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
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.
