Summary: This study focuses on the sedimentological facies and provenance characteristics of the Neogene West Baram delta successions in the Baram Delta province. The results reveal that the sediments are derived from multirecycled sources, including the Paleogene Rajang Group turbidites and the Oligocene to Lower Miocene Nyalau-Tatau delta deposits.

Summary: Dating the tectonic melange in West Sarawak, Borneo using K-Ar analysis of illite provides constraints on the deformation age and duration of subduction activity. The results suggest that subduction in Sarawak may have continued until approximately 60 Ma, with major uplift events occurring at around 36 Ma. This study also highlights the potential of using tectonic melange to extract information about unknown periods of metamorphic melt generation during subduction.

Summary: The coastal region of the South China Sea is crucial for studying the thermo-tectonic histories of onshore and offshore areas, and the surface response to deep-seated mantle anomalies. This study analyzes low temperature thermochronological data from onshore granite samples to understand the thermo-tectonic evolution of the southern margin of the South China Block. The findings reveal a three-stage cooling pattern, with an early Cretaceous to early Late Cretaceous cooling phase, followed by thermal quiescence, and then a further cooling episode starting in the early Eocene. The study also suggests that the tectonic evolution of the region was controlled by subduction and plate convergence during different geological periods.

Summary: The study of the Hainan Delta core reveals four stages of delta development supported by factors such as grain size, dinoflagellate cysts, and diatoms. The organic matter is a mixture of terrigenous and marine sources, with rapid mineralization leading to high abundance of dinoflagellate cysts. The rarity of fossil diatoms can be attributed to high dilution and lateral transport processes.

Summary: High-quality ocean colour observations are increasingly accessible and can be used to support water quality measurements. This paper presents a newly developed model for studying the dynamics of total suspended solids (TSS) along the southwest coast of Sarawak, Borneo using MODIS Aqua satellite data. The results show that TSS levels in this region are within local standards, but with significant variability, especially during monsoon periods.

Summary: This study uses thermomechanical simulations to validate the correlation between the opening of the South China Sea and the age of the Proto South China Sea (PSCS), suggesting that the PSCS oceanic plate formed at least 65 million years ago. This has significant implications for reconstructing ancient plate tectonics.

Summary: The Paleogene sedimentary successions of the Tarim Basin in western China are reconstructed to understand the palaeogeographic evolution and palaeoenvironmental changes. The study reveals the major regression of the proto-Paratethys Sea, the transition from marine to continental-lacustrine sedimentation, and the role of tectonic and eustatic forces in controlling the late Paleogene transgression regression. The findings provide insights into the sedimentary response to Paleogene sea-level change and tectonic events in Central Asia.

Summary: The South China Sea is a major hotspot for plastic discharge and accumulation of microplastics. Microplastic abundance is higher in coastal areas compared to basin areas, while sediment abundance shows less variation. Basin-scale circulation and regional currents play an important role in the transport of microplastics.

Summary: The study explores the evolution of isolated carbonate buildups in the Middle Miocene in Central Luconia in the southern South China Sea. It shows the different stages of development of the buildups and how they are influenced by tectonics, eustatic fluctuations, and other factors. The research highlights the complex interactions between endogenic and exogenic processes that shape the reefal evolution and architecture of the buildups.

Summary: Identifying distinct tectonic units is crucial for understanding the geotectonic framework and distribution of oil and gas resources in the South China Sea and its adjacent areas. This study divides the region into several distinguishable tectonic units based on known boundary markers, providing valuable insights into the tectonic activities, crustal structural properties, and evolutionary records of each unit.

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.
