Geochemical elements and magnetic parameters of a 49-m basaltic red soil core on Hainan Island, China

The attached files (ordered from 1 to 6) are the geochemical and magnetic parameters for a 49-m red soil core derived from multi-layer basalt in northern Hainan Island, China. File 1 to 4 are excel format. File 5 and 6 were compressed files. File 1 contains data of geochemical elements (Fe, Al, Ti and Th) of the 49 m-red soil. File 2 contains basic magnetic parameters, such as χ, ARM and IRM. File 3 are hysteresis data for day-plot. File 4 are data for selected hysteresis loops. File 5 are data for first order reversal curves (FORC) diagram (.frc format); it can be viewed as txt or processed with FORC software, such as FORCinell. File 6 are data for IRM acquisiton and unmixing curves.
