The dataset presented here is associated with the article “Young Silicic Magmatism of the Greater Caucasus, Russia with implication for its delamination origin based on zir- con petrochronology and thermomechanical modeling”[1] . We present detailed sample descriptions and source locations for the rocks from the Chegem, Tyrnyauz, and Elbrus volcanic center localities presented in that study. The dataset presents extensive isotope and trace element geochemistry of zircon crystals from these rocks, major phenocrysts, and whole rock O and H isotopic and elemental compositions. Zircon ages, trace element compositions, and Hf and O isotopic composi- tions were obtained by both laser ablation ICP-MS and sec- ondary ionization mass spectrometry in situ techniques and chemical abrasion isotope dilution-thermal ionization mass spectrometry techniques. We also present whole-rock ma- jor element compositions obtained by X-ray fluorescence and trace element compositions obtained by solution inductively- coupled plasma mass spectrometry. We also report δ18 O analyses of phenocrysts and groundmass in samples, δ18 O- δ13 C analyses of limestones and limestone xenoliths in the Chegem ignimbrite, and coupled δ18 O- δD- Delta17 O analyses of glass and groundmass of rock samples from the Chegem ign- imbrites that show abundant evidence of post-emplacement interaction with meteoric waters. To supplement the associ- ated study [1] , this article also includes field photographs, cathodoluminescence images of zircons, plots of trace ele- ment compositions in zircon, plots of stable isotopic vari- ations in Chegem ignimbrites vs. stratigraphy, and selected trace elemental whole-rock diagrams.
