Syenite | Igneous, Intrusive, Plutonic | Britannica
Syenite, any of a class of intrusive igneous rocks essentially composed of an alkali feldspar and a ferromagnesian mineral. A special group of alkali syenites is characterized by the presence of a feldspathoid mineral such as nepheline, leucite, cancrinite, or sodalite (see nepheline syenite).

Syenite: Identification, Pictures, & Info for Rockhounds
Syenite is a light-colored, coarse-grained igneous rock with crystals that are visible to the naked eye. It is commonly pinkish due to its high alkali feldspar content, with little quartz. Intermixed dark, mafic minerals often give syenite a 'salt and pepper' look. It lacks features like layering, banding, or fossils.
