Zircon HF-O data sets of magmatic rocks in the Qinghai Tibet Plateau are mainly based on zircon HF-O isotopic data of local areas from the South Qiangtang to Lhasa plate. Zircon HF-O test points are mainly concentrated in guoganjianian mountain, baohu, Duguer of South Qiangtang and saga County of Lhasa plate. The rocks are mainly mafic dyke swarms, gneissic granite and diorite. Zircon HF-O was measured by MC-ICP-MS and Sims, respectively. The data comes from published articles or in the acceptance stage. The data were published in SCI or Ni journals, including geology, BSA bulletin and Journal of petroleum, and the data results were true and reliable. The main testing unit is Guangzhou Institute of geochemistry, Chinese Academy of Sciences. The data set can be used to study the petrogenesis and lithospheric evolution of magmatic rocks in different areas of the Qinghai Tibet Plateau.

Previous works have been undertaking on the geochemistry of some basic rocks within the Yaelung Zangbo suture zone, and it was proposed that the Jurassic-Cretaceous seamount type basement basic rocks are preserved in Zhongba and Renbu area. In this work, we conducted analysis of trace element for seventeen basic rock samples underlain below limestone blocks in Lhaze area within the central Yarlung Zangbo suture zone, southern Tibet. Results show that the rocks are dominated by basalts and have a feature of EMORB type with NMORB and OIB types. Combined with the overlain carbonates, these rocks are proposed the basement of paleo-seamounts, the Permian vestige preserved within the Yarlung Zangbo suture zone. This recognition of paleo-seamount implies that the Neotethys Ocean could have been already opened at the time (before the Middle Permian epoch).

With a depositional history spanning the early Aptian to early Albian (~19 mys), the Lower Cretaceous Xinminpu Group in Jiuquan, NW China provides abundant animal and plant fossils. This area is the represented study area of the Lower Cretaceous in China. The absence of a comprehensive stratigraphical framework for this area however limits the degree to which the unit can be interpreted relative to coeval sections and the geological records in genera. This investigation from July 9 to July 11 focuses on the Lower Cretaceous in this area, and collected abundant fossil and rock samples for biostratigraphic and stratigraphic analysis. This dataset includes: stratigraphic column of the Chijinpu Formation in the East Xiagou outcrop, and photographs of outcrops and represented fossils; stratigraphic column of the Xiagou Formation in the Changma outcrop and a photo of bird-bearing outcrop.

The data set includes soil pH data of representative soil samples collected from July 2012 to August 2013 in the Heihe River Basin. The first soil survey was conducted in 2012. After the representativeness evaluation of collected samples, we conducted an additional sampling in 2013. These samples are representative enough to represent the soil variation in the Heihe River Basin, of which the soil variation in each landscape could be accounted for. The sampling depths in field refer to the sampling specification of Chinese Soil Taxonomy, in which soil samples were taken from genetic soil horizons.

This data set comes from shallow marine carbonate sections at Tingri and Gamba, south Tibet. The age of these samples is about 56 Ma (at the Paleocene-Eocene boundary). At Tingri, we studied two parallel sections (13ZS section and 10-11TM section), and at Gamba, we studied one section (11TMG). From the 13ZS section, we analyzed carbon and oxygen isotopic compositions and calcium carbonate content of the whole carbonate rock, as well as the in-situ carbon isotopic compositions and element contents of the foraminifera shell. From the 10-11TM section, we analyzed carbon, oxygen and strontium isotopic compositions of the whole rock. From the 11TMG section, we analyzed carbon and oxygen isotopic compositions of the whole carbonate rock. Carbon and oxygen isotopic compositions of the whole rock were measured by gas isotope mass spectrometer (MAT251), strontium isotope by thermal ionization mass spectrometry (TIMS), calcium carbonate content by acid dissolution, in-situ carbon isotopic compositions by SIMS, and in-situ element contents by LA-ICPMS. Among these data, in-situ carbon isotope data were obtained from the laboratory of Professor John Valley at the University of Wisconsin-Madison in the United States, and the rest are from the relevant laboratories of the Department of Geosciences at the University of Bremen in Germany. Based on these data, we published three peer-reviewed papers on Journals of Gondwana Research, GSA Bulletin, and Global and Planetary Change.

The data include the carbonate content, carbon isotope and oxygen isotope analysis results of inorganic carbonates of 79 samples from 850 m natural section of the middle late Eocene in the salkuli basin. The carbon and oxygen isotopes of carbonate in the sediments record the hydrological and vegetation information in the geological history, which is one of the main indicators of paleoenvironmental tracer research. After grinding and sieving, the carbon and oxygen isotope analysis is completed by the sample processing unit (carbonate device) and MAT252 isotope mass spectrometry online automatic online system. The analytical accuracy of the sample is: carbon isotope is better than ± 0.06 ‰, and oxygen isotope is better than ± 0.08 ‰. Through the analysis of carbon and oxygen isotope data of solkuli section, the evolution history of arid environment since Eocene can be reconstructed, and the paleoclimate effect of the Tibetan Plateau uplift and global climate change can be discussed.

This dataset includes stable carbon and oxygen isotopes of carbonates in a 180 m-long sediment core retrieved from Lop Nor, Tarim Basin. Sedimentary carbon and oxygen isotopes from carbonates are two of the most commonly used proxies in paleoclimatic studies, as they have the potential to record past variations in hydrology and vegetation. The sediment samples were grounded and sieved through a 100 mesh screen, and then directly analyzed using an isotope ratio mass spectrometer (MAT-252) with an automated carbonate preparation device (Kiel Ⅱ). Typical analytical errors are within ±0.06‰ and ±0.08‰ for carbon isotope and oxygen isotope, respectively. Based on the high-resolution stable carbon and oxygen isotope data of core Lop Nor, the evolution history of arid environment in the Taklimakan Desert since the Pleistocene can be reconstructed, allowing further exploring of trends, variability and mechanisms of regional climate change. Field photos dataset of the Tibetan Plateau include photos of the stratigraphic profiles.

This dataset includes the concentrations and spatial pattern of mercury (Hg) in the soil of the southern Tibetan Plateau. Two hundred thirty nine soil samples were collected, and cold vapor atomic fluorescence spectrophotometry (CVAFS) was used to analyse the Hg contents. The limit of detection (LOD) for this method is 1.8 ng/g. The standard reference material, soil GB GSS-2, which is supplied by National Institute of Metrology P.R.China, was also analyzed for assessing the accuracy of this method, and the recoveries of this method were 84%-103%. This dataset will provide the informations of soil Hg contamination and background values over the southern Tibetan Plateau.
