Summary: Our research on the Trans-North China orogen has revealed the presence of a thick and refractory lithospheric mantle at approximately 1.54 Ga. This lithospheric mantle, which exhibits craton-like properties, may have been formed due to a large volume melt extraction caused by a major igneous event around 1.78 Ga. These findings are significant for understanding the evolution and stability of the Trans-North China orogen.

Summary: A study found that there are two distinct types of metasomatism in the Late Triassic syenite intrusions around the North China craton. One type is characterized by alteration of juvenile materials from subducting oceanic slabs, while the other type involves ancient materials from subduction of the South China craton. This finding demonstrates that subduction-induced metasomatism can cause heterogeneity in the subcontinental lithospheric mantle.

Summary: The study reveals that the mantle zircon megacrysts from northeastern Siberia have Triassic ages, typically formed from kimberlites or related alkaline mantle melts, and their compositions show significant variation in parental melt, potentially sourced from Triassic mantle. The chemically-heterogeneous sublithospheric source of these zircon megacrysts may have been formed through various mechanisms.

Summary: Australia's rapid plate motion and variations in the age and thickness of its continental lithosphere make it an excellent location for studying the relationship between seismic anisotropy and lithosphere-asthenosphere dynamics. This study examines shear-wave splitting data from different regions in Australia and compares it with models of lithospheric thickness and mantle flow simulations. The results show that the orientation of seismic anisotropy is influenced by both lithospheric deformation and asthenospheric flow caused by Australia's plate motion. Additionally, volcanic activity in the past has played a role in weakening the lithosphere and aiding widespread deformation.

Summary: This study aims to constrain the origins of layering in the seismic velocity structure within the cratonic mantle lithosphere. Negative Mid-Lithospheric Discontinuities (MLDs) were found to be common but intermittent, with shear velocity drops of 1%-4%. These negative MLDs are more strongly correlated with tectonic and metasomatic activity long after craton formation, rather than age-related variations in mantle composition.

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: This study provides observational support for small-scale convective rolls beneath the oceanic plates. The study found alternating upper mantle velocity anomalies aligned with gravity lineations beneath the seafloor. These anomalies, likely caused by temperature variations and possible partial melting, are strongest in deeper regions, indicating rapid vertical motions through a low-viscosity asthenospheric channel.

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: The Qingchengzi ore field is an important gold-polymetallic center of the North China Craton. The mechanical contrast between the schist and marble along lithological interfaces appears to be a major reason for stress localization under a compressional stress regime, concentrating mineralizing fluids along these interfaces. This has implications for understanding the structural controls of lithological interfaces on mineralization in other gold deposits of the region.

Summary: The dark enclaves in the late Paleocene granitoids of Doumer Island have similar ages and isotopic compositions to their host rocks, indicating a cogenetic relationship. These enclaves are either cognate restites resulting from dehydration melting or fragments of chilled conduit margins entrained in later intrusive magmas. The presence of certain minerals and patterns in the enclaves suggest specific processes of magma formation and evolution within the granitoids.

Summary: This study presents paleomagnetic data from the South Shetland Islands, providing valuable constraints on the paleoposition of the Western domain of the Antarctic Peninsula. The data suggests that the South Shetland Islands experienced southward translation and rotation during 100-90 Ma, with a direct affinity to the southern Patagonia-Fuegian Andes. The consistent Cretaceous paleomagnetic declination in the Antarctic Peninsula supports an autochthonous continental subduction model, indicating a near-synchronous tectonic-magmatic history between the Antarctic Peninsula and the southern Patagonia-Fuegian Andes.

Summary: The Proterozoic period played a crucial role in the transition of Earth's tectonic regimes, atmosphere-ocean environments, and biological evolution. Research on Proterozoic large igneous provinces (LIPs) and black shale deposition can aid in reconstructing paleogeographic locations of different cratons. It has also been shown that Proterozoic LIPs have significant environmental effects, such as the initiation of the Great Oxidation Event and the formation of black shales.

