  1. oligoclasenoun

    A plagioclase feldspar, the second member of the Albite-Anorthite solid solution series. Primarily found as small crystals in impure marble. Oligoclase contains a small amount of calcium substituting for some of the sodium in its formula. Oligoclase with reddish-golden inclusions found in Norway and Canada is called sunstone.

Wikipedia

  1. Oligoclase

    Oligoclase is a rock-forming mineral belonging to the plagioclase feldspars. In chemical composition and in its crystallographic and physical characters it is intermediate between albite (NaAlSi3O8) and anorthite (CaAl2Si2O8). The albite:anorthite molar ratio of oligoclase ranges from 90:10 to 70:30. Oligoclase is a high sodium feldspar crystallizing in the triclinic system. The Mohs hardness is 6 to 6.5 and the specific gravity is 2.64 to 2.66. The refractive indices are: nα=1.533–1.543, nβ=1.537–1.548, and nγ=1.542–1.552. In color it is usually white, with shades of grey, green, or red.Oligoclase is a common mineral in the more silica-rich varieties of igneous rock and in many metamorphic rocks.

  1. oligoclase

    Oligoclase is a type of plagioclase feldspar, which is a group of rock-forming tectosilicate minerals that make up as much as 60% of the Earth's crust. It is relatively common and has a hardness of around 6-6.5 on the Mohs scale. Oligoclase is typically white or gray and is often used in the manufacture of glass and ceramics. It has a triclinic crystal system and may contain trace amounts of other elements such as calcium, sodium, and aluminum.
