Potencial ornamental del plutón de Sierra Bermeja (Badajoz): evaluación de su canterabilidad

Abstract

The Sierra Bermeja pluton is mainly composed of three peraluminous granitic facies: Cornalvo, Moro and Raposeras. The three facies show four main joint systems, two of them developed at regional scale oriented N5/900 and N120/90°, and the other two, related to the cooling process of the pluton, oriented N55/900 and NT45/90. The Moro granite shows the greater potential as dimension stone, with good quarriability and interesting aesthetic characteristics. The Raposeras granite has aesthetic interest but the closely spaced jointing may imply quarriability problems. The aesthetic characteristics of the Cornalvo facies are not fashionable in the ornamental industry and also this facies has specific difficulties to obtain homogeneous blocks
