Geochemical and Sr-Nd isotopic evidence for petrogenesis and geodynamic setting of Lower-Middle Triassic volcanogenic rocks from central Greece: Implications for the Neotethyan Pindos ocean

Geochemistry and Sr-Nd isotopes were determined in Triassic calcalkaline metalava and metapyroclastic rocks from Attica and Argolida, central Greece, to ascertain their origin, evolution, and emplacement timing. Sample protoliths were lavas, tuffs, and, subordinately, tuffites of basaltic to rhyolitic composition. Despite up to low-grade hydrothermal metamorphism, samples retain primary structures and geochemical characteristics; in particular,...
