  • Plagioclase: The mineral Plagioclase information and pictures

    The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium. Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and Bytownite. The acclaimed Dana's System of Mineralogy lists the intermediary members as individual minerals, whereas ...

  • Feldspar - Wikipedia

    Feldspars (K Al Si 3 O 8 – Na Al Si 3 O 8 – Ca Al 2 Si 2 O 8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar …

    What is Quartzite? Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz.It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism.. Metamorphism recrystallizes the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength.
