Syenite is an uncommon, coarse-grained, intrusive igneous rock. It has the same general composition as granite, but the quartz component is either absent or present in relatively small amounts (less than five percent). The predominant minerals in syenite belong to the feldspar group. The different varieties of syenite are named on the basis of additional minerals in the rock—for example, hornblende syenite and mica syenite. Syenites are occasionally used as building stones.
