Synonyms: Landøy Stone

Location: Black Beauty granite is quarried on the island of Værlandet, west coast of Norway. It has a small capacity of approximately 400-500 m3 per annum with a wide variation of block sizes.

Description: Black Beauty granite is a natural, nearly black, sedimentary volcanic breccia with triangular clasts in a fine-grained, grey groundmass. A sedimentary rock found at the boundary between greenstone and conglomerate. This stone internationally may be nominated as a granite but in the area of application of the European Standard we are awaiting clarification.

The veining and colour varies considerably and a small sample of Black Beauty granite may not be representative of the whole slab therefore swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Black Beauty granite is frost free and probably polish constant.

Mineral Composition: In the greenstone fragments: 45% Chlorite, 35% Amphibole, 10% Feldspar, 3% Muscovite, 2% Hematite, 2% Epidote

Mineral Composition: In the intermediary deposit: 45% Quartz and Feldspar, 14% Chlorite, 15% Carbonate, 10% Epidote, 10% Amphibole, 3% Hematite, 2% Muscovite, <1% Biotite, Titanite, Zircon

Granite: Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark grey or even black, depending on their chemistry and mineralogy.

Volcanic Breccia: A rock composed of angular fragments embedded in a fine-grained matrix. Breccias form from explosive volcanic ejections, the compaction of talus, or plate tectonic processes. Breccias are different from conglomerates in that the fragments they contain are angular instead of rounded.
