长白山天池火山全新世大喷发挥发性气体释放量的分析和估算

Analysis and estimate of volatile in Changbaishan Tianchi volcano great eruption in Holocene epoch.

火山喷发是地球上一种壮观的自然景象 ,火山喷发的同时一般都喷出气体 ,火山爆炸式喷发时巨量的气体被喷入空中 ,对全球气候造成较大影响。长白山天池火山于全新世发生过两次较大的爆炸式喷发 ,根据本文的分析和估算 ,后一次即天池火山公元 1199～ 12 0 1年的那次大喷发 ,逃逸到空中的挥发气体含量分别为 :CO2 约 (0 .31～ 1.5 6 )× 10 8t,S(主要是 H2 S和 SO2 )约 1.96× 10 7t,F2 约 7.86× 10 6 t,Cl2 约 (0 .78～ 6 .2 4)× 10 7t。

Volcano eruptions are magnificent landscape on the earth, meanwhile they should erupt gases. When volcano explosively erupted, the giant quantity of gases were erupted to the air and effected the global climate. Changbaishan Tianchi volcano had two great explosive eruptions in modern history, the latter one erupted in 1199~1201 AD, producing volatile including CO2 (0.31-1.56)*108t, S 1.96*107t, F2 7.86*106t, Cl2 (0.78-6.24)*107t, and had made important influence on the global climate.
