Summary: The study shows that the core of intraplate faults is wider while plate boundary faults are narrower, regardless of total displacement. Plate boundary fault earthquakes typically have a greater seismic moment compared to intraplate events with the same value of displacement. Narrow plate boundary faults dissipate less energy during earthquakes, leading to higher magnitude earthquakes due to more energy being radiated to the surface.

Summary: The near-trench coseismic rupture behavior of the 2011 Tohoku-Oki earthquake is poorly understood due to lack of near-field observations. This study used differential bathymetry estimates with improved horizontal resolutions to investigate the near-trench coseismic slip behaviors. The results revealed a velocity-strengthening behavior in the shallow fault and significant off-fault deformation features near the backstop interface outcrop.

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.
