Fig. 5From: Paleomagnetic directional groups and paleointensity from the flood basalt in the Tarim large igneous province: implications for eruption frequencyHysteresis parameters on a Day plot. Filled circles represent bulk samples, and other symbols represent plagioclase crystals. The combination of the parameters defines regions corresponding to “single-domain (SD),” “pseudo-single domain (PSD),” and “multi-domain (MD)” characters, as outlined on the plot. Dashed lines are single-domain–multi-domain mixing curve after Dunlop (2002)Back to article page