Summary: The Diabase sills in the northern North China Craton (NCC) represent a large igneous province (Yanliao LIP) extending over 600 km. The newly identified dolerite dyke in the Liaodong Peninsula reveals an eastward extension of the Yanliao LIP, supporting the close connection between the NCC and the NAC. The geochemical data of the dyke suggests derivation from a metasomatized subcontinental lithospheric mantle with insignificant crustal contamination.

Summary: A large-scale continental rift zone dating back to 1.4-1.3 billion years ago has been identified along western Laurentia, western-northern Siberia, southeastern Baltica, western-northern West Africa, southwestern Amazonia, southern-eastern Congo/Sao Francisco, eastern Kalahari, northern North China, and northern North Australia. This rift zone, extending approximately 15,000 km across the supercontinent Columbia, played a significant role in its breakup. The spatial distribution of REE deposits associated with carbonatite intrusions further supports the importance of this rift system in controlling the formation of major rare earth element deposits.

Summary: In this study, new zircon U-Pb ages, whole-rock major and trace element compositions, Li and zircon Hf isotopic compositions, and oxygen fugacity of the late Palaeozoic continental-arc magmatic rocks in the Gongzhuling area were determined to identify the source region and origin of the magmas. The dioritic rocks were formed through mixing processes, with the mafic melts originating from a metasomatized mantle wedge and the felsic melts from the lower crust of a Neoproterozoic arc. The redox conditions of the magmas preclude large-scale porphyry Cu-Mo mineralization.

Summary: The Ectasion Period (1400-1200 Ma) represents a transition stage from Columbia to Rodinia supercontinents. Mafic rocks in the Fanhe basin around 1.23-1.21 Ga showed distinct trace element and Nd isotopic compositions, possibly derived from asthenospheric mantle and subduction-modified subcontinental lithospheric mantle.

Summary: Plate reconstructions of the Antarctic Peninsula show its rotation and spatio-temporal history of magmatism since 90 Ma, using a combination of paleomagnetic data and geological evidence. It is found that the convergence variation between the Phoenix Plate and Antarctic Peninsula, as well as the back-arc extension of the Scotia Plate, correlate with five different plate rotation periods. The initiation of the South Sandwich subduction zone and the separation between the Antarctic Peninsula and South America can be explained by clockwise rotation of the Antarctic Peninsula starting at around 80 and 62 Ma, respectively.

Summary: Through our study of the western part of the North China Craton, we found that the formation of the Bayan Obo deposit occurred during the late Paleozoic when there was an unusually high temperature in the upper crust. This high temperature resulted in extensive thermal perturbations and recrystallization of REE-bearing minerals, as well as the resetting of isotopic clocks. These findings are important for understanding the genesis and timing of the Bayan Obo deposit.

Summary: The newly confirmed Palaeoproterozoic successions in the Fanhe Basin of the North China Craton (NCC) contain carbonates with high positive carbon isotope excursion, indicating the presence of the Lomagundi-Jatuli Event (LJE) in the NCC. The carbonates deposited before 2.06 Ga have positive carbon isotope, while those deposited after have normal carbon isotope. The carbonates from the Daposhan Formation have the largest positive carbon isotope excursion in the NCC. The carbon isotope values of the carbonates in the Fanhe Basin exhibit a decreasing trend from approximately 2.20 Ga to 2.06 Ga, similar to contemporaneously deposited carbonates in other cratons.

Summary: Comparisons of large igneous provinces (LIPs) and black shales from different cratons provide important constraints for paleogeographic reconstructions and understanding the environmental effects of volcanic events. The North China Craton (NCC) and North Australian Craton (NAC) show good correlation in LIP ages from 1800 Ma to 1300 Ma, and further evidence of connection is found in the comparison of black shales. However, subsequent to 1300 Ma, the two cratons exhibit different magmatic histories, indicating their separation. The results suggest a long-lived connection between the NCC and NAC from 1800 Ma to 1300 Ma, lasting for at least 500 million years.

Summary: This study investigates the zircon ages and whole-rock geochemical data of Late Paleozoic magmatic rocks in the Western Yunnan Tethyan belt to identify the origin and mechanism of mantle melting. The results suggest that these magmatic rocks may originate from different mantle domains that were metasomatized by slab-derived fluids and sediment-derived melts.
