Summary: The assessment of detrital zircon age records in basin analysis is prone to biases caused by high to ultrahigh temperature (HT-UHT) metamorphism, which can disturb the U-Pb zircon system and result in protracted age distributions. This study re-evaluates geochronological data on HT-UHT metamorphic rocks from different eras to demonstrate the unclear geological meaning of their age distributions. To overcome this bias, a workflow combining multi-proxy approaches and petrochronological investigation is proposed. It allows for the appraisal of biases imposed by HT-UHT metamorphism in the U-Pb detrital zircon record and suggests ways to overcome these issues.

Summary: By analyzing the U-Pb ages of detrital monazite from Cambrian sedimentary rocks, we suggest that South China was located outboard of northeastern India. The detrital monazite ages indicate input from earliest Cambrian metapelites and provide tighter constraints on the paleogeography of South China compared to detrital zircon data alone.

Summary: Zircon U-Pb geochronology is crucial for calibrating the geologic timescale. This study found that zircon grains in the Brockman Iron Formation yielded ages younger than the host sedimentary rock. In situ U-Pb dating techniques were used to directly analyze zircon crystals, and the results were consistent with independent age constraints. The study also discovered that young zircon dates could be attributed to hydrothermal alteration.

Summary: Through the study of whole-rock geochemistry, detrital zircon U-Pb-Hf isotopes, and trace element data from Mesoarchean clastic rocks in two greenstone belts of the western Dharwar Craton, it is found that these rocks were derived from a strongly weathered stable continental provenance dominated by low-HREE TTGs and K-rich granites of shallow crustal origin. The detrital zircon U-Pb and Lu-Hf data indicate two major crust formation events, with the antiquity of the western Dharwar Craton traced back to at least 3.8 Ga. The detrital record suggests episodic crustal growth and reworking in the western Dharwar Craton during the Paleoarchean to early Mesoarchean period, possibly related to intraplate processes.

Summary: The provenance and tectonic implications of Late Paleozoic sedimentary rocks in the South Qinling Belt (SQB) indicate the timing and mechanism of the collision between North China Block (NCB) and South China Block (SCB). New LA-ICP-MS zircon U-Pb ages and geochemical composition of metasedimentary rocks from the Foping area in the SQB were reported. The results show that the previously-assumed Neoarchaean or Paleoproterozoic strata were actually deposited in the Late Paleozoic.

Summary: The study of the Qamdo basin reveals a tectonic setting characterized by a continental island arc, with lower weathering degree compared to the Lanping-Simao area, suggesting a closer proximity to the original source. Detrital zircon age distribution indicates a provenance from the Qiangtang Block, Youjiang basin, and Yangtze area for the basin, which may have been part of a larger marine basin before evaporite deposition. Metamorphic seawater from the Qamdo basin could have migrated to the Lanping-Simao basin and the Khorat basin for evaporite deposition.

Summary: Graphitic carbon nitride (g-C3N4) has been widely used due to its excellent optical properties and physicochemical stability. The risk of g-C3N4 transport in the environment has been overlooked, but this study investigated its transport behavior in various media. The results showed that flow rate and ionic strength influenced the transport, and the presence of lead (Pb) affected the outflow of g-C3N4. The unique structure of g-C3N4 particles allowed them to deposit in certain media and act as carriers for Pb release.

Summary: Magmatic-hydrothermal systems play a crucial role in transporting materials and potentially affecting Earth's long-term environment. This study investigates the duration of prograde metamorphism induced by fluid infiltration and the amount of carbon released by skarn ore deposits. The findings reveal that skarn ore deposits can efficiently decarbonize CO2 at a high rate, surpassing volcanism in different tectonic settings. The CO2 flux of skarn deposits increases over time and reaches a maximum value at the J/K boundary, providing an important previously unquantified source of outgassing in the subduction zone.

Summary: This study investigates the seismic structure of the Eastern European lithosphere and the transition from Precambrian to Phanerozoic Europe. The results show that the crust thickens across the Trans European Suture Zone boundary and the mantle is seismically faster beneath younger terranes. The Precambrian building blocks exhibit contrasting seismic fabrics, with the Baltic orogens characterized by uniform crust and the Sarmatia region showing alternating high and low velocity layers.

Summary: This study analyzes the U-Pb-Hf-O isotopes of zircons in felsic granulite xenoliths from the Fuxin late Cretaceous basalts in the North China Craton to evaluate the role of magma underplating in modifying the Archean lower crust. The results show that long-lived magma underplating occurred beneath the Fuxin region during the Mesozoic, with underplated magmas originating from the lithospheric mantle and later from the depleted asthenospheric mantle. This study concludes that magma underplating not only provided heat for remelting, but also added exotic material and weakened the lower crust, leading to its destruction.

Summary: This study investigates two volcanic provinces in the western branch of the East African Rift and finds that the volcanic products show wide variability in chemical and mineralogical characteristics. Petrographic and geochemical analysis reveals enriched and heterogeneous sub-lithospheric mantle sources. The differences in isotopic features between the two volcanic provinces may indicate changes in the composition, mineralogy, and depth of melting in the lithospheric mantle source.
