Sample AK1, with a low X value, is from an Alaskan palaeosol equivalent to the peak of marine oxygen isotope (MOI) stage 3, while samples AK2 and AK3 are loess samples, with higher X, from the transition between MOI stages 5 and 6.
Even sample AK2, an intermediately developed soil in Alaska (Fig.
The softest sample is neither soil AK1 nor loess AK3, which have similar values, but weakly developed soil AK2.
But compared with the Xifeng loess samples, samples AK2 and AK3 have higher MD and lower SP contributions.
The 2 stronger magnetic samples, loess AK3 and weakly developed soil AK2, show a loss of Ms percentage during heating and visible concavity around 350 [degrees] C in the heating curve, indicating the presence of higher concentrations of maghaemite than the Xifeng samples.
s](%), SP, SD, and MD listed in Table 1 and 2 demonstrate a clear gap between weakly weathered loess AK2 and strong weathered loess AK1.
