Provenance discrimination diagrams integrating immobile trace elements and REE for the Harbin loess and paleosols. Geochemistry of loess deposits in northeastern China: constraint on provenance and implication for disappearance of the large Songliao palaeolake

Supplementary Fig. 3: Provenance discrimination diagrams integrating immobile trace elements and REE for the Harbin loess and paleosols. Note that the Harbin dust samples fall within the field of the Songnen Sandy Land and the Horqin Sandy Land but far outside the field of the Hulun Buir Sandy Land, revealing a geochemical affinity of the Harbin aeolian loess with the the Songnen Sandy Land and Horqin Sandy Land.
