  • Pohorje granodiorite - one of the most significant Slovenian natural stones [Elektronski vir]
    Dolenec, Sabina ...
    We describe the petrographic and mechanical characteristics of granodiorite from the Pohorje Mountains (NE Slovenia) and its use as a natural stone. This stone, which is a calc-alkaline igneous rock ... of the Miocene age (18.7 Ma), is characterized by its grey colour and thick white aplite-pegmatite veins. It mainly consists of plagioclase, quartz, and K-feldspar, which are light-coloured constituents, as well as biotite and a small amount of hornblende, which are dark-coloured minerals. This granodiorite is considered the highest quality natural stone in Slovenia. It is characterised by high density, low water absorption, and low open porosity, so that it exhibits highfrost and salt resistance, as well as a high compressive strength and a very high flexural strength. It is widely recognised throughout Slovenia for its durability and its decorative white veins, with the consequence that it isthe most frequently used natural stone in Slovenia today. It is mainly used as paving and cladding material for residential buildings, churches, and otherstructures, in addition to public areas where it adds special character to many of the larger towns and cities. Several important buildings are also decorated with this stone including the Slovenian Parliament, the Republic Square business complex, and the Faculty of Law of the University of Ljubljana, all of which are located in Ljubljana, some having been declared cultural monuments of national importance. Since 1940, Pohorje granodiorite has also been widely used by sculptors for various monuments and fountains.
