- W2318866476 abstract "Large volumes of dacitic and rhyolitic pyroclastic flows were erupted about 4 to 1 m. y. ago along the volcanic front in northeastern Japan, before the basaltic to andesitic volcanoes formed. These rocks are usually highly porphyritic, bearing 20-47 vol. % of quartz, plagioclase, pyroxenes, hornblende and iron oxides as phenocrysts. The biotite rhyolites lack pyroxenes but contain sanidine, cummingtonite and biotite in addition to above mineral assemblage. The mineral thermometries suggest that the magma temperatures of these rocks are within the range of 980 ?? 910°C, similar to those of Quaternary dacitic rocks in the same region. Major and incompatible trace-element abundances in the dacitic and rhyolitic pyroclastic flows vary smoothly with increasing SiO2 or advancing fractionation and follow a typical calc-alkaline salic andesite and dacite trend. The dacitic and rhyolitic magmas are probably late differentiation products after a high degree of fractional crystallization of typical island-arc calc-alkaline mafic magma derived from upper mantle. They probably were not produced by partial melting of the gabbroic lower crust." @default.
