General Description of the Quarry
The quarry is opened on a flat area and shows two exploitable beds: the upper one is 1.5 meters thick, and the lower one reaches the thickness of about 4 meters. At the surface of the massif, the rock is yellowish to whitish and is fairly fractured. The general attitude of the formation is N 30º E, 15º SE. The exploited beds show little fracturation, although some joints do occur, like those perpendicular to a doleritic vein striking N 20º W, which thickness attains 1 meter and is responsible for the metamorphism of the adjacent zones. Calcitic aggregates and geodes are rare and of small size in any case. The blocks extracted usually are of large size. The cut of slabs is preferentially made parallel to the stratification plane. The most common finishings are the honed and polished ones, the tonality of the stone becoming grey or brownish-grey in the latter case. The reserves available in the area are fair.
