Geochemical and isotopic data of Triassic calc-alkaline lavas in the Peloponnese, Greece

The dataset contains major and trace element concentrations as well as Sr and Nd isotope compositions of Triassic calc-alkaline lavas in the Peloponnese, Greece. The data represent lithotypes that include basaltic andesites, andesites and rhyodacites, classified as medium-K calc-alkaline rocks. These data shows that the lavas were formed in forearc settings and were variably affected by fractional crystallization as well as crustal assimilation processes. Major elements were determined by XRF, trace elements by LA-ICPMS, isotope data by TIMS. The interpretation and discussion of these data form part of a manuscript submitted to Geochemistry, Geophysics, Geosystems.本数据集涵盖希腊伯罗奔尼撒半岛（Peloponnese）三叠纪钙碱性熔岩的主量元素（major elements）、微量元素（trace elements）浓度数据，以及锶（Sr）与钕（Nd）同位素组成数据。本次数据集涉及的岩性包括玄武安山岩（basaltic andesites）、安山岩（andesites）与流纹英安岩（rhyodacites），均归属于中钾钙碱性岩系（medium-K calc-alkaline rocks）。数据表明，上述熔岩形成于弧前构造环境（forearc settings），并在不同程度上受到了分离结晶作用（fractional crystallization）与地壳同化作用（crustal assimilation）的影响。主量元素通过X射线荧光光谱法（X-ray Fluorescence, XRF）测定，微量元素通过激光剥蚀电感耦合等离子体质谱法（Laser Ablation Inductively Coupled Plasma Mass Spectrometry, LA-ICPMS）测定，同位素数据则通过热电离质谱法（Thermal Ionization Mass Spectrometry, TIMS）获得。对本数据集的解读与讨论，是投稿至《地球化学、地球物理学、地球系统》（Geochemistry, Geophysics, Geosystems）期刊的一篇学术论文的组成部分。
