Fig. 6.From: Paleointensity determination of Late Cretaceous basalts in northwest South Korea: implications for low and stable paleofield strength in the Late CretaceousPlot of hysteresis ratios (Mrs/Ms and Bcr/Bc) (Day plot; Day et al., 1977) representing the dominant domain states of magnetic minerals within the samples. Single-domain (SD), multi-domain (MD), and superparamagnetic (SP) mixing lines of Dunlop (2002) are shown in grey. Numbers alongside the curves are volume fractions of SP or MD particles present in mixtures with SD grains.Back to article page
