Summary: The study of early Carboniferous volcanic rocks in the Junggar Basin, NW China, reveals a bimodal suite of rocks dominated by basaltic and felsic rocks, possibly formed in a localized back-arc extension setting. The mafic rocks show arc-like trace-element distribution patterns, while the felsic rocks are geochemically equivalent to A(2)-type granite, indicating a derivation from the mafic magma by fractional crystallization.

Summary: By integrating potential field analysis with geological and geochemical data, new insights into the crustal structure and evolution of the Mongolian collage are gained. The inconsistency between geologically defined terranes and geophysical domains in the southwestern part of the Mongolian collage is demonstrated by magnetic and gravity data. The homogeneous lower crust composed of felsic to intermediate juvenile material beneath a geophysically heterogeneous upper crust is interpreted as a result of a trench-directed lower crustal emplacement of an arc type crust underplating deformed Paleozoic oceanic crust.

Summary: The study of the Dunhuang Orogenic Belt (DOB) in Central Asia reveals Permian-Triassic magmatic and thermal records that possibly lasted until the Middle Triassic, indicating a final subduction of the Paleo-Asia Ocean (PAO) in the DOB. The magmatic rocks show continental arc-related geochemical features and the zircon ages suggest a melting of ancient crustal materials. The high heat flow setting during this period was possibly triggered by arc activities.

Summary: This study reveals that the Yanshanian-Himalayan tectonic activity affected the deformation and hydrocarbon accumulation in the northwestern Junggar Basin. The deformation process during the Yanshanian orogeny formed a fault system that connected with the Permian-Triassic oil-gas system, resulting in the formation of fault-controlled reservoirs. The deactivation of this fault system during the Himalayan orogeny, along with reservoir densification, created favorable conditions for oil preservation and accumulation.

Summary: The Early Carboniferous volcanic and intrusive rocks found in the Mayile area of West Junggar, northwestern China, are typical subduction-zone island-arc magma, characterized by enrichment in light rare-earth elements and large-ion lithophile elements, and depletion in heavy rare-earth elements and high-field-strength elements. This suggests that extensive intra-oceanic arc magmatism occurred in West Junggar during the Early Carboniferous period.

Summary: This study provides systematic geochemical and geochronological research of well-preserved drill cores from the Piedmont of the Hala'alate Mountain in West Junggar. The results show that the Late Carboniferous rocks belong to the A-type granite series and arc-affinity geochemical compositions, indicating a partial melting of juvenile continental materials and a modified pyroxene-rich mantle source. The tectonic processes of West Junggar during the Carboniferous to Early Permian can be divided into three stages: sustained subduction processes, closure of the oceanic crust and collision orogenesis, and post-collision extension setting.

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.
