Germany.
The rocks that form the Jura Mountains are filled with fossils and are the basis for the names in the Jurassic Period – the time when dinosaurs were rapidly evolving and spreading over much of the world. Jura Limestones range between 168 and 145 million years old and originated as carbonate muds and reefs on the ancient ocean bed. With time and compaction, the fossil bearing muds turned into limestone rock.
About Jura Limestone Tiles
Jura Limestone tiles are hard and compact and have been quarried since ancient times. Common fossils include ammonites, ammonite jaws (aptychii), feather stars and plant material. The outlines of animal tracks and burrows from creatures such as sea worms are often also preserved.
Jura Limestone tiles may contain veins of calcite which have the technical name of stylolites. These are ‘seams’ of calcite, with minor amounts of clay and minerals such as pyrite, which are formed when the limestone rock is subjected to great pressures and minerals are dissolved and reprecipitated, predominantly as calcite (Ca).
The crystals of calcite play an important role in the compaction and hardness of the rock. Their presence is natural – they are common in many limestones and marbles – and does not mean that there is a defect or weakness in the rock. They may extend laterally for up to tens of metres, may be sub-parallel to the bedding of the rock and in some circumstances they can develop perpendicular to bedding. Stylolites are visible only where less soluble minerals such as clay and pyrite are present in the limestone and become concentrated at the interface.
