“…In fact, lots of HNBs and NEBs have been reported on the east coast of the Central Pacific as abnormal arc magmatism within the modern oceanic island arc system (Castillo, 2008;Hoernle et al 2008;Gazel et al 2011;Fletcher & Wyman, 2015). The subduction polarity of the SPTO is from south to north (ZL Li et al 2009;Yang et al 2009;Zhu et al 2010;Mai et al 2021;YM Li et al 2022), proved by the spatial distribution characteristics of the oceanic crust (ophiolites, oceanic islands; Chen et al 2010;Duan et al 2019Duan et al , 2022Zhong et al 2021), trench and initial fore-arc basin (Xie et al 2019(Xie et al , 2021 and arc magmatism (Geng et al 2009;Zhu et al 2010;GM Li et al 2020;B Wang et al 2020;Mai et al 2021;N Li et al 2022;Song et al 2022; from south to north. The intrusion time of the Yeqing gabbro is coincident with the period of the SPTO subduction in the early-middle Permian and middle-late Triassic by studying the eclogites (Li et al 2009;Cheng et al 2012Cheng et al , 2015Zhang et al 2018a, b), which is also proved by the contemporaneous arc magmatism mentioned above (Fig.…”

“…In the study area, the Nuoco Formation, formed in a continental margin environment, mainly consists of sandstone or metasedimentary rock on the north of the TSACB (Zhu et al 2013). The strata exposed in the TSACB is mainly Sumdo Formation, which is a set of low-grade-metamorphosed terrigenous clastic sandstones and mudstones formed in an initial fore-arc basin environment (Xie et al 2019(Xie et al , 2021. The Luobadui Formation exposes a little in the study area and is mainly composed of limestone, terrigenous sediments and arc-type volcanic rocks (Geng et al 2009;Zhu et al 2010;.…”

“…The slab window is common in slab break-off or ridge subduction, which are not suitable for this study. Moreover, the seismic ridge, a series of seamount island chains formed by oceanic crust moving over fixed hotspot/mantle plume, could bring about a slab window while subducting (Gazel Geng et al 2009;Yang et al 2009;Zhu et al 2009Zhu et al , 2010Cheng et al 2012Cheng et al , 2014Zhang et al 2018;Duan et al 2019Duan et al , 2022Xie et al 2019Xie et al , 2021B Wang et al , 2020Li et al 2020Mai et al 2021;Zhong et al 2021;Song et al 2022;. According to the discussion of petrogenesis and tectonic setting above, we propose that the hotspot/mantle plume began to interact with the subduction zone in the SPTO after the middle Permian, and the hotter plume material upwelled through a slab window intruding into the continental edge during the late Permian to early Triassic.…”

The Palaeo-Mesozoic geodynamic evolution of the Tangjia–Sumdo accretionary complex belt, which separates the North and South Lhasa Terrane, remains controversial. Moreover, the lack of geological records restricts the understanding of the evolution of the Sumdo Palaeo-Tethys Ocean from the middle Permian until the middle Triassic. Here we present zircon U–Pb geochronology, whole-rock geochemistry and Sr–Nd–Hf isotopic compositions of the Yeqing gabbro. Zircon U–Pb geochronology yields ages from 254 ± 1 to 249 ± 1 Ma. In situ Hf isotopic analyses yield ϵHf(t) values of −0.2 to +6.3. These samples have high TiO2 (3.69 wt %) and P2O5 (0.78 wt %) contents, with typical patterns like ocean island basalt (OIB). Besides, they are classified as high-Nb basalts (HNBs) based on the high content of Nb (45.3–113.5 ppm). Whole-rock Sr–Nd isotopic compositions are similar to OIB, with initial 87Sr/86Sr of 0.7047–0.7054, 143Nd/144Nd of 0.512526–0.512647 and ϵNd(t) of 0.3–2.7. These signatures suggest that the Yeqing gabbro is mainly derived from low-degree melting of the garnet lherzolite mantle. Based on field observations of HNBs intruding into the continental margin and their geochemical characteristics, we infer that the Yeqing gabbro was generated in a subduction environment. Combined with the regional geology of the subduction environment and the evolution of oceanic islands in the Sumdo Palaeo-Tethys Ocean, we propose that the Yeqing gabbro may represent a product of the asthenosphere upwelling through a slab window produced by subduction of seismic ridge in the Sumdo Palaeo-Tethys Ocean, called plume – subduction-zone interaction, during the late Permian to early Triassic.

As a hot topic in Earth sciences, the Qinghai‐Tibet Plateau has accumulated a large amount of sedimentary‐related data. We constructed a dataset of detrital components for Qinghai‐Tibet Plateau from 63 peer‐reviewed publications. The dataset thus comprises 1813 Late Proterozoic to Pleistocene sandstones from 84 stratigraphic units. For each sample, we present details on reference, detrital composition, GPS, geographic location, depositional age, tectonic setting and depositional environment. It becomes a high‐quality dataset after the information on each sandstone sample was standardized and reviewed by sedimentary experts. The dataset can be used for regional geoscience studies, exploring the general laws of the source‐to‐sink process. The dataset may also be useful in the field of utilities, such as assisting in finding suitable building stones, helping oil and gas and mineral exploration, and so forth.

Since the advent of detrital geochronology, significant progress has been made in the study of sedimentary sources. The detrital zircon U–Pb age spectrum, especially when combined with zircon Hf isotopes, provides a powerful tool for determining the provenance location, nature, and evolutionary history of sediments. The Western Qinling–Songpan tectonic junction, located in central China, is a giant structure on the crustal scale. A total of 20,640 zircon U–Pb ages of 281 sandstone samples from the Songpan–Ganzi and Western Qinling terranes were obtained. Among these, 1,636 zircons from 33 samples contained Hf isotopic data. Moreover, we compiled data on papers, samples, analytical methods, and results and obtained a total of 76 zircon U–Pb and 60 Hf isotope data heads. The obtained dataset has multiple data interfaces, which can be well associated with research or applications in different fields, for provenance analysis, climate change, and paleogeographic reconstruction studies.
