Abandoned brucite marble quarry at an altitude of about 900 m, to the east of Prabubolo alto, in the valley of Rio San Valentino.

This brucite marble, commercially known as pearl grey marble, is the product of contact metamorphism, originated from Cenozoic basaltic intrusions in Late Triassic dolostone (Dolomia Principale Formation).
