| 英文摘要 | Carbon was carried into the Earth's interior by plate subduction, and returned to the exogenic environment mainly by volcanism, which constitute the main process of deep carbon cycles in the Earth and drive the long-term (similar to Myr) climate change. Cenozoic intraplate volcanism in NE China is deemed to be derived from deep subducted Pacific slab in the mantle transition zone (MTZ), along with large quantities of crustal carbonates, which makes the upper mantle beneath NE China a huge carbon reservoir in Cenozoic era, whose activity and release would have a significant impact on global climate and environmental change. Nevertheless, the total output of volcanic carbon, its origin and evolution process remain controversial. Studies were performed in Cenozoic volcanic fields of Changbai volcanic field (CVF), Wudalianchi volcanic field (WVF) and Aershan volcanic field (AVE) in NE China to better constrain this issue. The fluxes of soil CO2 emissions from Cenozoic volcanic fields in NE China are between 9.6g . m(-2) . d(-1) and 41.2g . m(-2) . d(-1), and the total flux of volcanic CO2 is reviewed and recalculated to be 2.1Mt per year, about 0.94Mt from the CVF and 1.2Mt from WVF. Chemical compositions and C-He isotopes indicate that CO2-riched gases in CBV and WVF might originate from deeply subducted Pacific slab beneath NE China. However, volcanic gases from WVF show more proportions of crustal components than that in CVF. Bubble gases from hot springs in AVF exhibit enrichment in N-2 (> 95%) and remarkable contribution from crustal nitrogen-rich organic components, as indicated by relatively heavier delta N-15(N2) values (1. 3 parts per thousand similar to 1.9 parts per thousand),low He-3/He-4 ratios (0.14 similar to 0.18R(A)) and light delta C-13(CO2) values (-13.7 parts per thousand similar to 6.2 parts per thousand), which reveals that volcanic gases in AVF may not be prominently influenced by the recycled materials from deeply subducted Pacific slab. We suggest that the primordial gases in AVF are contaminated by large quentities of crustal materials during its long time retention in the groundwater systems. |
