Granite is also igneous rock
- Aug 28, 2018 -

Granite is also a igneous rock, also called acid crystalline plutonic rock. It is the most widely distributed rock in igneous rocks. It consists of feldspar, quartz and mica. The rock is hard and dense. Its composition is mainly silica, accounting for about 65%-75%.

The so-called igneous rock is a rock formed by condensation and crystallization of underground magma or volcanic lava. The content of silica in igneous rocks, the nature of feldspar and its content determine the properties of stone. When the content of silica is more than 65%, it belongs to acidic rock. In this rock, when basic minerals such as feldspar, plagioclase and quartz form crystals, it is a material-like structure, which is called granite.

Granite slabs, sills, counter tops, and outdoor floors are suitable for use. It is best to use dark granite in the counter top. Marble is a metamorphic rock formed by the high temperature and high pressure of the original rock in the earth's crust. The internal force of the earth's crust causes the original rock to undergo qualitative changes, that is, the structure, structure and mineral composition of the original rock change. The new rock formed by the qualitative change is called metamorphic rock.
