Fig. 2From: Age constraints on island-arc submarine basalts from geomagnetic paleointensityTemperature dependence of magnetic susceptibility (k). Data are normalized by the room temperature susceptibility before heating (k0). Orange solid lines show heating curve, and blue dashed lines show cooling curve. a–f Heating in Ar. g Heating in air for the sample HPD#1000-R09. h Heating in Ar after paleointensity experiment involving heating to 500 °C in vacuum for the sample HPD#1000-R10Back to article page
