Information about Phyllite

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 Phyllite Uses. We have provided you with all information about Phyllite rock here.
