Quartzites
Bronzite
Bronzite stands out for its unique formation, of around 2.8 to 2.5 billion years ago, when the first life forms transformed the atmosphere, liberating oxygen through photosynthesis. Iron reaction with the seawater formed oxides that sank to the ocean floor, creating layers of silica and iron. After several geological events, throughout the evolution of the earth, Bronzite was displaced and metamorphized it was found in Bahia, maintaining high hardness and reddish colors thanks to the iron present in its formation.

![Petrographic Analysis](http://decolores.dev.duoapp.com.br/media/853/1-analise-petrografica.png)
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](http://decolores.dev.duoapp.com.br/media/857/1-densidade-aparente.png)
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](http://decolores.dev.duoapp.com.br/media/858/1-porosidade-aparente.png)
Apparent porosity
It is the relationship between the volume of voids and the total volume of the rock expressed as a percentage.
![Water absorption](http://decolores.dev.duoapp.com.br/media/859/1-absorcao-dagua.png)
Water absorption
It is the ability to assimilate or incorporate water into the rock, expressed as a percentage.
![Abrasion resistance](http://decolores.dev.duoapp.com.br/media/860/1-resistencia-a-abrasao.png)
Abrasion resistance
Determines the wear rate due to friction of particles with the surface of a rock plate.
![Bending resistance](http://decolores.dev.duoapp.com.br/media/861/1-resistencia-a-flexao.png)
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.

![Stain resistance](http://decolores.dev.duoapp.com.br/media/863/1-resistencia-ao-manchamento.png)
Stain resistance
Stress that causes rock to rupture when subjected to compressive stress.
