Short summary
The inclusions and exsolution lamellae in rainbow lattice sunstone (RLS) are studied using microscopic observations, chemical analyses and single-crystal X-ray diffraction. Complicated processes producing the aventurescence and adularescence effect in RLS are revealed through the spatial relationship among the inclusions and exsolution lamellae, as well as the unique ordering pattern in the feldspar structures.
