metadata.name: dc.description.abstract
metadata.value: This article presents new and summaries of previously published geochemical and geochronological
  data on rocks of the Potudan pluton and host granitoids of the Kholhol-Repyevka batholith
  in the central part of the Don Terrane (DT) of Volga-Don orogen. The host granitoids
  of the Khokhol-Repyevka batholith are assigned to the Pavlovsk granitoid complex, which is
  widespread in the southern part of the DT. The studied Potudan pluton rocks are differentiated
  from quartz monzogabbro to granodiorites. They are ferroan, meta-aluminous, and the
  K2O content displays their relationship to the shoshonite series. For the intrusive complexes
  of the Don terrane, it is assumed that an enriched heterogeneous source with high contents
  of alkalis, large-scale lithophile elements and light rare earth elements is involved, the mantle
  component is confirmed by increased of MgO, Cr, Ni, Ti, as well as high Sr/Y ratios, (La/Yb)N,
  (Dy/Yb)N, indicating the deep origin of magmas. The source heterogeneity could have been
  provided by subduction events about 2.1 Ga. The U-Pb zircon age of crystallization of the
  Potudan pluton rocks (using the SHRIMP II instrument) is 2061 ± 5.4 Ma and corresponds
  to the postcollision event in the junction zone of the Sarmatiа and Volga-Uralia segments of
  the East European Craton. Association of Potudan rocks with Pavlovsk granitoids in time and
  space and also morphological features of zircon from various types of rock suites prove the
  effect of hybridization process during crystallization of the composite batholith. The new data
  make it possible to expand our understanding of the evolution of crust of the Don Terrane and
  geodynamic regims of its formation.
