Proto-monsoon rainfall and greening in Central Asia due to extreme early Eocene warmth

Here we present paleo-environmental datasets derived from early Eocene sedimentary strata in the Xining Basin, China. The sedimentary rocks were formed in a terrestrial alluvial mudflat environment and the datasets include: 1) Pollen counts, 2) Bulk rock organic carbon content and δ13C values, 3) Plant wax compound specific (C27-C33) δ13C values, 4) Bulk mineralogy X-Ray Diffraction (XRD) data and 5) Carbonate (pedogenic and vadose-grown) δ13C and δ18O values as well as clumped isotopes (∆47 values). The latter also includes temperature reconstructions derived from the ∆47 values and soil water δ18O reconstructions derived from these temperatures and the carbonate δ18O values. Individual clumped isotope measurements of sample and standard replicates are shown in: 6) Clumped isotope replicate analyses. […]
