Rock magnetic data for the research of the Northeastern Jiangxi Ophiolite

This file contains the rock magnetic data for the paper "High H2 Production from Serpentinization of Ocean Crust between the Yangtze and Cathaysia Blocks." Provided datasets include hysteresis loops, isothermal remanent magnetization (IRM) acquisition curves, first-order reversal curves (FORCs), and magnetic susceptibility–temperature (χ–T) curves. Sample name, maximum applied field, and measurement step size are indicated in each subfile name.
