Assessing the deep carbon release in an active volcanic field using hydrochemistry, δ13CDIC and Δ14CDIC

Volcanic activities have great implications on geological carbon cycle, and ascertaining the deep carbon contribution in earth surface that run along the volcanic edifices is important to understand the relationship between earth degassing and global climate change. This study reports analytical results of major dissolved ions, stable carbon isotope (δ13CDIC) and radiocarbon (Δ14CDIC) of dissolved inorganic carbon (DIC) of rivers, cold springs and hot springs from Changbaishan volcanic area, Northeast China. , ,火山活动对地质碳循环具有重要意义，明确沿火山构造分布的地球表层深部碳贡献，对于理解地球脱气与全球气候变化之间的关联至关重要。本研究报道了中国东北长白山火山区内河流、冷泉及热泉中溶解无机碳（Dissolved Inorganic Carbon，DIC）的主要溶解离子、稳定碳同位素（δ¹³C_DIC）以及放射性碳（Δ¹⁴C_DIC）的分析结果。
