Information about Syenite

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Syenite Uses. We have provided you with all information about Syenite rock here. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. Syenite is available in brown, buff, cream, green, grey, pink, white colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Syenite is white.
