Quartzites

Leblon

The Leblon quartzite has a formation linked to sea level variations on the Brazilian coast. 1.6 billion years ago, rising global temperatures melted glaciers, raising sea levels. The coast advanced over the continent, resulting in the erosion of stones and deposit of new boron-rich sediments, giving origin to tourmaline and dumortierite, minerals that give quartzite the bluish green shades. The natural action of seas and rivers shaped Leblon, preserving the sedimentary forms of the time.

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

Simulates flexural efforts in rock pacas, with predetermined thickness, in this case simulating the effect of wind on plates fixed to facades with metal anchors.
