Volcanic gases at various stages of active volcanism (Shiveluch and Klyuchevskoy Volcanoes, Kamchatka)

This is a summary of the proceedings of the symposium dedicated to the memory of academician A.N. Zavaritskii. It presents volcanic gas data from 1953 through 1958 on two active Kamchatka volcanoes at different stages of their eruptive history. Volcanoes included are Shiveluch (both crater and fumaroles) and Klyuchevskoy's basalt crater named Belyanika. Fumarole gases, condensate vapors and volcanic gases were analyzed in the NaOH-free Basharina-method. Data set includes: acidic content, H2O content and other gases, plus major and trace elements analyses. Trace element analyses do not include actual values measured, they are simply stated as orders of magnitude, which are presented as percentage of the whole (i.e. 0.00n %). Much of the data was simply compared according to its temperatures and therefore dates were omitted from some samples.

本数据集为纪念阿·尼古拉耶维奇·扎瓦里茨基（A.N. Zavaritskii）院士专题研讨会的会议记录摘要。数据集收录了1953年至1958年间，处于不同喷发演化阶段的两座堪察加半岛活火山的火山气体数据。涉及的火山分别为希韦卢奇火山（Shiveluch，涵盖其火山口与喷气孔（fumaroles）区域），以及克柳切夫斯科伊火山的玄武质火山口别利亚尼卡（Belyanika）。本次分析采用无氢氧化钠的巴沙林纳法（Basharina-method），对喷气孔气体、冷凝蒸气与火山气体进行了检测。数据集包含以下内容：酸性组分含量、水分（H₂O）含量及其他气体组分，以及常量与微量元素分析结果。微量元素分析未提供实测具体数值，仅标注了数量级，并以占总组分的百分比形式呈现（即0.00n %）。由于多数数据仅依据温度进行了对比分析，部分样本的采样日期被省略。
