Quartzites

Infinity Grey

The Chapada Diamantina region, approximately 1.6 billion years ago, was the setting for a unique geological phenomenon that resulted in the formation of Infinity Grey Quartzite.

During this process, river sediments mixed with tidal movements, creating the foundation for this remarkable natural stone. Pebbles, polished by the continuous action of water, in varying sizes and shapes, became embedded within the characteristic gray matrix of the quartzite.

Over time, intense tectonic stress promoted the metamorphism of these sediments. As a result, minerals such as muscovite and tourmaline crystallized into an intricate quartzitic network, giving Infinity Grey Quartzite its unique and sophisticated appearance.

Each layer of this stone is a geological record of the winding paths of rivers and the constant movement of tides, preserving millions of years of natural history in a material of exceptional beauty and strength.

Petrographic Analysis

It consists of classifying the rock through the macroscopic and microscopic description of its characteristics, such as minerological composition, alteration, deformation and microcracking pattern.

Apparently density

Relationship between the mass and apparent volume of the rock. It provides the weight of the rock, being an important parameter for calculating loads in buildings.

Apparent porosity

It is the relationship between the volume of voids and the total volume of the rock expressed as a percentage.

Water absorption

It is the ability to assimilate or incorporate water into the rock, expressed as a percentage.

Abrasion resistance

Determines the wear rate due to friction of particles with the surface of a rock plate.

Bending resistance

It simulates bending stresses in rock slabs with a predetermined thickness, in this case simulating the effect of wind on slabs fixed to façades with metal anchors.
