Paradiso

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

Paradiso is typical mixed gneiss with a tight mixture of the different rock components. Light grey-violet to light brown-violet, as well as orange-coloured, grown through feldspar types and light grey-transparent quartz alternate with each other. Black-grey to black biotite occurs in the whole rock finely distributed. It can also occur concentrated in the form of stria, nests and clouds. The different colouring of the feldspar types is caused by their different content of iron oxide compounds. 

Petrogenesis

Paradiso-Migmatite developed by partial re-melting of originally granite rock and slate sediment rock under high pressure and high temperature. This process took place at the border of the earth crust and earth mantle and lasted over geologically long periods. Here, mixing, partial solution, re-forming of minerals and crystallisation of gathered material occurred; structural changes were the result of it. The plasticity of the very ductile melt is visible by the folding structure and the direction orientation of the fine black-grey mica minerals. Such migmatite types are geologically very old.
