Leader in the extraction and machining of porphyry
Porphyry, or rhyolite, is an effusive magmatic rock that was formed due to a reduction in pressure and rapid cooling resulting from a leakage from the crust of the magma. It consists of a microcrystalline paste in which a series of isolated crystals, called phenocrysts, are immersed.
Its mineral composition consists of quartz, sanidine, plagioclase and biotite, pyroxene and glass paste: its characteristics make porphyry an extremely durable stone.
The best squares are paved using porphyry.
