Sahara Brown

The close-up view of each stone type shows a relatively true image of the crystalline structure and the colouring. This is suitable for grained slabs to a limited extend only. In regard to the colour matching, please take an original sample of the stone from your furniture store as a basis.

Petrography

The rock consists almost exclusively of calcite = calc-spar. The lime, bright in its  
pure state, obtains a dark brown shade because of the minor constituent mineral limonite (iron ore). Also the yellow veins result from that ore. The white veins  consist of remarkably pure calcite.  

Petrogenesis

Limestones (lime breccia) originate in calcareous ooze deposited on the sea ground where, at first, it is transformed into sediments and later on into limestone. Posterior tectonic movements in the earth’s crust caused fractures in the solid limestone. Calcareous water circulated through the open crevices which, in the course of time, were completely filled by crystalline calc-spar.
