1) Data Content: Rock magnetic data, including indicators such as hard isothermal remanent magnetization and frequency-dependent magnetic susceptibility. These magnetic proxies can be used to reconstruct paleoclimate changes during geological history.
2) Data Source and Processing Methods: The data originate from laboratory experiments. For the magnetic data: Field-collected samples were ground into fine particles with a mortar, loaded into 2×2×2 cm non-magnetic plastic boxes, and tested using a Kappabridge magnetic susceptibility meter, pulse magnetometer, and rotating sample magnetometer.
3) Data Quality: Sample collection and experimental processing were carried out in strict accordance with relevant standards, and the resulting data are of reliable quality.
4) Data Application Achievements and Prospects: One peer-reviewed SCI paper has been published using this dataset.
