General Description of the Quarry
The bed producing a stone with characteristics broadly similar to a finer Moca Creme type is exploited in several quarries of the area and generally constitutes a thick layer (until 10 meters) intercalated within other limestone types. The Relvinha bed is sub superficial and sub horizontal, its exploitation being developed mainly in extension. The surface karst and the fracturation are negligible. Then, the extraction of large size blocks is possible. The stone is very homogeneous and the typical ornamental pattern, showing aligned parallel clasts disposed in a cross-bedding structure, is obtained by cutting slabs according to the grain plane. Although some large reserves exist in the area, they will decrease significantly in some years if the intense actual exploitation continues.
