Metamorphic rock is made by heat and pressure on layers of sediments and in creates. What is an igneous rock. Igneous rocks are rocks that are formed by the cooling and solidification of magma or lava.

Typically granite makes up large parts of all the continents. It forms from the slow crystallization of magma below earth s surface. For countertops the granite blocks are cut into granite slabs. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral.

Outcrops of granite tend to form tors domes or bornhardts and rounded massifs. They include not only lava spewed from volcanoes but also rocks like granite which are formed by magma that solidifies far underground.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Learn more about the properties and uses of granite in this article. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. A rock with a similar composition and appearance as granite gneiss can form through long and intense metamorphism of sedimentary paragneiss or igneous rocks orthogneiss.

Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Granite is a igneous rock that was formed from magma cooling and hardening.

Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands. Much of it was intruded during the precambrian age.
