Granites
Makalu
Makalu, a stunning expression of turbulent ages in Brazil, has a complex origin dating more than 200 million years. Tectonic plate collisions built up mountain ranges, reshaping stones and crystallizing minerals from metamorphism. Makalu revealed feldspars, biotite and epidote in its gray matrix, with quartz veins for contrast. Crystals of microscopic calcite, zircon and titanite complete its fascinating composition. This granite preserves a unique spectacle in Brasilianas Mountain Range, reflecting the events that shaped it.

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.
Compressive strength
.
Stain resistance
Stress that causes rock to rupture when subjected to compressive stress.
