Macroscopic Description
Fine-grained beige limestone, with stylolites and thin calcitic and ferruginous veins, tectonized and fairly recrystallized.

Prevailing Applications
Interior and exterior coverings. Interior floors.

Physio-Mecanical Properties
1. Compression breaking load 1150 kg/cm2
2. Compression breaking load after freezing test 960 kg/cm2
3. Bending strength 127 kg/cm2
4. Volumetric weight 2700 kg/m3
5. Water absorption at N.P. conditions 0.2 %
6. Apparent porosity 0.5 %
7. Thermal linear expansion coefficient max. val. 4.3 x 10 -6 perº C
8. Abrasion test 1.9 mm
9. Impact test: minimum fall height 45 cm
Obs. Frost resistance is equal or more than 48 freeze-thawing cycles. The bending strength of this stone is randomly affected by its natural discontinuities (stylolites, etc.)
 
General Description of the Quarry
In the quarry, several tectonized limestone layers occur which, as a whole, are dipping between 40 and 80º N. Average strike of the dominant beds: N 70º E and N 15º W. Main joint system: N 10 to 20º E, 80º W. The availability of commercial size blocks is very dependent of the fractures density. The best ornamental patterns are achieved by cutting the blocks according to the preferential orientation plane (rift plane) or to the grain plane. The quarry shows some reserves and is fairly accessible.
