Mineralogy and isotopes data for carbonate nodules occured in western Qaidam Basin
This database includes the identification of the mineralogy and the stable C and O isotopes of the nodules collected from western Qaidam Basin. Mineralogy was analyzed by XRD, SEM, XRF and EPMA measurements. Stable isotopes of every nodule were analyzed in the University of Alberta. U and Th isotopes were analyzed in Xi'an Jiaotong University. We also put the geological maps of the study area in Qaidam Basin.
