Fig. 3From: Paleomagnetic studies on single crystals separated from the middle Cretaceous Iritono graniteHistogram of NRM intensity of a zircon, b quartz and c plagioclase. Dotted lines indicate the threshold for significant remanence. Inset figures in a and b show the histogram of NRM intensity above the threshold (4 × 10−12 Am2)Back to article page
