Natural Stone Application

Igneous Rocks Application

Igneous rocks make up 90 to 95% of the volume and thickness of 16 km (from the top) of the earth’s crust. Igneous rocks play a very important role in geology because their mineral and chemical properties tell us a lot about the mantle composition, where the igneous rocks were extracted from, and the temperature and pressure conditions that allowed them to form this way, or otherwise. A pre-existing rock that has been melted.

Igneous rocks are divided into three categories, and each category rocks have different uses, but in general, the igneous rocks use include:

• cosmetics Production
• Making flooring and floor tiles
• In road construction and bridge construction
• In wall covering, the building interior and exterior
• Making all abrasive stones kinds such as foot stones
• Making all sculptures kinds
• Dams
• Used in stairs and corridors
• Use in railway construction
• Crusher
• Iranian natural stones

Sedimentary Rocks Application

Sedimentary rocks cover almost the continents entire surface, but all crustal rocks generally comprise 8%. Sedimentary rocks are just a thin layer on the crust. The sedimentary rocks study and this thin crust on earth gives us a lot of information.

Its uses include the following:

• Suitable for facade
• Used in agriculture to prevent weeds
• Use in paper making
• Used on the floor
• Wall covering
• Pool side

Metamorphic Rocks Application

Metamorphic rocks are rocks that are formed almost from the previous rocks deformation  due to changes in physical (pressure-temperature) or chemical conditions and in a solid state. The metamorphic phenomenon is interpreted as the one or a set crystallized disappearance minerals in a rock. These changes may occur on sedimentary rocks formed in surface conditions or in igneous rocks crystallized from magma or even in metamorphic rocks.

Metamorphic use stones is as follows.

• Dams
• Stairway
• Making ornaments
• Building facades
• Construction
• Sculpture
• Automobile manufacturing and
