a Thermal demagnetization of the orthogonal three-component IRM: circles indicate the low-coercivity component of the 0.12 T field, triangles indicate the medium-coercivity component of the 0.4 T field, and squares indicate the high-coercivity component of the 2.5 T field. b Plot of IRMZ versus IRMX showing the gradient of the best-fit correlation line, providing an estimate of the inclination shallowing in sediments. c TiO2–FeO–1/2Fe2O3 ternary diagram showing chemical compositions of hematite grains in a sample with a laboratory unblocking temperature of 685 °C (HY4-3). Minor components are allocated as follows: FeO = ΣR2+ = Fe2+ + Mg + Mn; Fe2O3 = 1/2ΣR3+ = 1/2(Fe3+ + Al); TiO2 = ΣR4+ = Ti + Si. d Normalized remanence intensity curves for representative samples. An abrupt decay in intensity is observed in the shaded temperature range (650–695 °C), which is characteristic of DRM (Jiang et al. 2015)
