Summary: This study focuses on the relationship between crustal necking and mineral deposit formation. Observations from the Mont-Blanc fossil detachment system show a direct link between fluid and reaction-assisted breakdown of silicates, metal transfer and trapping along detachment faults, and the overlying sedimentary rocks during necking. These findings suggest that necking and Pb-Zn deposit formation may be closely linked.

Summary: Researchers have discovered a new species of elcanid insects in the lower Albian Jinju Formation, and used Wavelength Dispersive Spectrometer analysis for the first time on insect fossils. They found that elcanid insects may have used leaf-shaped spurs on their hind legs to jump on the water surface as an effective way to escape from predators.

Summary: The study found that contact-line motion has a significant impact on the deposit morphology of solution-based inks, with a fixed contact line producing exclusively ring-like deposits and a mobile contact line leading to different deposit morphologies. By adjusting ink solvent composition and substrate wetting behavior, uniform and flat deposits can be achieved through inkjet printing.

Summary: The aim of the research is to study the complex reservoir rocks in the Lower Berezovskaya subformation in the north of Western Siberia. The study reveals that the clay-siliceous deposits in this subformation are made up of various types of silicites, presenting unique petrophysical and mineralogical characteristics that pose difficulties in the development of productive layers. Through comprehensive laboratory studies, it is found that the silicites are caused by a complex void space structure consisting of different genetic types of voids ranging in size from micron to submicron dimensions.

Summary: The Cretaceous sedimentary succession in the Chotts basin of southern Tunisia is characterized by facies and thickness variations controlled by N-S and E-W trending fault networks. These faults, particularly the N-S faults, played a significant role in the extensional phase during the Aptian-Albian period, contributing to the structural division of the basin and the formation of the Atlas belt to the north and Saharan platform to the south. The interference between N-S and E-W faults directions, along with halokinesis movement, led to the emergence of specific paleohigh structures during this extensional phase, causing sedimentary hiatus in parts of the Chotts basin and Tunisian Atlas.

Summary: The Dongji and Maluntou gold deposits are the two largest ones in the Dongkeng Volcanic Basin, SE China, formed during the Turonia-Albian period, and are classified as intermediate-sulfidation epithermal deposits hosted by volcanic rocks. The deposits were characterized by multiple stages of mineralization and the occurrence of visible and invisible gold within different generations of pyrite.

Summary: This study provides biomarker evidence for wildfires and paleoclimate changes during the Late Cretaceous in the Songliao Basin, NE China. The presence of various aromatic hydrocarbons in lacustrine deposits indicates changes in oxygen availability, humidity, and fire activity.

Summary: This study revisits the Crustacea preserved in Cretaceous plattenkalk deposits from Mexico, revealing new findings including isopods, palinurid lobsters, and crabs. Descriptions of previously reported species are extended based on new material available. These findings provide insights into the morphology and ecology of these fossilized animals.

Summary: Sheltered preservation is a known phenomenon where organisms are trapped within cephalopod shells, providing important paleontological data. This study reports the discovery of the first crinoid preserved inside an early Albian ammonite in Madagascar. The crinoid belongs to the phyllocrinid family and represents the first finding of this family from Africa and the second from the southern margin of the Tethys. This finding highlights the potential use of ammonite shells for studying echinoderms.

Summary: This study reconstructs prehistoric copper mining activities in Styria, Austria, using a multi-proxy approach on calcareous lake sediments. The results indicate regional mining during the mid-Bronze Age, Hallstatt period, and late La Tene period, with strong correlations of trace elements associated with local copper ores.δ15N and δ34S were not effective in identifying past mining activity but helpful in inferring erosional changes in the lake catchment.

Summary: The study investigates the relationship between jellyfish blooms and the dynamics of anchovy and sardine populations in the Western Mediterranean Sea. The results show that jellyfish blooms have a negative impact on the abundance, biomass, and fitness of these fish species, in addition to changes in environmental conditions. This suggests that jellyfish blooms should be considered as a likely cause of change when analyzing small pelagic fish populations.

Summary: Microzooplankton plays an important role in transferring microbial food web carbon to small pelagic fishes along the southwest coast of India, including Indian oil sardine, Indian mackerel, and Commerson's anchovy. The diet composition varied among the three fish species, with oil sardine mainly feeding on diatoms, Indian mackerel consuming phytoplankton, microzooplankton and copepods, and Commerson's anchovy primarily relying on a carnivorous diet including copepods, fish eggs, ostracods, lucifers, and microzooplankton. The study concludes that microzooplankton provides nutritional support to small pelagic fishes in the region, but the extent varies depending on the fish species and seasons.
