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. Granite-typically composed of orthoclase, hornblende, biotite, and quartz-is a felsic rock type. Basalt is mostly olivine, augite, and calcium-rich plagioclase, therefore mafic. slide 3 of 6.
