Igneous rocks are rocks that have formed out of magma (molten rock). The two types of igneous rocks most common on Earth are called granite and basalt. Granite is a rock that typically looks pink and white with black specks.Basalt generally just looks black.o summarize, the two types of igneous rocks by chemical composition are felsic and mafic.
