Syenite is a coarse-grained igneous rock primarily composed of feldspar and hornblende, with little to no quartz. It forms from the cooling and solidification of magma beneath the Earth's surface. Syenite is often light-colored and can vary in texture, depending on its mineral composition and the conditions under which it formed. This rock is commonly found in continental crust and is associated with volcanic activity. Syenite is used in construction and as a decorative stone due to its attractive appearance. Its unique mineral content makes it distinct from other igneous rocks, such as granite.
