Dataset for: The volcanism of the Meseta del Lago Buenos Aires, Patagonia: the transition from subduction to slab window

Dataset for manuscript entitled, "The volcanism of the Meseta del Lago Buenos Aires, Patagonia: the transition from subduction to slab window " by Guest et al. published in Journal of Petrology. Here we report new major, minor and trace element contents, as well as Sr, Nd, Pb, and Hf isotopes of the Meseta del Lago Buenos Aires (MLBA) lavas. We also report estimated mantle equilibration temperatures and pressures of MLBA lavas after correction for olivine fractionation after Plank and Forsyth (2016). Additionally, we report new Hf and Pb isotopes of lavas erupted along the Chile Ridge.

《巴塔哥尼亚湖泊巴恩塞塔火山活动：从俯冲带至板块窗的过渡》一文的稿件数据集，作者为Guest等，发表于《岩石学杂志》。本数据集报告了新近测定的巴恩塞塔湖泊地区（MLBA）火山岩的主要、次要和微量元素含量，以及Sr、Nd、Pb和Hf同位素。此外，还提供了对MLBA火山岩在修正橄榄石分离效应后，根据Plank和Forsyth（2016年）方法估算的地幔平衡温度和压力。同时，报告了沿智利海脊喷发的火山岩的新Hf和Pb同位素数据。
