Information about Minette

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 Minette Uses. We have provided you with all information about Minette rock here. Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Minette is white. Get to know more about Minette rock and characteristics of Minette rock in the next sections.
