Splügen

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

Light green-white structured quartzite with some slate characteristics and coarse-rough splitting face. Large white-green cloud-shaped structures, relatively uniform areas or weakly striped areas can appear on the polished surface. All of the three appearances are characteristic and can appear within one block. 

Petrogenesis

Splügen-quartzite was generated by metamorphosis (rock transformation, having occurred under pressure and temperature influence in the lower earth crust) of a quartz-rich sandstone massif with low clay content. The individual quartz grains melted together at their edges during the metamorphosis due to which the high strength of the rock was reached.
