Summary: This study analyzed the source areas and transport modes of Lower Jurassic sediments on the South China continental margin, and found that the distribution system was significantly influenced by Paleo-Pacific subduction. Different regions had distinct primary source areas, with the central region being a vast shallow sea in the Early Jurassic due to large-scale transgression.

Summary: The Upper Triassic to lowest Upper Jurassic strata in north-eastern Mexico record surface processes during the early rifting that led to the opening of the Gulf of Mexico. This study uses detrital zircon U-Pb ages and clast compositions to constrain depositional ages and reconstruct tectonic setting and provenance, indicating deposition in partitioned rift basins receiving sediment from local sources within a distance of approximately 100 km. These data contribute to understanding surface processes during the initial rifting that eventually led to the opening of the Gulf of Mexico.

Summary: By using detrital zircon U-Pb dating and composition statistics, this study constrained the maximum depositional age and provenance of the Xiazijie fan-delta in the Triassic Baikouquan Formation. The results showed that the fan-delta was deposited between the late Permian and early Triassic, with the major source area being the central West Junggar Yangtze continental arc and the Hakedun-Hongguleleng area. This research has significant implications for stratigraphic correlation in the Junggar Basin and hydrocarbon exploration in the Xiazijie fan-delta conglomerate reservoir.

Summary: The Shingai Unit in the Kurosegawa Belt is subdivided into sedimentary zone and melange zone, with sandstones of varying compositions. Detrital zircon ages suggest an Early Triassic depositional age and a change in provenance from basement rocks to volcanic arc. This provenance change supports progressive denudation of the volcanic arc, with similarities in provenance found in upper Permian-Lower Triassic strata in neighboring belts. The sedimentary environment is inferred to have been a trench and shelf adjacent to an isolated island arc.

Summary: This study presents new detrital zircon U-Pb and Lu-Hf isotopic data to reveal the evolution of the Qiangtang terrane and the tectonic affinity of its subterranes. The detrital zircons from the North Qiangtang subterranes were likely derived from arc magmatic rocks associated with the subduction of the Paleo-Tethys oceanic lithosphere, while those from the South Qiangtang subterranes show similarities with other terranes such as South Qiangtang, Lhasa, Himalaya, and the Indian Gondwana. The North and South Qiangtang subterranes originated from the Yangtze block and Gondwana, respectively, and the northward subduction of the Paleo-Tethys oceanic lithosphere continued at least until the Late Devonian to Triassic.

Summary: The Cenozoic deformation of the Tianshan Mountain Range and its impact on the Tarim Basin's exhumation and topographic growth are investigated in this study through the analysis of detrital apatite fission-track ages. The results show major age-shifts at -23 Ma and -10 Ma, suggesting drainage reorganizations associated with the uplift of the South Tianshan Mountain Range. The progressive topographic growth of the range is found to have influenced the aridification of the Tarim region.

Summary: The Early Permian bauxite in the Sichuan Basin is a part of karst-type bauxite deposits in South China Block and its provenance is poorly understood. This study used mineralogy, geochemistry, detrital zircon U-Pb ages, and trace element compositions to determine the provenance of the bauxitic claystone. The results suggest that the bauxitic claystone has mixed sources, with the siltstone from the Lower Silurian Hanjiadian Formation being the dominant source and Late Paleoproterozoic magmatic rocks along the western margin of the Yangtze Block being the secondary source. The source materials of the Han-jiadian Formation siltstone are mainly from Grenville-aged magmatic rocks in the Cathaysia Block and Neoproterozoic magmatic rocks in the Jiangnan orogen.

Summary: Detrital zircon U-Pb age determination using HR-SIMS was conducted to determine the maximum depositional age of the Ullyeonsan Formation in the Yeongyang Subbasin, southeast Korea. The detrital zircons from the Ullyeonsan Formation show diverse ages from Archean to early Cretaceous, indicating sedimentation from adjacent areas with exposed source rocks. The youngest detrital zircon cluster yielded a concordia age of 110.4 ± 2.5 Ma, suggesting the maximum depositional age and a correlation with the deposition of the Hayang Group in other subbasins of the Gyeongsang Basin.

Summary: This study investigates the tectonic evolution and provenance characteristics of the late Paleozoic to early Mesozoic collision-related orogeny in Japan using morphological analysis and U-Pb ages of detrital zircons. The results show that the late Paleozoic zircons were derived from nearby sources, while the pre-late Paleozoic zircons were supplied from distant sources under strong hydrodynamic conditions. Combining the geological information of East Asia, the study reveals a change in sources from the Southern zone of the Maizuru Belt to multiple areas, supporting the collision of the island arc and continental margin of the Sino-Korean Block during the middle Permian.

Summary: The M 6.5 earthquake near Mina, Nevada on May 15, 2020 was well-documented with seismic and geodetic instrumentation, allowing for detailed analysis of the surface rupture. Integration of multiple datasets revealed educational and research opportunities, with models for slip at depth consistent with various data sources. The earthquake also suggests new seismic hazard assessment approaches may be needed for rapidly evolving tectonic regions.

Summary: The compositional similarity between high-Mg andesite-dacite from accretionary orogens and bulk continental crust provides an opportunity to unravel the CC formation paradox. Compositional data from a global compilation of Quaternary magmatic arcs indicate the presence of low-Mg series and high-Mg series. The LMS show trends of crystal fractionation, while the HMS have mixed compositions that can be explained by partial melting of melange diapirs rising into the mantle wedge.

Summary: The Early to Middle Jurassic stratigraphic sequences of the Sanandaj-Sirjan Zone in Iran and the Sakarya Zone in Turkey, which exhibit similar features, suggest that they formed in a common tectonic setting of an extensional basin. The whole-rock chemistry and Sr-Nd isotope signatures indicate that the mafic melts originated from partial melting of the subcontinental lithosphere. The decompression associated with extension led to the partial melting of spinel-garnet lherzolite and formation of tholeiitic to transitional basaltic magma. The inversion of extensional basins occurred during the Mid-Late Jurassic.
