Summary: This study aims to develop criteria to differentiate mixed, along-slope-, and down-slope-generated elements from other deep-water deposits based on bathymetric, seismic and sediment core data. The study reveals that the persistence of bottom currents and the variations in turbidity flows affect the morphology and development of sediments. Interactions between along-slope and down-slope processes can be synchronous, asynchronous, or passive. The evolution of mixed systems is influenced by various factors such as confinement, sediment supply, and climatic fluctuations. Mixed systems feature complex geometries and may become important targets for energy geosciences and other research fields.

Summary: The Portwood Member of the New Albany Formation is a dolomitic black shale succession deposited in the western Appalachian Basin, consisting of three erosion-bounded stratal packages recording Late Givetian eustatic sea-level variations. Detailed petrographic study and thin section based microfacies analysis shed light on depositional setting and history, identifying multiple sedimentary settings and enabling subdivision into a series of upwards shallowing parasequences. Understanding shale hosted carbonate intervals through petrographic due diligence provides a sophisticated understanding of depositional conditions and long-term trends.

Summary: This study establishes the absolute age and boundaries of the Miocene sequences in Iraq for the first time using high-resolution cyclostratigraphic analysis. The research also identifies 16 unique carbonate and evaporite facies types and suggests that sea-level change was the dominant regulator of lower Miocene deposition. Additionally, a sharp sediment accumulation rate was found due to an abrupt shift in the depositional environment.

Summary: A regional sequence-stratigraphic framework is proposed for the Berriasian-Barremian shallow platform succession in the Zagros Fold-Thrust Belt, supported by biostratigraphic results and calibrated by Sr-isotope data. Four large-scale sequences and sixteen small-scale sequences were identified and described, representing different depositional environments and platform growth architectures in different stages of the Berriasian-Barremian succession.

Summary: This study presents a new stratigraphic framework for the Adi.yaman Group, investigating lithostratigraphy, biostratigraphy, microfacies analysis and sequence stratigraphy. The group ranges in age from late Santonian to early late Campanian and was deposited in environments ranging from deep shelf to lagoonal. Sequence stratigraphic studies identified three third-order depositional sequences, separated by sequence stratigraphic surfaces.

Summary: This study analyzes the depositional and stratigraphic architecture of Mississippian reservoirs in the Anadarko Basin using modern geologic datasets. The study reveals the depositional evolution from carbonate deposition to mixed carbonate-siliciclastic deposition, documenting marine transgression, stabilization, progradation, and transition to siliciclastic deposition. The reservoir architecture changes from proximal carbonate facies to storm-dominated ramp margin conditions, and finally to siliciclastic facies.

Summary: This study contributes to the reconstruction of the palaeoenvironment of the Zagros Basin during the Furongian period through high-resolution facies and microfacies analysis. The analysis identified six facies associations representing different settings of a mixed carbonate-siliciclastic ramp and revealed five medium-scale transgressive-regressive cycles and larger-scale sequences. The findings provide new constraints for the lower Palaeozoic evolution of the north-eastern Gondwana.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.

Summary: This study investigates 13 submarine seamounts in the southern Andaman volcanic arc and observes evidence of hydrothermal activity in one of the seamounts. The evidence includes plumes rich in dissolved gases, live chemosymbiotic organisms, and the deposition of neoforming minerals. These observations suggest the development of a new hydrothermal field in the least explored Andaman Sea.

Summary: This study employs an integrated depositional and sequence stratigraphic approach to assess the control of diagenesis on reservoir porosity of a hybrid-energy delta system. The study focuses on the Barik Formation in the Haushi-Huqf region of Central Oman, which represents a highstand system tract of a hybrid-energy delta. The assessments reveal that the reservoir porosity is controlled by various degrees of diagenetic processes, including mechanically infiltrated clays and kaolinitization of silicate grains.

Summary: Oilfield brines are a significant alternative lithium resource. This study investigates the metallogenic characteristics and enrichment process of oilfield brines from the Jianghan Basin, central China using chemical and multi-isotope data. The results suggest that lithium enrichment in these brines is the result of interaction with clastic host rocks and dilution by meteoric water.

Summary: Due to the lack of deep wells in the broader region, studying mud volcanic deposits can improve the geological understanding of the Mediterranean Ridge. In this study, biostratigraphic and geochemical analyses were performed on mud breccia deposits from five Mud Volcanoes in the central MR. The results indicate the origin of these deposits and provide insights into the source rock potential. Seismic data is also used to determine the distribution of major lithostratigraphic formations.
