The Krastal marble occurs in the Millstättersee Mountains at its east end, in Carinthia (Austria) in the Krastal , a valley cut. In the middle of the Krastal there are quarries that were already used by the Romans. This marble was used in construction for centuries: six Roman pointed irons were found in the so-called Franz quarry, which are now exhibited in the Landesmuseum Klagenfurt.

Rock description and quarries

The Krastaler marble is a coarse-grained gray marble with a grain size of 3 to 5 millimeters. This natural stone contains phlogopite and lime and magnesia silicates . Krastal marble is clearly banded and is embedded in slate gneiss. This marble becomes lighter at the edge of the deposit. The corresponding reaction minerals are located at the storage limits of the marble on gneiss , pegmatite and amphibolite .

Quarries were operated by Della Schiava , Adami , Vogler , Fantoni , Leitner and Franz until the early 1950s . The Franz quarry was one of the largest and in the 1950s it was 90 meters long, 40 meters high and 30 meters deep on its hillside.

use

The Krastal marble is extremely weatherproof. Signs of weathering show up only in a slight roughening of the surface, which does not spread any further. The strength of this marble is so high that it was previously used as railway ballast.

In this deposit, the gaps are large, which is why rough blocks measuring 3.00 × 2.00 × 0.75 meters, slabs up to 8 m² and columns up to 3 meters in length can be extracted. It was used for monuments and tombs, wells and, above all, as stone for buildings.
