Table 1 Summary of paleointensity results obtained using the conventional Thellier and LTD-Thellier methods.

Mrs/Ms is the ratio of saturation remanence to saturation magnetization. “HT fit” and “LT fit” denote the paleofield values (H) calculated by fitting high- and low-temperature segments of the Arai plot, respectively (see text). ΔH is the standard deviation.
