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. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. Phyllite is available in black to grey, light greenish grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phyllite is white. Get to know more about Phyllite rock and characteristics of Phyllite rock in the next sections.
