Stratus Boquira
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
The beautiful rock mainly consists of light gray, transparent quartz. The bluish shade is not as intense as in the case of Azul Macaubas, another quartzite quarried in the same area. The blue hue of either rock is caused by the minerals dumortierite und disthene.
Petrogenesis
As common with all quarzites, the Stratus Boquira was generated from sandstone. Due to high pressure and temperature during the folding up period of a mountain, the rock properties were subject to significant metamorphoses. The components were enormously compressed, thus forming new minerals like disthene and the rare dumortierite. which come close to quartz in terms of hardness and durability. Thanks to these characteristics, this stone readily takes a mirror finish.
