Matrix glass composition of tephra samples from El Hierro's Tanganasoga volcano and western rift (Canary Islands)

This dataset reports the major and volatile (S, Cl) element compositions of matrix glasses from tephra samples from the Tanganasoga volcano and the western rift on the island of El Hierro, in the Canaries. Data were acquired by electron probe microanalysis at McGill University. Results show a wide range of compositions from basanite (for scoria lapilli) to trachyte (pumice lapilli and ash).

本数据集记录了加那利群岛耶罗岛坦加纳索加火山及西裂谷带火山碎屑样品的基质玻璃主量与挥发性（硫S、氯Cl）元素组成。数据由麦吉尔大学（McGill University）采用电子探针显微分析（electron probe microanalysis）方法测得。分析结果显示样品组成跨度极广，涵盖对应火山渣火山砾的碧玄岩至对应浮石火山砾与火山灰的粗面岩。
