Classification of Igneous Rocks

As discussed earlier, texture is used to subdivide igneous rocks into two major groups (1) the plutonic rocks, with mineral grain sizes that are visible to the naked eye, and (2) the volcanic rocks, which are usually too fine-grained or glassy for their mineral composition to be observed without the use of a petrographic microscope.
