Holocene climate change recorded of Milanggouwan and Dishaogouwan sedimentary profile in the Salawusu River Basin
Abstract This paper investigates the MGS1 sedimentary profile and the DGS1 sedimentary profile (37° 41′–37° 45′ N, 108° 29′–108° 35′ E) to analyze the mean particle size (Mz), oxides and trace elements, chemical index of alteration (CIA), scanning electron microscopy (SEM) images, and their correlat...

| description | Abstract This paper investigates the MGS1 sedimentary profile and the DGS1 sedimentary profile (37° 41′–37° 45′ N, 108° 29′–108° 35′ E) to analyze the mean particle size (Mz), oxides and trace elements, chemical index of alteration (CIA), scanning electron microscopy (SEM) images, and their correlation with regional Holocene climate fluctuations in the Salawusu River Basin. The results demonstrate that the chemical element variations in MGS1 and DGS1 align with the aeolian dune facies, lacustrine facies, and paleosol. The climatic information reflected by oxides like SiO2 and trace elements like Sr shows temporal and spatial consistency, suggesting an obvious response to desert monsoon climate changes in northern China. The Holocene climate in the Salawusu River Basin is characterized by four periods of fluctuation: early Holocene warming (11,020–10,290 Yr BP), Holocene maximum warmth (10,290–6590 Yr BP), Holocene warm-cold transition (6590−3760 Yr BP), and Holocene cold-dry climate instability (3760–0 Yr BP). |
