This dataset contains the sequence data of the lake core TOC, CaCO₃, particle size and environmental magnetism parameters from 600 years to 1998 of Yamdrog Yumtso in the southern part of the Tibetan Plateau. It is used to study the environmental changes in the Yamdrog Yumtso region in the 1400 years. This data set is obtained from laboratory measurements. The data are obtained immediately after the completion of the instrument or experiment. The samples and data are collected in strict accordance with relevant operating procedures at all stages and comply with the laboratory operating standards. The TOC analysis is undertaken by a CS-344 analyzer, The CaCO₃ content is measured by the general chemical method, the particle size is measured with a Malvern Mastersizer 2000 laser particle sizer, and the environmental magnetism parameters are measured with a Kappa Bridge, DIGICO magnetometer and superconducting magnetometer. The rock core was collected from Chen Co Lake in the Yamdrog Yumtso Basin in the southern part of the Tibetan Plateau; the approximate sampling location is 90.49E, 28.93N, and the lake’s elevation is 4420 m.
ZHU Liping
This data set is the result of systematic zircon Hf isotope testing performed on granites in the Bangong Lake, Gaize, Dongqiao and Anduo areas of south Qiangtang using the multireceiving Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrum (LA-MC-ICP-MS) method. The data were obtained according to laboratory standards, and the quality met laboratory requirements. The data are mainly used in geological research of the Tibetan Plateau.
LIU Deliang
This dataset contains the precipitation (P), river water (R) and lake water (L) isotope records for Lhasa and the Yamdrog Yumtso basin (including Yamdrog Yumtso 90°08′ E - 91°45′ E, 28°27′ N - 29°12′ N, 4440 m, and Pumayum Co 90°13′ E - 90°33′ E, 28°29′ N - 28°38′ N, 5030 m) and the Nam Co Basin (90°16′ E - 91°03′ E, 30°30′ N - at 30°56′ N, 4718 m) on the Tibetan Plateau. It can be used for studies on stable isotope observations of precipitation, river water and lake water in typical areas of the plateau. The precipitation, river and lake water samples are collected in selected typical areas, and the values of stable isotopes are measured by a gas stable isotope ratio mass spectrometer (MAT-253-IRMS) after sealed storage. A data sheet is entered by a specific person based on the measurement results. The data in this dataset are from observations and measurements obtained in strict accordance with the sample collection specifications and have been published in relevant academic journals; the stable isotope of all samples is measured using the MAT-253 gas mass spectrometer at the Key Laboratory of Environment Changes and Land Surface Processes of the Institute of Tibetan Plateau Research, Chinese Academy of Sciences. Samples are cryopreserved before measurement. The measurement results are the part per thousand deviations from V-SMOW; some obvious error data are eliminated when processing to generate the data table.
YAO Tandong
This data set contains stable oxygen isotope data of daily precipitation in Lulang, Nuxia, and Guangzhou from 2007 to 2014. The precipitation data of the Lulang station are obtained via automatic weather station (AWS) rain gauges, and the precipitation data for Guangzhou and Nuxia are the manual records of meteorological or hydrological stations. Project source of the data: the general project of the National Natural Science Foundation of China “Exploring the impact of ENSO on the source of water vapor in the north and south of the ‘third pole' through stable isotope of precipitation and ice core” (41571074). Data processing related information can be found in the following reference: Yang, X, Mary E. Davis, Sunil Acharya, Tandong Yao. Asian Monsoon variations revealed from stable isotopes in precipitation. Climate Dynamics, 2017, doi:10.1007/s00382-017-4011 -4. Data collection sites: Lulang Station of Southeast Tibet, Chinese Academy of Sciences, Longitude: 94.73°E; Latitude: 29.77°N; Altitude: 3330 m. Guangzhou weather station, longitude: 113.32 °E; latitude: 23.13 ° N; altitude: 7 meters. Nuxia hydrological station, longitude: 94.65 °E; latitude: 29.47 ° N; elevation: 2920 m.

By archaeological investigation and excavation in Tibetan Plateau, we discovered 8 Neolithic and Bronze Age sites, including Gaomuxudi, Duojialiang, Shuikou, Qipanshan, Xinzhai, Canxionggasu, Niaodao, Bangga, Baiyangcun and so on. In this dataset, there are some basic informations about these sites, such as location, longitude, latitude, altitude, material culture and so on. On this Basis, we identified animal remains, plant macrofossil, selected some samples for radiocarbon dating and stable carbon and nitrogen isotopes. This dataset provide important basic data for understanding when and how prehistoric human lived in the Tibetan Plateau during the Neolithic and Bronze Age.
