Quartzites

Da Vinci

In a distant past, 3.2 billion years ago, ancient quartz rocks, carried by water, were deposited in flooded sedimentary basins, like a shallow sea, receiving and accumulating sediments from rivers. Once solidified, they maintained designs and structures. 1.9 billion years ago, metamorphism transformed them into quartzites, appearing in Serra da Jacobina, in Bahia. Da Vinci has relict minerals which, over geological time, have acquired exotic colors, like the green of fuchsites, due to the preserved chromium content.

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.
