易变辉石-
橄榄石的增生边、斜方辉石和易变辉石的反应边，成分均&基质辉石都是变质作用形成的。
Corona on olivine , rim on inverted pigeonite and overgrowth on orthopyroxene , and homogenized matrix pyroxenes are produced by metamorphism .

这些岩石一般都展示了平衡的矿物共生结构，但在镁铁质麻粒岩的单斜辉石中普遍发育斜方辉石（易变辉石）的出溶片晶。
All metamorphic rocks exhibit an equilibrium texture , but exsolution lamellae of orthopyroxene ( pigeonite ) occur in all clinopyroxenes in mafic granulites .
