Impacts of iron redistribution on the formation of pedogenic magnetic minerals in a basaltic red soil 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.本次附呈的按1至6编号排序的文件，为取自中国海南岛北部多层玄武岩之上的49米厚红土岩芯的地球化学与磁学参数数据集。其中文件1至4均为Excel格式文件，文件5与6为压缩打包文件。文件1存储该49米红土岩芯的地球化学元素数据，包含铁（Fe）、铝（Al）、钛（Ti）与钍（Th）。文件2收录基础磁学参数，包括磁化率（χ）、非磁滞剩磁（Anhysteretic Remanent Magnetization, ARM）与等温剩磁（Isothermal Remanent Magnetization, IRM）。文件3为用于生成Day图（Day-plot）的磁滞回线数据。文件4为筛选后的磁滞回线数据集。文件5为一阶反转曲线（First Order Reversal Curves, FORC）图数据，格式为.frc；可通过文本编辑器以TXT格式查看，或使用FORCinell等FORC专用软件进行处理。文件6为等温剩磁（Isothermal Remanent Magnetization, IRM）获取与解混曲线数据集。
