Examples of Igneous Rocks

The texture of igneous rocks depends on the type of cooling and expulsion to the surface of the magma and can be of glassy texture, fine or coarse grain, pyroclastic, porphyritic or pegmatic.

Igneous rocks are classified depending on whether they form inside the earth’s crust, or outside as intrusive and extrusive respectively.
