摘要: We present the first data on composition of plagioclase and quartz-hosted melt inclusions, primary magmatic zoning mineral compositions for Upper Albian tuffites from Bakhchysarai district. The estimated melts corresponds to high potassium rhyolites. measured water content in inclusions reaches 4 wt %. phenocrysts crystallized at temperature within range 820–860°C under pressure not less than 0.1 GPa. district were formed active continental margin environment.
