Dataset for: Crust–Mantle Architecture Beneath the northwestern West Qinling Orogen (China): Constraints from Middle Triassic Arc-Affinity Mafic Igneous Rocks

Supplement to: Feng-Hui Zou, Jian-Ping Zheng, Xiang Zhou, & Qiang Ma (2026), "Crust–Mantle Architecture Beneath the northwestern West Qinling Orogen (China): Constraints from Middle Triassic Arc-Affinity Mafic Igneous Rocks", Journal of Geophysical Research: Solid Earth This dataset contains: - Major element compositions of minerals (plagioclase, clinopyroxene, amphibole, biotite) for mafic igneous rocks. - In-situ Sr isotope of plagioclase. - Zircon U-Pb age and Hf isotopic analysis. - Whole-rock chemical analysis of mafic igneous rocks. - Whole-rock Sr-Nd-Mg isotopic analysis of mafic igneous rocks The dataset supports the figures, tables, and statistical analyses in the associated manuscript. Complete methodological descriptions are provided in the publication.
