Also called Corsite or Napoleonite, orbicular diorite has characteristic spherical structures called orbicules. Its chemical composition is intermediate between a diorite and a gabbro. The light-colored minerals are anorthite and bytownite-type calcic plagioclase feldspars, while the dark minerals are hornblende-type amphiboles and pyroxenes. Orbicular diorite is known to have been used to make the tomb of Napoleon I at Les Invalides and the Medici funeral chapel in Florence.
