Types of Natural Stones
Natural stone is a collective name for thousands of different types of stone, found and extracted throughout the world. The aspect and attributes of natural stone are determined by the manner in which the stone was formed: by rivers, by volcanoes and by tectonics.
Each natural stone is unique in its kind because no two places on earth have precisely the same geological composition or precisely the same geological forces. This means that natural stone of the same type can also vary widely.
The very large group of granites consists mainly of magmatic rocks which are formed by the cooling of magma deep in the earth’s crust.
Granites outward appearance is usually dappled in some cases granites are also metamorphic in origin, having been created by the transformation of existing magmatic stone under high pressure. For example, during the development of mountain ranges. These metamorphic granites are typically known for their multi coloring and their unique flamed structure, which makes every individual tile and slab one of a kind.
The sizable group of the marbles contains both metamorphic and sedimentary rocks, all of which are formulated of calciferous particles (calcite).
Marble is a comparatively homogenous and compact natural stone. Since it is relatively easy to work, and also because of its wide variety of different colors, (red, white, pink ect.) it has found many implementations in the building industry: countertops, floors, staircases, fireplaces, etc.
Limestones are sedimentary rocks, generated by the accumulation and compression of fossils and/or stone fragments such as quartz and calcium. The white stones also consist of compressed accumulations of fossils and/or calcium fragments, with a texture which is soft and easily workable. Certain types are suitable for both indoor and outdoor use.
The majority of these limestones cannot be polished and are delivered with lightly honed finish. The best known examples are the French white limestones, but other high quality types are available from Portugal, and Turkey. These types can be used from flooring, fireplaces. Statues, etc.
Quartzite is hard, dense, and extremely abrasion and chemical resistant, quartzite is a metamorphic stone where quartz grains originally belonging to sandstone have recrystalized. Quartzite is becoming popular as a dimension industry. The use of quartzite ads a decorative look in a building and the use of it in construction is growing annually. Quartzite slabs are used to over walls, countertops, as roofing tiles, as flooring, and stair cases to name just a few.
Onyx is a sedimentary stone formed in caves from microcrystalline quartz building up to being stalactites and stalagmites. It is more fragile than other types of stone, velnerable to both chemical and abrasive deterioration, and therefore more suitable for low traffic areas or vertical applications.
Onyx is admired for its translucency and breath taking beauty can be magnified by backlight. With colors ranging from white, to honey colored neutrals, to stunning blues, greens, red, and gold.
Soap stone is a type of metamorphic rock. It is largely composed of the mineral talc and is very rich in magnesium. It is produced by dynamo thermal metamorphism and metasomatism.
Soapstone is chemically inert, non-reactive to harsh chemicals, and extremely dense, even denser than granite. It does not stain, and liquid can’t permeate its surface. Soapstone is soft and scratches easily; the scratches will create a patina on its surface over time which should be expected after everyday wear.
Quartz is the second most abundant mineral in the Earth’s continental crust, after feldspar.
Quartz makes an ideal stone for kitchen countertops. Its non potus surface and unique blend of beauty and easy care makes quartz an exceptional match for any lifestyle. Quartz is scratch resistant and has built in anti microbial protection against bacteria, mold, and mildew buildup.
