Juparana Fantastico

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 processed stone has a composition close to granite. However, the clearly recognisable direction orientation, as well as the red garnet point to a metamorphosis. Therefore, the rock has to be named gneiss. Essentially, the properties in usage correspond to those of granite. Feldspar gets its pleasantly warm shade from the presence of traces of the mineral limonite, an iron oxide. 

Petrogenesis

This rock has been generated in the deeper ranges of the earth crust under high pressures and temperatures und uncovered by erosion of the covering mountain ranges over hundreds of millions of years.
