Oregon State University LA-ICP-MS Method for Plagioclase Trace Element Analysis

This dataset describes the method used to collect plagioclase trace element analyses in the W.M. Keck Collaboratory for Plasma Spectrometry at Oregon State University using an Applied Spectra RESOlution ArF Excimer laser system connected to a ThermoFisher Scientific iCAP-RQ ICP-MS. Analytes include Li, Mg, Al, Si, Ca, Ti, Fe, Sr, Ba, La, Ce, Eu, and Pb. Plagioclase were analyzed along transects using 5-by-50-micron spots, with the long side perpendicular to the transect, and 5-micron spacing between spot centers.

本数据集详述了美国俄勒冈州立大学W.M.凯克等离子体光谱学协作实验室（W.M. Keck Collaboratory for Plasma Spectrometry）中，采用一台与赛默飞世尔科技（ThermoFisher Scientific）iCAP-RQ型电感耦合等离子体质谱仪（ICP-MS）联机的Applied Spectra RESOlution ArF准分子激光剥蚀系统，开展斜长石微量元素分析的完整方法。本次分析涵盖的目标元素包括锂（Li）、镁（Mg）、铝（Al）、硅（Si）、钙（Ca）、钛（Ti）、铁（Fe）、锶（Sr）、钡（Ba）、镧（La）、铈（Ce）、铕（Eu）与铅（Pb）。斜长石样品沿测线进行分析，采用5×50微米的剥蚀斑点，斑点长边垂直于测线走向，且相邻斑点中心间距为5微米。
