Helium isotopes in geothermal fluids reveal off-rift mantle plume degassing and localized seismicity-induced processes in North Iceland

This dataset accompanies the manuscript "Helium isotopes in geothermal fluids reveal off-rift mantle plume degassing and localized seismicity-induced processes in North Iceland". It contains analytical data on hydrogen, helium, carbon, oxygen, and sulfur isotopes of geothermal fluids from North Iceland (Table 1). Major elements are given in Table S1 and time series data of helium isotopes in Table S2. Data are provided in a Word file.

本数据集配套学术论文《冰岛北部地热流体中的氦同位素揭示裂谷外的地幔柱（mantle plume）脱气（degassing）与局地地震活动诱发过程》，包含采自冰岛北部的地热流体（geothermal fluids）的氢、氦、碳、氧及硫同位素分析数据（表1）。主量元素数据详见补充表S1，氦同位素（helium isotopes）时间序列数据详见补充表S2。所有数据以Word文件格式提供。
