Intrusive Rock Types. Intrusive rocks crystallie from magmas that have been intruded into the earths crust at depths far below the surface. These intrusions are then usually exposed millions or billions of years later through the processes of uplift mountainbuilding and erosion. Other intrusive rocks are discovered through deep
