Breccia Pernice

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

This lime-breccia has been given this name, because it reminds of the plumage of a partridge. It consists exclusively of extensively broken, angular limestone fragments. The different concentration of iron hydroxide causes the generation of diverse brown and orange shades. Also the natural binder in the grown together net-like parts of the fragments consists of light, yellow to white calcite. There are different variants of this type of rock regarding the colour position, size and arrangement of the fragments. 

Petrogenesis

Limestone like this was generated by deposits of lime sludge at the bottom of the sea. In most cases also lime-containing shell organisms took part in the building-up. A solid rock was generated due to the pressure of overlaying covering layers and participation of the limy binder. In this case, there were tectonic tensions in the earth crust at a later time. The rock broke up into many squared fragments along the faults. However, the fractures healed over time due to imbedding calcite. In this case, one talks about a tectonic breccia. To-day signs of this history of origin are the fine, partially noticeable crack lines.
