Some mineralogical and chemical properties of volcanic glasses were investigated in relation to the rock types of their volcanic ashes. Almost all of the volcanic glasses contained in rhyolitic, dacitic, and andesitic volanic ashes showed refractive indices ranging from 1.49 to 1.51,and were rhyolitic in chemical composition. The amounts of crystalline minerals were largest in andesitic volcanic ashes. The mean mineral composition of four typical andesitic pumices was as follows : volcanic glass, 53.4% ; plagioclase, 29.8% ; two pyroxenes, 13.3% ; and titanomagnetite, 3.5%. On the other hand, rhyolitic and basaltic volcanic ashes contained small amounts of crystalline minerals.
