Is granite made from magma.

Granite is an igneous rock predominantly consisting of quartz and feldspar. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. Granite is usually composed of feldspar quartz amphiboles and mica. Granitic or rhyolitic magmas and andesitic magmas are generated at convergent plate boundaries where the oceanic lithosphere the outer layer of earth composed of the crust and upper mantle is subducted so that its edge is positioned below the edge of the continental plate or.

Granite is formed when magma that is under the surface of the earth slowly crystallizes. The colours and structures of granite differ depending on the types of molten rock and the way the crystals form when cooled. It is made up predominantly of minerals such as feldspar mica and quartz. The combination of the two must make up at least 55 percent of the rock.

These minerals and their variation in abundance and alteration give granite the numerous colors and textures we see in granite countertops. Granite is an igneous rock made up of primarily quartz feldspar micas amphiboles and a mixture of additional trace minerals.
