Search for impact ejecta at the Paleocene–Eocene boundary

Meteoritics &Planetary Science, EarlyView.
Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

Sedimentology, EarlyView.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Dispersion and Intersection of Hydrothermal Plumes in the Manus Back-Arc Basin, Western Pacific

Geofluids, 2020
The composition of hydrothermal plumes reflects the physical and chemical characteristics of seafloor hydrothermal fluids, which in turn reflects the host rock and subseafloor reaction conditions as well as the water column processes that act to alter ...

Hydrogen uptake activities of metagenomic fosmid clones derived from hydrothermal vent systems along the Mid-Atlantic Ridge during METEOR cruise M78/2

, 2021
Metagenomic fosmid libraries were constructed from hydrothermal chimneys and fluids and screened for hydrogen uptake (hydrogenase) activity by means of an activity-based screen. The hydrogen uptake activity of positively screened clones was determined by

The Control of End‐Member Iron‐to‐Sulfide Ratios on Hydrothermal Plume Geochemistry at the Rainbow, Broken Spur, and Lost City Vent Fields in the Mid‐Atlantic Ridge

Geochemistry, Geophysics, Geosystems
The Mid‐Atlantic Ridge (MAR) represents a unique tectonic environment hosting distinct hydrothermal vent fields. Considering the growing interest in understanding the role of hydrothermal vents in both local and global ocean systems, the MAR offers an ...

Voltammetric Investigation Of Hydrothermal Iron Speciation

Frontiers in Marine Science, 2016
Hydrothermal vent fluids are highly enriched in iron (Fe) compared to ambient seawater, and organic ligands may play a role in facilitating the transport of some hydrothermal Fe into the open ocean.

The chemistry of iron in hydrothermal plumes

, 2008
This thesis investigates the role of submarine hydrothermal vents in the global marine Febudget. While debate continues over the sources of dissolved Fe to the global deep-oceandissolved Fe budget, it had been presumed, until recently, that all the Fe ...

Astronomical and atmospheric impacts on deep-sea hydrothermal vent invertebrates

, 2017
Ocean tides and winter surface storms are among the main factors driving the dynamics and spatial structure of marine coastal species, but the understanding of their impact on deep-sea and hydrothermal vent communities is still limited. Multidisciplinary
