Porphyry cubes

Porphyry: an ideal material for paving

Porphyry is a particular type of volcanic rock belonging to the "Atesina Porphyry Platform", an enormous complex of volcanic rocks that extends into the Trentino-Alto Adige region. These rocks, extremely varied and differentiated, both as a chemical composition and as a form of formation, are the result of an intense volcanic activity started 260 million years ago in the Permian period, and continued for several million years with a continuous repetition of eruptive phases and stasis phases. Among the various methods of deposition of these rocks, the so-called ignimbrites take on particular importance, as these are the ones that gave rise to the "porphyry". These are flows of liquid-gaseous mixtures with thicknesses generally ranging from 5 to 20 meters and with a fairly constant chemism, up to the so-called ignimbritic unit, which reaches hundreds of meters thick.

Porphyry cubes of various sizes

They are solid in a cubic shape, obtained by mechanical splitting from the stone and according to the dimensions they are distinguished in 4/6 - 6/8 - 8/10 - 10/12. The top surface of the cube is natural hollow, the side faces are rough.
The cubes can be supplied loose, in crates and in bags.
The porphyry cubes are ideal for paving streets, squares, porticoes, pedestrian islands, sidewalks, avenues of gardens.
