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 Ijolite Uses. We have provided you with all information about Ijolite rock here. Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite. Ijolite 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 Ijolite is white. Get to know more about Ijolite rock and characteristics of Ijolite rock in the next sections.
