    Anorthosite Slide
    Anorthosite Slide £18.00 ex VAT

    Anorthosite is a phaneritic, intrusive igneous rock characterized by a predominance of plagioclase feldspar (90–100%), and a minimal mafic component (0–10%) including Pyroxene, ilmenite, magnetite, and olivine. These thin sections exhibit a rock which has been deformed and as such the once large plagioclase crystals have recrystallized to form much smaller crystals.
