Summary: The analysis of sedimentary facies of the Mesoproterozoic Srisailam Formation in India reveals a variety of depositional environments, including lacustrine, deltaic, and aeolian facies. The evolution of the Srisailam rift-basin may have been influenced by lithospheric doming and magmatic activity, with sedimentation style resembling the Newark-type lacustrine facies complex. The deposition in the Srisailam sub-basin can be compared to the Cenozoic rift system of Europe, suggesting simultaneous rift development with orogenic activity.

Summary: Coal facies research helps determine the genetic type and formation environment of coal, while rare earth elements are used to analyze the source and depositional environment characteristics of coal. By analyzing the maceral composition and REE content of coal samples from different periods, and combining traditional REE indicators with coal facies parameters, it is possible to assess the characteristics of coal seams in terms of depositional environment, oxidation-reduction conditions, coal-forming plants, hydrodynamic conditions, and provenance.

Summary: The 31-meter thick section in the Middle Ombrone Basin of Tuscany, which includes the fossil find of an Early Pliocene baleen whale (Brunella), was analyzed using paleomagnetic, micropaleontological, and sedimentary facies analyses. The deposits indicate a deepening upward inner shelf environment and were deposited during the interval of polarity Chron C3n.2n, estimating the depositional age of Brunella to be approximately 4.6 million years ago. The sedimentary facies and benthic Foraminifera association suggest deposition above fair-weather base level.

Summary: The objective of this study is to analyze the facies, depositional environment and reservoir quality of the Early Cambrian Xiaoerbulake Formation in the Tarim Basin. The study shows that the deposits of the Xiaoerbulake Formation occurred in a ramp setting, with seven facies associations and ten facies types. High-quality reservoirs were found in the high-energy shoal environments, characterized by different pore space types. This research contributes to our understanding of the stratigraphic framework, sedimentary-facies evolution, and high-quality reservoir distribution, aiding in hydrocarbon exploration and production.

Summary: This study investigates sediment gravity flows in the Aberystwyth Grits Group and finds that sole marks are suitable for reconstructing depositional processes and environments in deep-marine sedimentary successions. The researchers subdivide an outcrop into seven lithological units and propose a new process model for hybrid event beds. The study demonstrates the importance of sole marks in sedimentological studies beyond their traditional use as indicators of paleoflow direction.

Summary: This study utilized outcrop gamma-ray logs, outcrop observations, and total organic carbon analysis to establish the stratigraphic framework of organic-rich rocks in the Huai Hin Lat Formation. It identified five sedimentary facies, two facies associations, and a lacustrine basin-fill depositional environment subdivided into deep lacustrine and sublacustrine fans associated with turbidity currents. The study highlighted the close relationship between total gamma-log characteristics, lithologies controlled by clay mineral compositions, and the usefulness of U concentrations in identifying organic-rich rocks.

Summary: This study investigates the depositional environment of Talcher coal, the largest coal reserve in India, through analyses of its chemical composition, physical properties, petrography, and stable carbon and nitrogen isotopic composition. The results indicate that the coal was formed in a palaeomire with changing lake water conditions, and was dominated by forest vegetation.

Summary: This study aims to present a detailed facies analysis and depositional environment of the Carboniferous age, Singa Formation at Pulau Ular, Langkawi, Kedah. Through the examination of one exposed outcrop and the creation of a sedimentary log, the study identified eight facies and concluded that the area had a coastal and glacier depositional environment. The study is crucial in reconstructing the past glacial pattern and understanding the link between glacial processes, history, and the Earth system.

Summary: This study presents a quantitative analysis of the variability in facies architectures of Gilbert-type deltas, revealing high variability in the geometry and facies of these deltas. Different διμensions of the deltas result from relationships between accommodation, sediment supply, and delta lifespan. Changes in allogenic and autogenic mechanisms are inferred as causes for significant differences in facies organization, highlighting the marked variety of architectural and sedimentological properties of Gilbert-type deltas. This information is valuable for the recognition and correlation of deltaic bodies in the subsurface.

Summary: Langkawi is located in the North-western Domain of Western Belt of Peninsular Malaysia and is composed of Palaeozoic sedimentary rocks. The study emphasizes the importance of sedimentology, stratigraphy, and depositional environment analysis in advancing our understanding of Earth's complex behaviors. The research on the Machinchang Formation in Langkawi revealed nine facies types representing clastic sediment deposition in a shallow marine environment during a relatively short regression period.

Summary: Titanium has long been considered immobile during weathering and diagenetic processes, but our study shows that authigenic titania can be formed through weathering of Ti-bearing silicates in a variety of facies. The morphology of authigenic titania nanoparticles varies predictably across different depositional environments, suggesting it could be a sensitive proxy for sedimentary environment and porewater chemistry. This finding has implications for depositional facies analysis.

Summary: This study examined the depositional environments and petroleum source rock potential of Middle Jurassic and Lower Cretaceous lacustrine sedimentary rocks in central Mongolia. The Middle Jurassic shale was found to have a mixed oil and gas potential source rock, while the Lower Cretaceous shales showed a high oil-prone but thermally immature character. The organic geochemical characteristics and depositional environments of these rocks are similar to source rocks in western Chinese basins and eastern Mongolian basins, respectively.

Summary: This study compares the effects of two types of cobalt-based nanoparticles on lung cells and finds that cobalt nanoparticles are more toxic to cells than cobalt-iron oxide nanoparticles, possibly due to the higher release of Co2+ ions by cobalt nanoparticles. Additionally, the study suggests that CalceinAM alone is insufficient to assess the toxicity of cobalt-based nanoparticles, and other methods should be used for further confirmation.

Summary: A body weight prediction model was developed using milk production traits, providing a useful indicator for energy balance evaluation in dairy cows. The deep neural network (DNN) model showed the best predictive accuracy for body weight compared to other models. It was found that the transition from negative to positive energy balance varied among cows. Energy balance indexes were proposed to estimate and monitor individual cows' energy balance during lactation.

Summary: This study investigates the steady flow of viscoelastic fluid in a deformable channel. The mathematical structure for computing the impacts of fluid viscoelasticity on the flow is provided, and the dimensionless variables influencing the interaction between the fluid and structure are identified. The results show that the converging and diverging sections of the channel are affected similarly by the inertial forces and channel opening. Longer strain delaying time and shorter stress relaxation phase improve the velocity profile of the fluid flow.
