Abstract (in english)
   The presence of some macroscopic signs (dark "chilled" fine-grained margins, parallel arrangement of minerals to the contacts) is the evidence of comagmatic evolution of the enclaves and the host rocks. Acicular crystals of apatite are indicative of rapid crystallization of the enclaves liquid. Plagioclase xenocrysts support a concept of mutual mechanical exchanges. Close geochemical trends of the enclaves and the host rocks are most likely caused by an intensive chemical interactions.
