Descripción
A hard, coarse-grain, black-and-white speckled, granite-like rock composed of plagioclase feldspar mixed with hornblende, biotite, and augite, sometimes with small amounts of orthoclase or quartz. Diorite was valued by the Egyptians and Sumerians for statuary and is presently used in building construction.
