Tholeiitic magmatic record on an extensional passive continental margin: Constraints from Late Paleozoic Woniusi rock associations in the Baoshan block, SE Tibetan Plateau

Basaltic samples of the Woniusi rock associations collected from the northern, middle, and southern parts of the Baoshan block. These samples were analysed for zircon U-Pb-Hf dating and whole-rock elemental and Sr-Nd isotopic data.
