This brucite marble quarry is located not far from the Borcola Pass quarry (also known as Lucchi quarry, see http://www.mindat.org/loc-159421.html), at a slightly higher level. The boundary line between Vicenza and Trento provinces runs between the two quarries.

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

Aragonite, besides the tipical acicular crystals, sometimes apperas in coralloid forms; brucite, which normally forms white or bluish massive veins and colourless or bluish hexagonal crystals, has occasionally been found in a pinkish Mn-rich variety; giorgiosite rarely appears as white globular incrustations.
