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.
