Marmo Palissandro oniciato

Fine-grained calc-silicate dolomitic marble, characterized by the presence of dolomite and phlogopite. The phlogopite lamellae are coarser than in the Palissandro Classico and are restricted to discrete layers that define the main foliation. The stone presents the same mineralogical composition of the Palissandro Classico marble.

THE HISTORICAL STONES

Frankfurt Airport
The most abundant Ossolano material is represented by serizzos, an ortogneiss, similar to beolas with regard to age, but with a different grain pattern and level of deformation. The high concentration of serizzo quarries is located in the top part of the Ossola Valley and in the Valleys of Antigorio and Formazza. Serizzo has been used also for flooring the Milan and Frankfurt airports, just like the coverings of the underground in Milan , Bruxelles and Singapore.. LE PIETRE STORICHE
