Petrography

Calacatta Gold is extremely fine-grained marble with white basic shade and very lively formed arabesques from light grey to brownish-yellowish colour. These differences in colour and pattern occur depending on the quarry it was mined. The name Calacatta serves as texture name in Italian language for marble with large-scaly structure. This decoration term has become established for various deposits and varieties. 

Petrogenesis

The Apuani marble area of the region of Carrara-Massa-Pietrasanta was generated during the Jurassic formation by a metamorphosis process covering a large region. Limestone complexes with different contents of organic contents and different quantities of clay minerals were re-crystallised to marble under high pressure and temperatures caused by folding-up of the Apennin mountain range. The residual clay, participating in decorating the arabesques, can be coloured lightly reddish or yellowish-brownish due to hematite or limonite enrichment.
