Jura marble is the trade name of the light beige to grey-blue limestone found in the Franconian Alb region. It is mined mainly in the Titting-Kaldorf area. This fine-grained limestone is rich in fossils. Jura marble was created by lime deposits formed some 150 Million years ago in the Mesozoic age.
The rock consists of individual beds up to 1.60 metres thick, with the depth of the usable strata measuring around 45 metres in total. The beds of stone
are separated from one another by thin layers of marl. They are broken into suitable block sizes by drilling and splitting, with close attention paid to geological features such as cracks and fissures in the stone. State-of-the-art wheel loaders, drill rigs and transport equipment are used for work in the quarry. The natural colour spectrum of the stone ranges from beige to grey-blue varieties, encompassing all conceivable mixtures of shades in between.
