Abstract

Infrared spectroscopic (H ₂ O and CO ₂ ) and electron microprobe (Cl) analyses of glass inclusions in Plinian and ash-flow quartz phenocrysts from the Bishop Tuff reveal the preeruption concentrations of volatiles in separate parts of the body of magma. There is an inverse relation between H ₂ O and CO ₂ that can be explained 1) by closed-system, gas-saturated crystallization of parent magma to yield Plinian magma + (lost) crystals or 2) by the rise of CO ₂ -rich bubbles through water-rich magma. Our estimated pressures of gas-saturation range from about 1.6kbar (Plinian) to 2.3kbar (ash flow) and accord with geologic evidence for 3km of magma withdrawal and caldera subsidence. -Authors
