In-situ trace element compositions of clinopyroxene and amphibole crystals in plutonic xenoliths from St Vincent, Lesser Antilles arc

This dataset presents in-situ trace element compositions of clinopyroxene and amphibole crystals in plutonic xenoliths (erupted fragments of crystal mush) from the island of St Vincent in the Lesser Antilles volcanic arc, measured using LA-ICP-MS. The samples were collected from pyroclastic deposits on the flanks of La Soufrière volcano on St Vincent. The crystal trace element data was used to assess fractional crystallisation and melt-mush reaction processes within the St Vincent magmatic plumbing system.

本数据集收录了小安的列斯火山弧（Lesser Antilles volcanic arc）圣文森特岛深源捕虏体（即晶粥喷发碎屑）中单斜辉石（clinopyroxene）与角闪石（amphibole）的原位微量元素组成，相关数据通过激光剥蚀电感耦合等离子体质谱法（LA-ICP-MS）测得。样品采集自圣文森特拉苏弗里耶尔火山侧翼的火山碎屑沉积。该晶体微量元素数据被用于评估圣文森特岩浆通道系统内的分离结晶作用与熔体-晶粥反应过程。
