In this article, we will discuss natural stone applications on a technical level. 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 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:
Sedimentary rocks cover almost the continents entire surface, but all crustal rocks generally comprise 8% of the earth crust. 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:
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.
