Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Neogene Hydrothermal Fe‐ and Mn‐Oxide Mineralization of Paleozoic Continental Rocks, Amerasia Basin, Arctic Ocean

Geochemistry, Geophysics, Geosystems
Rocks dredged from water depths of 1,605, 2,500, 3,300, and 3,400 m in the Arctic Ocean included Paleozoic continental rocks pervasively mineralized during the Neogene by hydrothermal Fe and Mn oxides.

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Ocean circulation contributes to genetic connectivity of limpet populations at deep‐sea hydrothermal vents in a back‐arc basin

Evolutionary Applications
For endemic benthos inhabiting hydrothermal vent fields, larval recruitment is critical for population maintenance and colonization via migration among separated sites. The vent‐endemic limpet, Lepetodrilus nux, is abundant at deep‐sea hydrothermal vents

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

The effect of early diagenetic processes on the quantification of fossil micrometeorite abundance and flux in the geological record

Meteoritics &Planetary Science, EarlyView.
Abstract Fossil micrometeorites (MMs) recovered from lithified sedimentary rocks, particularly iron‐rich (I‐type) cosmic spherules (CSs) provide valuable insights into past dust‐forming events. Their abundances, when combined with estimates of local sedimentation rates can be used to reconstruct the flux of extraterrestrial dust.

Dating C/S Structures in Syntectonic Granites by In Situ Rb‐Sr Analyses on Muscovite

Terra Nova, EarlyView.
ABSTRACT The interplay of crystallisation, deformation and fluid–rock interactions makes deciphering geochronological information complex in syntectonic granites. In this study, we apply in situ Rb‐Sr analyses to selected samples from the Questembert Variscan syntectonic granite in Western France, which was emplaced along the South Armorican Shear Zone
