I am stymied to explain the stratigraphic variations found in some large-volume silicic pyroclastic deposits such as the Bishop Tuff, California. I use melt (now glass) inclusions in quartz phenocrysts to assess the depth and amount of exsolved gas in the preeruptive magma.
I have used melt inclusions to assess the roles of volatiles and of magma mixing in a wide range of magmas.
