Grigio Carnico

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

Bituminous and, therefore, dark-grey calcite (=lime spar) dominated. White veins and clouds of crystal calcite verify the Brekzie character. Typical are the black lines, reminding of a spider web.

Petrogenesis

Limestone is solidified deposits of inorganic, precipitated lime or of residues of lime-containing (Micro) fossil shells. In this case, sedimentation occurred on the seabed in an oxygen-starved environment. Under these conditions, a part of the organic material was preserved as bitumen. This substance is responsible for the dark colour of the otherwise light calcite. Tectonic forces caused stresses and fractures in the rock, which have long since healed.
