Classification of rocks

Igneous rock: It is formed by the rising magma from inside the earth's crust that invades the earth's crust or erupts out of the earth's surface and condenses. It is also called igneous rock.

Sedimentary rock: It is a geological body formed on the surface and not too deep below the surface. It is a process of transport, deposition and diagenesis of materials produced by weathering, biological processes and certain volcanic processes under normal temperature and pressure conditions. Formed by a series of geological processes.

Metamorphic rock: It is rock produced due to changes in rock structure caused by the internal forces of the earth.

Common rocks: granite, sandstone, shale, limestone, marble, etc.

granite

Granite is an igneous rock, formed by the eruption and cooling crystallization of underground magma, as well as granitic metamorphic rocks. Has visible crystal structure and texture. It consists of feldspars (usually potassium feldspar and feldspar) and quartz, mixed with small amounts of mica (biotite or muscovite) and trace minerals. Normally, granite is slightly white or gray, with a mottled appearance due to the mixture of dark crystals, and the addition of potassium feldspar makes it red or flesh-colored.

Marble

Marble is formed from sedimentary rocks and metamorphic rocks of sedimentary rocks. It is a metamorphic rock formed by the recrystallization of limestone and is usually accompanied by the texture of biological remains.
