Supplementary Data for "Melt inclusions reveal massive carbon dioxide emissions from continental intraplate volcanism" by Buso et al. 2025

This folder contains Supplementary Data Tables (TS1 to TS6) and four raw Raman spectra from the article “<b>Melt inclusions reveal massive carbon dioxide emissions from continental intraplate volcanism</b>” by Buso et al. (2025) published in Communications Earth &amp; Environments.The supplementary data tables are: Supplementary Data Table 1. Database of CO₂ contents in primary magmas and melt inclusions from intraplate settings.Supplementary Data Table 2. Glass compositions measured in unheated melt inclusions from Bas-Vivarais: raw EPMA data.Supplementary Data Table 3. Glass compositions measured in unheated melt inclusions from Bas-Vivarais, corrected from PEC with MIMiC.Supplementary Data Table 4. Glass compositions measured in melt inclusions from Bas-Vivarais after homogenization at high pressure: raw EPMA data.Supplementary Data Table 5. Glass compositions measured in melt inclusions from Bas-Vivarais after homogenization at high pressure, corrected from PEC/PED with MIMiC.Supplementary Data Table 6. Amount of CO₂ emitted per km³ of erupted magma for a selection of recent and historical eruptions.The list of the references cited in these files are available in the Supplementary Information file. <br>The raw Raman spectra (txt files) were used to create the Figure 2 of the article. The spectra are related to two samples: Ja2-Plot5-Grain4 and HOP11a-MIa, which are unhomogenized and homogenized inclusions, respectively, from the Bas-Vivarais volcanic province (French Massif Central). Two spectra measured in olivine next to these two inclusions are also included in this folder and can be used to correct the spectra for olivine contamination.These spectra have been processed following the method explained in the paper to obtain the Figure 2.The Raman spectra files are:HOP11a-MIa_<i>pt25_5%_750high_30sx8.txt</i>HOP11a-MIa-ol_<i>pt25_5%_750high_30sx8.txt</i>Ja2-Plot5-Grain4_<i>pt27-ol_5%_750high_30sx8.txt</i>Ja2-Plot5-Grain4_<i>pt35_5%_750high_30sx8.txt</i>

本文件夹收录了Buso等人2025年发表于《通讯地球与环境（Communications Earth & Environments）》的论文《熔体包裹体揭示大陆板内火山作用引发的大规模二氧化碳排放》的补充数据表（TS1至TS6）与四组原始拉曼光谱数据。各补充数据表详情如下：
补充数据表1：板内环境下原生岩浆与熔体包裹体的二氧化碳（CO₂）含量数据库。
补充数据表2：下维瓦赖（Bas-Vivarais）未加热熔体包裹体的玻璃组分实测原始电子探针微区分析（EPMA）数据。
补充数据表3：下维瓦赖未加热熔体包裹体的玻璃组分实测数据，经MIMiC校正质子诱导电荷交换（PEC）效应后的数据集。
补充数据表4：经高压均一后的下维瓦赖熔体包裹体的玻璃组分实测原始电子探针微区分析（EPMA）数据。
补充数据表5：经高压均一后的下维瓦赖熔体包裹体的玻璃组分实测数据，经MIMiC校正质子诱导电荷/电荷位移（PEC/PED）效应后的数据集。
补充数据表6：选取的近期与历史火山喷发事件中，每喷发1立方千米岩浆所对应的二氧化碳（CO₂）排放量。

上述文件所引用的参考文献可于补充信息文件中查阅。

本批次原始拉曼光谱数据（txt格式文件）用于制作本文的图2，对应两个样品：分别为法国中央地块（French Massif Central）下维瓦赖火山省的未均一化熔体包裹体Ja2-Plot5-Grain4，以及均一化熔体包裹体HOP11a-MIa。本文件夹同时收录了在这两个包裹体旁的橄榄石中测得的两组光谱，可用于校正橄榄石污染对光谱的影响。所有拉曼光谱均已按照论文所述方法完成处理，以生成图2所需的最终数据。
