Information about Adakite

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 Adakite Uses. We have provided you with all information about Adakite rock here. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. Adakite is available in black, brown, light to dark grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adakite is bluish black. Get to know more about Adakite rock and characteristics of Adakite rock in the next sections.
