Syenite is a variety of felsic igneous rock heavily composed of feldspar. Though formed similarly to granite, the higher aluminum content of syenite indicates a more evolved magma. This sample can be used to great effect in classes regarding igneous petrology and volcanology, and is a good sample to include in identification exercises. Each sample is approximately 1" long and comes in a labeled plastic bag.
