摘要：
A brief characteristics of minerals of magmatic rocks is given: pyroxenes, olivine, spinel, garnet, tridymite. Composition of clmopyroxenes indicates two geodynamic regimes in Mesozoic: intraplate (continental crust destruction) and spreading one (partial break of oceanic crust). Garnet from Miocene rhyodacites crystallized within the apical part of magmatic source at high pressure. Presence of tridymite testifies to high, about 1400 degrees C temperatures of acid melts eruption.
