Qaidam Basin paleosols reflect climate and weathering intensity on the northeastern Tibetan Plateau during the Early Eocene Climatic Optimum
As an important geological archive, paleosols have been widely used in reconstruction of
paleoenvironmental and paleoclimatic conditions. In this study, we undertook detailed
analyses of the clay mineralogy and carbon and oxygen isotopic compositions of pedogenic
carbonates in a series of 13 paleosol horizons within a fluvial section of the Eocene (~ 52–
44 Ma) Lulehe Formation in the Qaidam Basin. Pedogenic smectite and illite/smectite (I/S)
mixed-layer minerals are the predominant clay minerals in the paleosols, suggesting that the …
