Catalogue of Galician Granites
This is a compilation of all the granite varieties extracted as ornamental rock currently in Galicia.
An informative tool designed to identify and value the Galician natural resources and very useful for professionals who work with natural stone.
What is natural stone?
Natural stone or ornamental rock are the natural rocks that are extracted from nature in blocks and, after some processes of cutting, sizing and surface treatment, are suitable for use as building materials and for ornamental purposes.
What is granite?
Geologically, granite is a plutonic igneous rock of acid composition with a content in quartz between 20-60%, and feldspars (alkaline and plagioclase) as the other two main minerals also with defined characteristics.
The granite from Galicia
Galicia is located within the Iberian Massif with 3 of its zones, from east to west: West Asturian-León Zone, Central-Iberian Zone and Galicia-Trás-os-Montes Zone.
The granitic bodies adapt with elongated forms to these zones following the variscan regional formations, except post-kinematic intrusions, which form sub-circular or elliptical bodies on the surface
Galicia produces a wide variety of granites, ideal for any architectural or interior design application.
The textures of Galician granite
The combination of the different shades for each granite variety and the multiple surface finishes provide us with a wide range of textures.
