Fifteen Lower Permian siliciclastic rocks from central Tibet were analysed for the major and trace elements, and ten samples among them were chosen for determination of Nd isotopic compositions. They are characterized by low concentrations of SiO2 and low ratios of SiO2/Al2O3, moderate abundances of Fe2O3 + MgO (mudstones, 7.28–9.72 wt.%; sandstones, 4.62–10.02 wt.%) and TiO2 (mudstones, 0.55–0.95 wt...
The Permian sedimentary rocks in the Turpan–Hami Basin are key records of the tectonic evolution in the Eastern Tianshan area, although their depositional ages and provenances remain relatively less studied. Here, we conducted detrital zircon U–Pb geochronology on subsurface samples collected from Well LN1 in the Turpan–Hami Basin to understand the depositional ages and provenances of the Permian...
