埋藏火山的原位碳储存潜力
作者:小柯机器人 发布时间:2023/5/19 9:38:47

葡萄牙里斯本大学的Ricardo Pereira和阿威罗大学的Davide Gamboa研究埋藏火山的原位碳储存潜力取得新进展。2023年5月16日,国际知名学术期刊《地质学》发表了这一成果。

研究人员调查了一个部分埋藏的晚白垩世的复合火山,作为全球大陆边缘火山机构中潜在原位矿物碳酸化的代表,该火山位于西伊比利亚边缘近海的中部。研究人员基于地震资料、地球化学和岩石物理性质,对永久性碳储存的确定性情景进行了估计。总体分析火山的性质和其内部结构显示,这一单一的体系有可能在新形成的碳酸盐矿物组合中储存1.2-8.6 Gt的CO2。研究结果表明,大陆边缘古老的地下火山构成了安全碳储存的有利场所,其总CO2储存量高达数百亿吨。

据悉,在多孔和可渗透的镁铁质和超镁铁质火山岩中的原位矿物碳酸化被认为是一种有前途的方法,有助于安全和永久的CO2封存。

Title: In situ carbon storage potential in a buried volcano

Abstract: In situ mineral carbonation in porous and permeable mafic and ultramafic volcanic rocks is proposed to be a promising process that can contribute toward safe and permanent CO2 sequestration. Here, we investigated a partially buried Late Cretaceous composite volcano located offshore the central West Iberian margin as a proxy for potential in situ mineral carbonation in volcanic edifices on continental margins worldwide. Based on seismic data, geochemistry, and petrophysical properties, deterministic scenarios for permanent carbon storage were estimated. Overall analysis of the nature of the volcano and its internal architecture revealed that this single edifice has the potential to store 1.2–8.6 Gt CO2 in newly formed carbonate mineral assemblages. Results suggest that ancient, buried volcanoes on continental margins constitute auspicious sites for safe carbon storage, with a total storage capacity of hundreds of gigatonnes of CO2.
