Volcanic Pumices

Two volcanic pumices, imaged once as a whole and once after being cut and made into an epoxy mount. Pumice 1_2 is highly vesicular, basaltic scoria sample from 2021 Fagradalsfjall eruption. Likely erupted in late May. Pumice 5 is highly vesicular, basaltic scoria sample from 2021 Fagradalsfjall eruption. Erupted around 28th April. To be used in a publication.

本数据集包含两块火山浮石（volcanic pumice），分别对其完整样本以及经切割并制成环氧树脂镶样（epoxy mount）的样本完成成像。浮石1_2为2021年法格拉达尔（Fagradalsfjall）火山喷发产生的、具高度发育气孔构造的玄武质火山渣（basaltic scoria）样本，其喷发时间大概率为5月下旬。浮石5同样为2021年法格拉达尔火山喷发产生的具高度发育气孔构造的玄武质火山渣样本，喷发时间约为4月28日。本数据集将用于学术出版。可通过以下链接获取数据集预览：https://doi.org/10.23729/bfc7baf6-1798-40fd-b14b-aa4db7c47d6c。如需获取完整数据集，请联系邮箱[e-mail]。
