Labradorite granite

How to POLISH STONES with sandpaper and water

It is an intermediate member of the solid solution series of plagioclase, the ends of which are albite (sodium plagioclase) and anorthite (calcium plagioclase). For this reason, it is sometimes considered as a variety of anorthite.

Labradorite is named after its first location, the Labrador Peninsula (Canada).[1] It was discovered on its coast in 1770 by the Czech missionary Father Adolf. It was first described in 1896 in Max Bauer’s Edelsteinkunde (Gemology) book.

It appears in the form of well-formed crystals, elongated or tubular in habit, implanted or twinned: polysynthetic type twins are very frequent, easily recognizable thanks to the presence of fine striations, which are governed by the laws of albite and pericline, which differentiates them from potassium feldspars such as orthoclase.

Apart from the collecting interest, labradorite has industrial applications in the manufacture of ceramics, refractory materials and enamels, as well as being used cut into large slabs in the construction of buildings as ornamental wall cladding.


The province of Buenos Aires has important deposits and reserves of industrial minerals and application rocks and has historically provided a large amount of materials to the construction industry. Within the application rocks, the term “ornamental rocks” refers to stone materials used for cladding or building ornamentation.

The locality of Sierra Chica, in the district of Olavarría, is a classic district dedicated to the exploitation of ornamental and crushed granitic stone. At present, the extraction of blocks of ornamental materials is restricted to the granite outcrops near this locality, where there are six quarries dedicated to the exploitation of granite in its varieties called “Rojo Sierra Chica” and “Labradorita”, with a production of commercial blocks of about 4,000 m3 per year.

These rocks are part of the igneous-metamorphic basement of the Tandilia System called “Buenos Aires Complex”. They are reddish to pinkish colored granites (Rojo Sierra Chica variety) or brown to greenish brown (Labradorite variety) with a coarse granular texture. The Rojo Sierra Chica granite has a mineral fashion of: 30% quartz, 35% microcline, 10% biotite, 5% amphibole and opaque minerals and 20% chlorite, sericite and clays. The Labradorite, on the other hand, has a mode of 32% quartz, 40% microcline and orthoclase, 15% biotite, 5% amphibole and opaque minerals and 8% chlorite, sericite and clays.

Natural stone cutting

Dekton is a surface with high resistance to scratching. It does not scratch with household utensils. However, we recommend the use of cutting boards to protect household utensils.

Due to its low porosity, the new Dekton surface is highly resistant to occasional household stains and chemical agents. It also has a very good resistance to high temperatures without affecting its aesthetics and properties.
