Some mineralogical data on genesis of magmas of the Carpathian region
A brief characteristics of minerals of magmatic rocks is given: pyroxenes, olivine, spinel, garnet, tridymite. Composition of clinopyroxenes indicates two geodynamic regimes in Mesozoic: intraplate (continental crust destruction) and spreading one (partial break of oceanic crust). Garnet from Miocen...

Composition of clinopyroxenes 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°С temperatures of acid melts eruption. |
