WebA batholith (from Ancient Greek bathos 'depth', and lithos 'rock') is a large mass of intrusive igneous rock (also called plutonic rock), larger than 100 km 2 (40 sq mi) in area, [1] that forms from cooled magma deep in Earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock types, such as granite, quartz ... WebDue to slow cooling the crystals grow to large size and have approximately same size. The colours and shape depend on the composition of magma and the minerals that form while cooling. The average granite which has grains 3 to 5 millimetres in diameter is a good example. ii.
