Bulk magnetic susceptibility was measured using a Kappabridge (KLY-4 or MFK1, AGICO). Anisotropy of magnetic susceptibility (AMS) was measured using the manufacture's SUFAR software program, and bulk susceptibility was calculated from the AMS tensor. Chemical digestion by citrate-bicarbonate-dithionite, and sodium pyrosulfate fusion to extract eolian feldspar and quartz. XRD analysis was conducted using a diffractometer (MiniFlex II, Rigaku) with Cu Ka radiation. The samples were first dispersed in a 0.2 % sodium hexametaphosphate solution and sonicated for 1h. The dispersed sample was then introduced into a laser diffraction particle size analyzer (Mastersizer 3000E, Malvern Panalytical).
This dataset has been carefully reviewed and curated in accordance with PANGAEA's exceptionally high quality standards. However, due to discontinued communication from the authors' side, it did not receive the usual formal approval by the authors and therefore lacks final scientific validation.
