Question:   What is syenite used for?

Answer:   Syenite is an igneous rock that is usually gray, pink or violet in color. Because it is an intrusive rock, you can see small to medium-sized mineral crystals in the rock which include mostly feldspars and hornblende with smaller amounts of minerals such as pyroxene, mica, quartz and magnetite.  Nice deposits of syenite are often found in Egypt, Italy, Germany, Norway, and United States. Syenite does not have too many uses other than as polished slab for construction in buildings.
