Abstract
In the work the composition of nearly 70 naturally-quenched olivine-, plagioclase-, clinopyroxene and orthopyroxene-hosted melt inclusions from tephra of Simushir island (Central Kuriles) was studied. For the inclusions measurements of main petrogenic components, H2O, S and Cl were conducted. Reconstructed melts contain 48,6-78,4 wt.% SiO2, 0,3-8,26 wt.% MgO and 0,12-1,72 wt.% K2O. Content of S and Cl in melts changes naturally with increasing of SiO2: S - from 0,14 to 0,02 wt.% and Cl - from 0,05 to 0,28 wt.%. Water content in parental melts is 4,2-4,5 wt.%.
