Porphyry slabs

Porphyry: an ideal material for slabs

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 slabs of various sizes

The irregular slabs are made up of natural r aw porphyry slabs from the quarry of various sizes and thicknesses. Depending on these characteristics, it is produced and selected in the following types:

• slabs of normal porphyry on pallets 2-6 cm
• slabs of porphyry normal thin type 1-3 cm
• slabs of porphyry normal giant type 2-6 cm
• slabs of thin giant porphyry type 1-4 cm

Depending on the type, the slab is supplied and packaged on pallets with variable weight from to. 1.2 to 1.8 each, tied with a nylon hood.
