Lithology - Wikipedia

In igneous and metamorphic rocks, grain size is a measure of the sizes of the crystals in the rock. In igneous rock, this is used to determine the rate at which the material cooled: large crystals typically indicate intrusive igneous rock, while small crystals indicate that the rock was extrusive. Metamorphism of rock composed of mostly a single mineral, such as quartzite or marble, may ...

However, in a strict definition gneisses are metamorphic rocks, which means that the light bands form through recrystallization alone; the light layers did not form by cooling from a melt. Distinguishing between gneisses and migmatites can be slightly challenging to do in the field. The two rock types are certainly relatives, so to speak.
