Rare examples of this rock type include komatiites and carbonatites. Observation of fabrics in rocks of this type led to the development of Bowen's Reaction Series. Porphyritic, graphic, or trachytic textures are common to rocks of this type, which are classified as felsic when rich in quartzes or feldspars. They are classified as intrusive when they solidify at depth and extrusive when they are formed on the surface. For 10 points, name this rock type, an example of which is granite, encompassi
