Summary:The description of morphology and internal structure of zircon crystals from the rocks of different magmatic phases of the Novoukrainka pluton, distinguished by geological observations is given: gabbroids and monzonitoides, composing the xenolithes among trachytoid granites (first phase), garnet-biotite and hypersthene-bearing trachytoid granites (the second phase), as well veined subalkaline porphyry and medium-grained, equigranular granites (third phase). It is concluded that as to mineralogical features the zircon crystals from gabbroids have the magmatic genesis. Since zircon crystals from monzonitoids, which were related to the first phase, according to geological observations as well as the zircon crystals from trachytoid granites of the second phase, contain heterogeneous nuclei of substratum zircons, it is supposed, that monzonitoids and trachytoid granites are palingenetic-anatexite formations. Rocks of their substratum are most probably the metamorphic rocks of Ingul-Inguletz series. Monazites of the granitoids have the magmatic genesis, but in contrast to zircon, the monazite crystals were generated as a result of certain endogenic process.
