Summary: The study finds that the conductors in different regions of the North China Craton can be attributed to different tectonic mechanisms, including oceanic subduction, ancient suture zones, and modern craton destruction. In addition, anisotropy is observed in the lower crust and uppermost mantle of the southern part of the North China Plain, with enhanced conductivity along a specific direction, which may be related to magma accumulation caused by Cenozoic asthenosphere upwelling.

Summary: By studying the thermoelastic properties of minerals in mantle xenoliths combined with their thermal states, we can gain a comprehensive understanding of the petrophysics of the lithospheric mantle. High-pressure and high-temperature experiments on main minerals from peridotite xenoliths in the eastern North China Craton revealed changes in density profiles during the destruction process since the Mesozoic, indicating lateral heterogeneities.

Summary: The Late Triassic mafic dykes in Eastern Hebei were emplaced between 238 and 223 Ma, resulting from partial melting of ancient lithospheric mantle. These magmatic activities are related to the onset of lithospheric thinning of the North China Craton, likely caused by post-collisional extension after subduction and collision events.

Summary: Previously collected magnetotelluric data were used to create an improved 3D resistivity model of the Slave craton lithosphere. A low resistivity region was identified beneath the central Slave craton, known as the Central Slave Mantle Conductor (CSMC). The CSMC was previously interpreted as graphite films, but new analysis suggests alternative conduction mechanisms such as metasomatic phlogopite, grain boundary sulphides, and high density fluids including hydrous carbonatite melts or brines. Brines are preferred as they explain geophysical observations and are observed in fibrous diamonds coincident with the CSMC.

Summary: The Ordos Block, located on the western edge of the North China Block, is characterized by high effective elastic thickness (Te) values, indicating strong rigidity. In contrast, the mechanical strength of the south-west margin, especially the Baryan-Har Block and western Qinling Block, is mainly supported by the brittle upper crust, resulting in lower Te values.

Summary: The study focused on seismic anisotropy around the Ordos Block, finding that the central and eastern regions have a relatively thick and rigid lithosphere, while the western lithosphere may have undergone significant deformation due to expansion and compression of the Tibetan Plateau. Anisotropy near the Datong Basin is related to the compression direction of the Tibetan Plateau, while the central part of the Shanxi Rift shows weaker anisotropy.

Summary: The North China Craton experienced extensive crustal reworking during the Mesozoic, with the decratonization processes not well understood. This study used zircon Eu/Eu* ratios to reconstruct crustal thickness and investigate the decratonization processes in the Jiaodong area. The results suggest crustal thickening from the Late Jurassic to around 130 Ma due to westward subduction of the Paleo-Pacific slab, followed by a slow thinning process from 130 to 110 Ma possibly caused by chemical erosion induced by slab rollback and asthenosphere upwelling.

Summary: The mantle lithosphere beneath the North China Craton underwent significant transformations from the Paleozoic to the Cenozoic, with changes in thickness, composition, and isotopic signature. The destruction of the craton was influenced by Paleozoic subductions and Mesozoic dynamic processes like mechanical intrusion, melt fluid erosion, and local delamination, leading to lithospheric thinning and extension.

Summary: This study presents a method to reconstruct the Paleozoic-lithospheric structures of the North China Craton (NCC) and reveals that there was massive thinning in the eastern East Block (EB) after the Paleozoic, while thickening occurred in the northern Ordos Basin and the region from the Weibei uplift to the South Taihang Mountains uplift. The calculated self-sustaining oscillation periods are in good agreement with the periodicity observed in the sedimentation rate of the Ordos Basin and basaltic underplating events in the Trans-North China Orogen. The results suggest that, apart from the EB, the Phanerozoic lithospheric modification of the NCC is mainly controlled by heat conduction and dissipation through the cratonic lithosphere.

Summary: By inverting new data and combining with independent geochemical data, this study reveals the detailed thermal and compositional structures beneath northeast China, demonstrating the presence of regions of partial melting in the mantle. It is found that the generation, location, and composition of intraplate volcanism in this region are controlled by the interaction between shallow asthenospheric circulation and lithospheric thickness. The modeling approach and correlations identified in this study are globally applicable for assessing mantle conditions over time in other continental regions.

Summary: In this study, we used P and S receiver functions to obtain the crustal and lithospheric structures of the Ordos block in the western North China Craton. The results show that the Ordos block has a thick lithosphere, while the lithosphere is significantly thinner in its surrounding rift systems. Furthermore, the northern margin of the Ordos block is heavily modified by mantle upwelling, whereas the southern margin has little modification from eastward lateral asthenospheric flow.

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 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.
