• Anorthite - Wikipedia

    en.wikipedia.org/wiki/Anorthite Anorthite is the calcium-rich endmember of the plagioclase solid solution series, the other endmember being albite, NaAlSi 3 O 8.Anorthite also refers to plagioclase compositions with more than 90 molecular percent of the anorthite endmember. At 1 atmosphere, anorthite melts at 1553 °C.. Occurrence. Anorthite is a rare compositional variety of plagioclase.

  • Anorthosite - Wikipedia

    en.wikipedia.org/wiki/Anorthosite Mineralogically, labradorite is a compositional term for any calcium-rich plagioclase feldspar containing 50–70 molecular percent anorthite (An 50–70), regardless of whether it shows labradorescence. The mafic mineral in Proterozoic anorthosite may be clinopyroxene, orthopyroxene, olivine, or, more rarely, amphibole.
