“…The evolutionary history of source rocks and paleogeothermal gradient in the Ordos Basin is analysed in the study byYu et al (2017). The rare earth elements geochemistry of lacustrine oil shales in the Ordos Basin are described in a paper by D.. Geochemical and petrological analysis of Permian Wangpo shale from Shaanxi Province forms the basis of a study byShao et al (2017), who recognize its volcanic affinity and compare it with K-bentonites.The discovery of Mesoproterozoic magmatic zircons is used byCao et al (2017) to demonstrate the Precambrian tectonic affinity of the North Qinling Microcontinent. Yang, Li, Tong, Wang, and Wu (2017) provide an overview of ophiolitic mélanges in the Central China Orogen.…”
