Summary: This study presents a compilation of zircon U-Pb age and Hf isotopic data from the granitoids in the Alxa area. The results show that the granitoids in the central Alxa area have juvenile isotopic features, while the granitoids in the western Alxa area have ancient isotopic features. Based on these findings, it is inferred that there is a boundary between the North China Craton and the Central Alxa Orogenic Belt in the Alxa area.

Summary: The discovery of zircon xenocrysts with new U-Pb ages confirms the existence of 3.85 Ga crustal precursors below the southern North China Craton and rules out the possibility of lateral transport. The inherited zircon age groups suggest that the southern North China Craton has experienced global supercontinent events, revealing the geological evolution of the region.

Summary: The study of the Southern Jilin Complex using high-precision in-situ zircon U-Pb-Hf-O isotopes reveals three episodes of magmatism at around 2.78, 2.69, and 2.55 billion years ago, with magma sources mainly derived from crustal reworking and minimal sediment recycling. The findings suggest a bottom-up geodynamic regime in the region during the Neoarchean, possibly related to plume activities, rather than involving modern-style subduction.

Summary: The study provides important insights into the geological evolution of the Alxa Block in the westernmost part of the North China Craton. The analysis of the Diebusige Metamorphic Complex reveals the existence of Archean rocks and indicates late Neoarchean to Paleoproterozoic metamorphic events in the area. The data also suggest that the main part of the complex may have been formed around 2.1-2.0 Ga and originated from the reworking of ancient Archean crust. The findings further suggest that the Langshan area had an independent terrain history before the middle Paleoproterozoic.

Summary: This study provides evidence on the formation and evolution of the Ordos Block through the analysis of detrital zircons from the sandstones of the Changcheng System. The results indicate that the Ordos Block was mainly formed in the early Neoarchean and underwent three strong tectonothermal events at 2.5-2.4 Ga, 2.2-2.0 Ga, and 1.95-1.8 Ga, which were associated with peripheral orogenic belts.

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: This study investigates the genesis of Pb-Zn mineralization in the Ningi-Burra region in Nigeria, combining geochemical and geochronological data of magmatic and hydrothermal processes. The findings suggest that the mineralization mainly occurs in highly evolved granites, accompanied by silicification, chloritization, and limited metasomatism. Isotopic analysis of zircon indicates a magmatic source for the hydrothermal fluids involved in the formation of mineralization, highlighting the importance of U-Th-Hf isotopes as robust tools for constraining magmatic and mineralization processes in differentiated granites.

Summary: This study analyzes samples from the Pilbara Craton in Western Australia and finds a connection between mantle and crustal processes throughout the craton's history. The evolution of the craton was mainly driven by the transformation of juvenile mantle materials into felsic igneous rocks, indicating sustained continental growth over the past 4 billion years. The collision of the East and West Pilbara terranes at 3.1 billion years ago increased the involvement of older crust in magma generation. This study highlights the importance of comparing mantle and crustal isotope records to understand crustal growth rates in ancient terranes.

Summary: Northern Xinjiang in China is an important part of the Central Asian Orogenic Belt, characterized by multiple episodes and types of mineralization. Cu and Au deposits are mostly found in Altay, Junggar, and Tianshan, with minor occurrences in Beishan. The most common types of Cu-Au deposits are volcanogenic and porphyry deposits. The formation of Cu-Au deposits can be divided into five mineralization episodes, with the Devonian and Carboniferous being the main periods. These deposits developed in various tectonic settings, including island arc, continental arc, collision, and postcollisional extensional tectonics.

Summary: Numerous lode gold and silver deposits have been discovered in orogenic belts in China. This study focuses on the formation and fluid evolutions of the super-large Yingdongpo gold and giant Poshan silver deposits in the Tongbai-Dabie orogen. The results suggest that both deposits were formed concurrently with Early Cretaceous granitic magmatism and the ore-forming fluids were primarily of magmatic origin with meteoric water inputting. The gold mineralization is related to a change in the physicochemical properties of the fluids, while the silver mineralization is favored by progressive deposition of sulfides in a slowly cooling hydrothermal system.

Summary: The Brahmaputra foreland basin, known for its dynamic tectonism and sediment load, exhibits a variety of seismically generated soft sediment deformation structures (SSDS) such as clastic dikes, sand sills, and micro-faults. These structures, influenced by multiple strong seismic events, are characterized by their dimensions, intrusion angles, cross-cutting relations, wall shattering, and age. The study suggests that a significant earthquake with high intensity and magnitude might have caused liquefaction features in the area. The findings highlight the importance of studying SSDS in tectonically active regions with limited surface ruptures and dense alluvial cover.

Summary: The extensively developed Early Cretaceous intermediate-felsic rocks in the northern North China Craton provide valuable insights into the nature of Paleo-Pacific subduction and associated geodynamic processes. Geochemical and geochronological analyses of trachyandesites and rhyolites from the eastern Hebei, northern NCC suggest that the trachyandesites likely originated from enriched mafic lower crust and the rhyolites are derived from the trachyandesitic magmas through fractional crystallization. The migration direction change of these rocks is believed to be primarily attributed to slab rollback of the subducting Paleo-Pacific Plate.

Summary: The organic-rich shales of the Shuijingtuo Formation in China are an important target for shale gas exploration. The upper section of the formation, primarily consisting of limestone, silty shale, and black shale, has been rarely studied but recently showed promising results for shale gas exploration. Geochemical investigations of the upper section shale deposits revealed that the organic matter enrichment mechanism underwent dynamic changes due to relative sea-level changes and episodic upwelling activities.

Summary: This study analyzed the heterogeneity of gas compositions and the effects of magmatism on gas accumulation in shale gas exploration in the Yangtze plate. The results showed that magmatism caused the development of micro-fractures in shale reservoirs and accelerated the thermal evolution rate of organic matter. The impact of magmatism on shale gas accumulation varied in different regions, either favoring or compromising efficient gas accumulation in shale reservoirs.
