General Description of the Quarry
The exploited limestone, essentially biogenic, is inadequately called "breccia " (and also known as Tavira's Breccia) and consists of a rather fractured and karstified bed. Sometimes, thin small veins and calcitic aggregates occur. The average attitude of the bed is E-W, 30º N. Medium size blocks are extracted, their cut according to the bedding plane being the most common for ornamental purposes. The reserves of this type of limestone became scarce in the recent years.
