Summary: The Lomagundi-Jatuli Excursion (LJE) in the early to mid-Paleoproterozoic era is the largest and longest positive carbon isotope excursion recorded in carbonate rocks in Earth history. Its genesis, synchrony, global-versus-local extent, and role in atmospheric oxygenation are still subjects of debate. Reviewing existing models and data, this study questions the interpretation of the LJE as a globally synchronous event and suggests that any model for the LJE needs to account for its undefined initiation and termination and facies-dependent expression.

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: This study investigates and reviews the strata and igneous suites in the eastern North China craton during the late stage of the Great Oxidation Event (GOE) known as the Lomagundi-Jatuli event (LJE). The results show that the LJE-traced strata span approximately 200 Ma and are correlated with the emplacement of large igneous provinces (LIPs) during a global LIP peak. These LIPs contribute to the accumulation of organic matters in sediments and the oxygenation of the atmosphere through subaqueous-extrusions and nutrient elements' input. The termination of the GOE-LJE is associated with the emergence of subduction systems and orogenic processes.

Summary: The Lomagundi (-Jatuli) event, which occurred approximately 2.2 billion years ago, is significant for understanding the causes and consequences of the great oxygenation event, carbon storage and sequestration on Earth's surface, evolution of life, and the influence of tectonic activities on the environment. This study reports the discovery of meta-carbonate rocks with distinct positive carbon isotopic excursion from the Paleoproterozoic continental collision zone of the Kongling Complex in South China Craton. The findings suggest that the burial of 12C-enriched organic carbon during the oceanic closure resulted in the global enrichment of 13C in atmospheric CO2, recorded in marine carbonate rocks. The study also highlights the role of orogenesis in carbon sequestration into the continental crust.

Summary: This study focuses on the carbon and oxygen isotopes and trace element geochemical data of the Paleoproterozoic marble deposits of the Jingshan Group in the Jiaolai Basin of the Jiaodong Peninsula, eastern China. The findings suggest that the marble deposits underwent recrystallization, metamorphism, and silicification, resulting in a significant positive 13C anomaly, possibly reflecting the global Lomagundi-Jatuli event. The geochemical analysis of rare earth and other trace elements indicates that the banded iron formation deposits associated with the Jingshan Group formed in a redox stratified ocean dominated by ferruginous conditions. Furthermore, the positive carbon isotope anomaly associated with the Lomagundi-Jatuli event is predominantly found in sediment deposited in shallow and coastal marine environments.

Summary: This study investigates the marine shales deposited during the Lomagundi Event in the Paleoproterozoic era, providing evidence for a highly productive and well-oxygenated photic zone. However, a subsequent deoxygenation of the atmosphere-ocean system led to enhanced denitrification and reduction of selenium oxyanions. The findings suggest that oxygen levels in the atmosphere-ocean system during this period were much lower than modern concentrations.

Summary: Based on the study of mafic dykes in Jiaodong, it is found that the nature of lithosphere mantle beneath NCC has changed during the Mesozoic. The Kunyushan dyke originated from an old and enriched lithosphere mantle source, while the Nansu dyke sourced from an enriched MORB mantle and was generated by fluid flux melting.

Summary: The study reveals that Mesozoic mafic dykes in the North China Craton (NCC) are associated with gold deposits. These dykes were emplaced in two episodes at 219-227 Ma and 121-137 Ma, with potential sources ranging from convective asthenospheric mantle to ancient lithospheric mantle. The geochemical and isotopic characteristics suggest a possible link between the dykes and gold mineralization, possibly related to tectonic extension associated with Pacific slab subduction.

Summary: The period around 2.5 billion years ago marked a significant event in the evolution of Earth's continental crust, particularly in the North China Craton where seven micro-blocks formed within greenstone belts. The rocks in the NCC from this time suggest that the micro-blocks amalgamated to form the craton through a process of high-grade metamorphism and partial melting. This cratonization event had global significance and led to the stabilization of supercratons or cratonic groups on a global scale.

Summary: This study focuses on trondhjemite xenoliths from the Kongling Complex in South China, confirming their hybrid features with mafic dykes of the same age, as well as the variations in remnant pressure of apatites in zircon hosts. The results suggest a widespread and locally thick trondhjemitic crust in the Yangtze Craton during the Mesoarchean period.

Summary: This study reveals the significant role of deep-seated fluids and metals in the formation of large-scale gold deposits in eastern China. By analyzing trace elements and sulfur isotopes in granite, it is found that mafic enclaves played a crucial role in transporting ore-forming materials. The study suggests that gold and ore-related components were transported from the deep mantle to the shallow crustal levels through magma mixing.

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 article reviews the processes that led to the current geological timescale and proposes revisions for subdividing time before 720 million years ago. The assessment of Precambrian rock records suggests that using rock-based concepts for subdivision may require only modest deviation from current chronometric boundaries.

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: 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.
