ZIRCON OF METAMORPHIC ROCKS. FEATURES OF CRYSTAL MORPHOLOGY, CHEMISM AND ZONAL STRUCTURE

The article summarizes information of the crystal morphological features of zircon from metamorphic rocks, its internal structure, crystal matrix chemism, and rare earth element distribution. These data make it possible to reveal discriminant features of zircon as depend on the origin of the substance crystallized and the conditions of its transformation during metamorphism. For a reliable assessment of the content of elements in zircon, it is necessary to perform a set of analytical methods, since the concentration of impurities varies significantly even in samples from the same rock. This makes it possible to determine the range of variations and to evaluate the dynamics of the distribution of elements in zircons from metamorphic rocks of various genesis.
