Bulk, molecular and isotopic data from 2.1 to 0.6 Ma on southeastern Loess Plateau
Description
We present magnetic susceptibility (SUS), abundance and carbon isotope composition of total organic carbon (TOC), BC abundance and br-GDGT-derived mean annual temperature (MAT) and mean annual precipitation (MAP) records over a glacial-interglacial scale during ~2.1-0.6 Ma from a loess/paleosol sequence at Shangchen (SC, 34°13′33″N, 109°28′39″E) and br-GDGT-derived MAT and MAP records in several loess/paleosol layers (L6, L9, L13, S14, S15, L22, S22, L25, S25, L26 and S26) from Duanjiapo (DJP, 34°11′15″N, 109°13′58″E) on southeastern Chinese Loess Plateau. Our data demonstrate four climate-vegetation periods during 2.1-0.6 Ma at SC, high climatic and environmental variability during the early mid-Pleistocene climate transition (MPT, ~1.26-0.9 Ma) at SC and a cooling and aridification trend since the beginning of MPT (~1.26 Ma) in this area. We assume the data can be used to reconstruct the paleoclimate and paleoenvironment during ~2.1-0.6 Ma on southeastern Chinese Loess Plateau.
