Summary: This study integrates well data, seismic data, and literature to establish a seismic stratigraphic-based sedimentary conceptual model of the Berriasian-Early Valanginian Lower Fahliyan Formation in the northwestern Persian Gulf. Three depositional sequences were identified based on facies changes, depositional geometries, and fossil assemblages. Tectonic activities and sea-level changes controlled the sedimentation of the depositional sequences. It was concluded that the Lower Fahliyan Formation was deposited in the inner to outer settings of a carbonate shelf.

Summary: Petrographic studies were conducted on the Fahliyan strata, identifying 16 microfacies and three-order depositional sequences. The results show that lower successions are associated with a sea-level fall, while middle units indicate a slight rise in sea level, and the uppermost parts represent a fall in sea level. The Mongasht section is the deepest part of the basin. By establishing a sequence stratigraphy framework, the variations in microfacies and sedimentary environment can be analyzed.

Summary: This study investigates over 3,000 m of Upper Cretaceous-Lower Palaeocene sediments in the Tarbur Formation around Shiraz city, Iran. The formation is divided into lower well-bedded rudist limestone and upper massive rudist limestone, both containing rudist particles as a major component. Various carbonate microfacies types were identified, reflecting shallow water lagoon, bar, and fore-reef palaeoenvironments. The presence of rudist fragments co-existing with a specific foraminiferal assemblage suggests a Campanian/Maastrichtian age. The distribution of microfacies in the studied area is affected by vertical displacement of basement faults.

Summary: This study focuses on the Early Cretaceous Lower Goru sand intervals in the Lower Indus Platform area. By using a third-order sequence stratigraphic framework, the depositional architecture and reservoir geometries of the Lower Goru Formation are understood. The research suggests that the Lower Goru Formation was deposited in river-dominated deltas and there may be different river lobes due to auto-cyclic switching of river distributaries. Proven reservoir intervals of the formation are concentrated in lowstand system tracts, and the net sand and porosity maps, gross depositional map, and depositional cross section provide insights into potential sandstone reservoirs and their geometries.

Summary: The carbonate-dominated successions of the Tirgan Formation in the Kopet-Dagh Basin were studied to understand the tectonic and eustatic sea-level effects and autogenic influences on facies changes and sequence stratigraphy. Fourteen facies were identified and grouped into five associations based on depositional settings. A third-order depositional sequence was identified, along with several cycles. The development of the sequences and cycles was controlled by allogenic and autogenic factors. The study provides insights into sedimentary basin evolution and paleogeographic reconstructions.

Summary: This research assesses the characteristics and depositional sequences of the Oligocene to Lower Miocene Asmari and Pabdeh formations in the Zagros Basin. Five major depositional sequences have been distinguished, showing a strong progradation system from the Zagros Simple Folded Belt towards the Persian Gulf Foreland Basin during the Rupelian period. There is likely a connection between the structural closure of the Neo-Tethys and the continuous uplift of the Zagros fold belt in the study area.

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.
