Data for: The age and geochemistry of the mid-Cretaceous volcanic rocks in the Jinan Basin: Implications for the tectonic environments of the Korean Peninsula and Northeast Asia

we performed zircon U-Pb age dating by a laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) analysis for sedimentary and volcanic rocks to constrain the age of sedimentation and igneous activities in the Jinan Basin. The whole-rock major and trace elements and Sr-Nd-Pb isotope geochemistry of the volcanic rocks in the Jinan Basin were determined to investigate their petrogenesis and infer the tectonic setting of the southern Korean Peninsula during the mid-Cretaceous.
