- Abstract:
-
We report here novel field spectroscopic measurements of the proportions of H2O, CO2, CO and SO2 in gas emissions from Oldoinyo Lengai, the world's unique, active carbonatite volcano. We found that CO2 constitutes <40mol% of emissions from a lava lake, and 25mol% from a cooler fumarole vent. These results suggest that H2O is the predominant gas phase rather than CO2, as reported in previous studies based on conventional sampling (Trans. Am. Geophys. Union 69 (1998) 1466; J. Geophys. Res. 1...
