摘要：

On the basis of the study of volcanic products during 1199-1200AD eruption of Baitou Mountain (Baitoushan), the released volatile content was estimated by comparing Cl, F, S, H2O concentrations of undegassed glass inclusions with those of degassed matrix glasses. The calculations show that volatile yields, released from the melt, are 109.88 X 10(6) ton of HCl, 196.80 X 10(6) ton of HF, 1477.84 X 10(6) ton of H2O, 23.14X 10(6) ton Of SO2, which could have formed 35.43 X 10(6) ton of H2SO4 aerosol in the atmosphere. They could have substantial effect on paleoclimate and paleo-environment.
