metadata.name: dc.description.abstract
metadata.value: The Eastern Mongolia volcanic area formed in the Late Mesozoic — Early Cenozoic within Central
  Asian Orogenic Belt. The main volcanic events of the area occurred in the Early Cretaceous
  when alkaline basaltic lavas erupted and formed the so-called cover volcanic complex. Geochemical
  and isotope features of the cover volcanic complex allowed researchers to identify the following
  mantle rocks as their source: metasomatized peridotites, eclogites, and pyroxenites. Thermodynamic
  modeling in alphaMELTS program was performed to determine whether the simultaneous
  melting of these rocks with subsequent processes of crystallization differentiation could
  lead to the formation of the studied rocks. The modeling results show that the melting of the most
  enriched with incompatible trace elements peridotites, eclogites, and pyroxenites cannot produce
  the rocks of the cover volcanic complex. At the same time, the mixing of peridotite- and eclogite-
  derived melts corresponds most closely to the mechanism of rock formation. However, Ti, K,
  P, Rb, and Sr enrichment of the studied rocks also requires participation in magma generation
  processes of mantle metasomatic veins enriched with rutile, apatite, phlogopite, and amphibole.
