Daily time series of matrix glass composition from tephra samples from the 2021 Tajogaite eruption at Cumbre Vieja volcano (La Palma, Canary Islands)

Ash and lapilli samples were continuously collected during the 2021 eruption of Cumbre Vieja volcano. This dataset reports the major and volatile (S, Cl) element compositions of matrix glasses from these samples. Data were acquired by electron probe microanalysis at the American Museum of Natural History and are given for 85 samples and 4 duplicates, resulting in a daily time series of erupted melt composition capturing 94% of the eruptive sequence.

在2021年Cumbre Vieja火山爆发期间，连续收集了火山灰和火山弹样品。本数据集报告了这些样品中基质玻璃的主要和挥发性元素（S，Cl）组成。数据通过美国自然历史博物馆的电子探针微分析获得，涉及85个样品及4个重复样品，从而形成了一个每日时间序列的爆发熔融成分，捕捉了94%的爆发序列。
