The middle section of the northern margin of the North China Craton (also referred to as the study area) is situated in the junction between the North China Craton and Bainaimiao arc. With the Chifeng-Bayan Obo fault as the boundary, its southern and northern parts fall within different geotectonic units and have different basement features. Permian magmatites are widely distributed across the northern margin of the North China Craton and are exposed on both sides of the fault zone. Their provenance consists of very complex components, constricting fuller understanding of the petrogenesis and tectonic background of the magmatites. The Chifeng-Bayan Obo fault is covered by two geological survey projects, one involves four map sheets including the Beiliutumiao map sheet, and the other covers two map sheets including the Wulanbulage map sheet. In this paper, the testing data of chronology, geochemistry, and zircon Hf isotopes of the Permian magmatites in all six map sheets from the two projects were integrated and analyzed based on the regional geological surveys on a scale of 1∶50 000 of the two projects. The aim is to provide detailed and accurate data for further research of the provenance and the tectonic-magmatic evolution process of Permian magmatites in the study area. Furthermore, Permian intrusions are also widely exposed in the study area, which mainly include granodiorites, (quartz) diorite, monzogranite, and a small number of syenite granites. Permian volcanics are mainly distributed to the south of the fault zone and consist of andesitic and dacitic volcanics as well as a small number of rhyolitic volcanics. As shown by zircon U-Pb dating, the Permian magmatites within the study area were mainly formed in mid-late Permian, and the magmatites on the northern and southern sides of the fault zone have distinctly different zircon Hf isotopic characteristics. In short, zircon Hf isotopes are rich on the southern side but depleted on the northern side. The datasets of chronology, geochemistry and zircon Hf isotopes of Permian magmatites in the study area (also referred to as the Dataset) include three.xls files (Zircon U-Pb dating data.xls, Zircon Hf isotope data.xls and Whole-rock geochemistry data.xls), which are comprised of data on the petrogeochemistry of 104 samples, zircon U-Pb dating of 16 samples and zircon Hf isotopes of 12 samples. Samples collected for the Dataset were mainly tested in the Experiment and Test Center of Tianjin Center, China Geological Survey, and thus the data obtained are credible.
