Summary: An underground utility tunnel system is planned for Xi'an, but the city is facing damage from ground fissures. The traditional cast-in-place underground utility tunnel cannot adapt well to the ground fissures activity. To reduce hazards, a physical model was used to study the stress and deformation characteristics of a prefabricated underground utility tunnel crossing active ground fissures. The analysis found that waterproof rubber is more prone to failure due to large interface tension displacement near the ground fissure.

Summary: Ground fissures, particularly in unconsolidated sediments of the Main Ethiopian Rift, are commonly caused by piping. The fissures begin with piping in linear underground voids, leading to ceiling collapse and the formation of deep fissures with vertical walls. The conditions for fissure formation include regional normal faults, extensional joints, and alternating lithological units with varying hydraulic permeability.

Summary: Late Mesozoic igneous intrusions and extensional structures in the SW Fujian region played a significant role in controlling the localization of Fe-polymetallic deposits. Extensional deformation was identified at shallow crustal levels, with normal faults associated with syn-tectonic granites. Geochemical and isotopic evidence suggest a hybrid source for the Tangquan granite, with zircon U-Pb dating indicating crystallization at around 161-159 Ma. The synchronicity of widespread granitic magmatism and polymetallic mineralization in the Late Mesozoic is likely related to extensional tectonics linked to lithospheric thinning.

Summary: Influenced by the India-Eurasia collision, the Tianshan Range and Kuqa Depression underwent multiple phases of intracontinental tectonic activation. The sediments in the Kuqa Depression recorded the basin-mountain coupling process. This study conducted detailed structural investigations, stratigraphic analysis, and detrital zircon U-Pb dating to reconstruct the uplift history of the South Tianshan Range. The results indicate that the deformation and uplift of the Tianshan Range were initiated in the Early Eocene and continued throughout the Cenozoic.

Summary: This study focused on the deformation and stress characteristics of an urban overpass crossing active ground fissures. The results showed that the soil's displacement response is concentrated near the ground fissures, and the displacement changes decrease with increasing ground fissures. Ground fissure activities redistribute the stress inside the beam and pier, resulting in the tilting of the pier. Multi-span beams can effectively reduce the influence of ground fissure activities on bridge deformation, but significant fissure activity may damage the bridge and piers. The research provides significant reference value for urban traffic planning and overpass design.

Summary: During the late Mesozoic, the North China Craton experienced three phases of intracontinental deformation in the Shangyi Basin, including NW-SE compression, NW-SE extension, and NE-SW compressional deformation. The crust in the study area underwent over 27% horizontal shortening due to the NW-SE compression, with greater contribution from the north side. These tectonic events were influenced by the subduction of the Paleo-Pacific plate, the destruction of the NCC, and the final collision between the Qiangtang and Lhasa terranes.

Summary: The study investigates the formation conditions of methane in Alpine tectonic quartz fractures using stable isotope compositions, indicating the methane is formed through advanced catagenesis of organic matter. The research suggests that the methane was trapped beneath the Alps during Mid-Miocene tectonic nappe emplacement around 25 to 15 million years ago and later released into the atmosphere during tectonic uplift around 17 to 10 million years ago.

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.
