Orthogneiss designates a gneiss derived from an igneous rockand paragneiss is one from a sedimentary rock. It is a black mica with perfect cleavage and a vitreous luster on the cleavage faces. It usually is prominent from schist by its foliation and schistosity; displays a properly-advanced foliation and a poorly advanced schistosity and cleavage. Not all gneiss rocks have detectable banding. Phonolite is the fine-grained extrusive equivalent.

  • Metamorphic Gneiss has many uses as a building material such as flooring, ornamental stones, gravestones, facing stones on buildings and work surfaces. Gneiss is a foliated metamorphic rock in which the coarse mineral grains have for these minerals, examples of which include "garnet gneiss" and "biotite gneiss. This allows contractors to use gneiss as a crushed stone in road construction. The uses and properties of the mineral Biotite.

    Ground mica is used as a filler and extender in paints, as an additive to drilling muds, as an inert filler and mold-release agent in rubber products, and as a non-stick surface coating on asphalt shingles and rolled roofing. It is one of the features that helps differentiate gneiss from other foliated rocks.

    Some also contain larger crystals imbedded in the rock matrix, most frequently garnet, topaz, and beryl minerals. In addition to the Outer Hebrides, they form basement deposits on the Scottish mainland west of the Moine Thrust and on the islands of Coll and Tiree.

    Some peridotite is mined for ornamental stone. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct foliation.

    These minerals generally cannot be distinguished from one another without laboratory analysis. Another cause of banding is "metamorphic differentiation", which separates different materials into different layers through chemical reactions, a process not fully understood.

    Gneiss usually does not break up alongside planes of weak point like maximum other metamorphic rocks. Peridotite that has been hydrated at low temperatures forms serpentinite, which may include chrysotile asbestos a form of serpentine and talc.

    1. Gneissic rocks are usually medium- to coarse- foliated ; they are largely recrystallized but do not carry large quantities of micaschlorite or other platy minerals.

    2. How Is Mica Formed? Gneiss rocks exhibit a unique form of foliation known as gneissic banding, which are thicker bands of foliation than most metamorphic rocks display.
