For instance, the spherical shape can be used to approximate the rhombic dodecahedron crystals of garnet in metamorphic rocks as well as the prismatic shape is suitable for approximation of tabular crystals of plagioclase in basalts.
Garnet from the Puiva clefts looks identical to that from the Dodo deposit - transparent red rhombic dodecahedrons to 7 mm - but differs chemically.
Various [Ag.sub.3]P[O.sub.4] nanostructures including spherical morphology [33, 34], rhombic dodecahedrons [30], concave trisoctahedrons [37], cubes [26, 30], and tetrapods [38] with controlling particle size [39] have been designed and synthesized to further improve or optimize the photocatalytic properties.
