Miniera di Buca della Vena, Ponte Stazzemese, Stazzema, Alpi Apuane, Lucca, Toscana, Italia

The Buca della Vena mine was exploited for barite and Fe-oxides up to 1988. The mineralization is hosted within two carbonatic lenses of dolomitic metalimestones of Upper Triassic age (Grezzoni formation) and marble of Liassic age (Marble formation), interbedded with lenses of phyllites. The ore body and the hosted rocks show evidences of deformations which have been referred to a first compressive tectonic phase dating back 26 m.y.. Measured homogenization temperature in beryl crystals from the ore body ranged from 250° to 340° C, in good agreement with the metamorphic grade of the area (greenschist facies).
Carmignani et al. (1972, 1976) considered this deposit to be a metasomatic replacement of carbonate rocks, genetically connected to a hypothetical synkinematic intrusive body.
According to Cortecci et al. (1985), on the other hand, on the basis of isotope analysis of sulfates and sulfides, concluded that the deposit is sedimentary in origin and was subsequently metamorphosed and partly remobilized during the Tertiary Appenninic orogeny.

Orlandi & Dini (2004) distinguish four different kind of occurrence of Buca della Vena minerals:
-Type V-1 veins: calcite and baryte veins embedded in the dolomitic limestones.
-Type V-2 veins: quartz and baryte veins embedded in the ore body (Fe-oxides + baryte)
-Type V-3 veins: quartz veins embedded in the phyllites.
-Type F-1 fractures: vertical fractures with the wall covered by calcite, baryte and albite crystals.
