These rocks form crystals because of their slow cooling and some examples are basalt and granite.
These entities can be grouped with the TAS classification system based on their alkali composition, and if their individual grains are distinguishable, they are phaneritic. The hypabyssal type of these rocks is formed between a pluton. Their silicon content classifies them as either (*) mafic or felsic, and a large clump of them known as basoliths can be surrounded by an intrusive mass, exemplified by Devil's Tower. These rocks form crystals because of their slow cooling and some examples are basalt and granite. For 10 points, name these rocks formed from cooled magma.
