Summary: This study uses a multi-proxy approach to characterize environmental changes and late Pleistocene to Holocene sequence stratigraphic architecture in 16 cores from the northern Sunda Shelf off the east coast of Peninsular Malaysia. Five chronostratigraphic units are recognized, revealing the geologic response of the shelf to sea-level rise and the sequence stratigraphic development of tropical, shallow shelf depositional sequences.

Summary: Incised valley fills are complex, corresponding to multiple sea-level cycles and making stratigraphic interpretation challenging. A study of the Holocene succession in Ravenglass Estuary revealed five main stages of formation, from river incision to final backfilling and merging of rivers. The best-connected reservoir-equivalent sands in this tide-dominated setting are found in stable channels.

Summary: Integrated sedimentological and petrographical analyses were used to reconstruct the paleoenvironment of the Mishan Formation (late Burdigalian-Serravallian) in the Dezful Embayment of the Zagros foreland basin. The results suggest the presence of a tide-dominated mixed siliciclastic-carbonate homoclinal ramp with the development of organic buildups in a tropical to subtropical warm water environment. These findings provide important insights into the Middle Miocene climate transition and the geological history of the Dezful Embayment.

Summary: This study used high-resolution seismic stratigraphy to investigate the key surfaces and sedimentary filling pattern of the Coreau incised valley system in NE Brazil. Six key surfaces and five seismic units were identified, showing features such as the sequence boundary and sedimentary stacking pattern. The research revealed the influence of antecedent topography and strong control in incision and sedimentation.

Summary: The warmer climate during the Miocene Climate Optimum (approximately 16.9-14.7 Ma) may serve as a reference for future pessimistic warming scenarios. The FGOALS-g3 climate model simulates the temperature changes during this period well, with small biases compared to proxy data. Changes in surface albedo and greenhouse effect contribute to the warming effect during the Miocene.

Summary: This study examines the late Miocene basal carbonate member of the Bouse Formation along the lower Colorado River, presenting new evidence to support a tidal origin for the southern Bouse Formation and post-Miocene uplift of the lower Colorado River Valley and adjacent areas. The research explores the applicability of tidal strait models in a continental oblique-rift setting and highlights the importance of analyzing sedimentary facies, cross-bedding architecture, and palaeocurrent data in understanding depositional processes and environments in tidal straits.

Summary: The Changjiang River discharges a large amount of sediment into the East China Sea, influencing the evolution of the downstream Qiantang River system. This study quantitatively tracks the change in sediment import from the Changjiang to the Qiantang River valley over the past 8,000 years. As the Changjiang delta prograded, the proportion of sediment input from the Changjiang to the Qiantang River valley decreased.

Summary: This study documents the Late Quaternary incised valleys and their characteristics in the Balingian-Central Luconia shelf using extensive three-dimensional seismic data, high-resolution seismic data, and boreholes. The main Tatau incised valley and its tributary Suai incised valley fed the Tatau-Suai shelf-edge delta. This study emphasizes the importance of documenting incised valley systems in a broader source-to-sink framework for understanding ancient incised valleys in comparable geological settings.

Summary: The study conducted ichnological analysis on upper Miocene sediments to reveal variability in ichnofacies attributes and distribution at the Rifian Corridor. It found that hydrodynamic energy is the major factor controlling trace maker communities, leading to differences in ichnofacies associated with turbidites, contourite, and shallow marine sediments.

Summary: This study investigates and compares the textures of tufa in Mono Lake and Searles Valley. It finds that a t-Distributed Stochastic Neighbor Embedding (t-SNE) algorithm can be used to quantitatively compare the visual similarity of textures. The study provides a robust assessment of the feasibility of using Mono Lake as a modern analogue for Searles Valley and makes significant progress towards using texture as a metric for the environment in which tufa formed.

Summary: Aeolianites with a mixed clastic and carbonate detrital mineralogy are typical deposits of tropical coastal desert environments. The study of the Ghayathi Formation in the United Arab Emirates provides a comprehensive dataset that reveals the complex depositional and diagenetic evolution of a mixed siliciclastic-carbonate aeolianite.

Summary: The Zhuhai Formation in the Pearl River Mouth Basin contains extensive shelf-edge delta and slope fan deposits in the northern South China Sea. The study systematically documents the depositional architecture and delivery mechanism of sandy deposits from the shelf margin to the lower slope through integrated analysis of well-log, seismic, and core data. Four major depositional facies are identified: shelf-edge incised channels and deltas, amalgamated slump-channel complexes, slope gullies, and slope fan deposits. The channelization and large-scale slumping along the shelf-edge delta front are regarded as the most important dispersal mechanisms delivering sandy sediments across the shelf margin.

Summary: This study highlights the limitations of using carbonate archives in reconstructing past elevations in the Central Andes. The results show that paleoaltimetry estimates based on carbonates significantly underestimate the results obtained from volcanic glass using stable hydrogen isotopes.

Summary: The Marnes Bleues Formation in the Vocontian Basin of Southeastern France contains dark-colored levels that are typically rich in organic matter. However, a multi-parameter study revealed that these levels vary in their organic matter content, sedimentation and accumulation rates, and other characteristics. Despite the variations, all the dark levels were found to have low to modest enrichments in organic matter. This suggests that factors such as productivity and oxygen levels alone are not sufficient to induce high accumulations of organic matter. These findings may have broader implications for other settings, regardless of their geological age or location.
