SiO$_2$-mediated facile hydrothermal synthesis of spiroffite-type Co$_2$Te$_3$O$_8$ [PDF]

open access: yesarXiv
The hydrothermal synthesis of novel materials typically relies on both knowledge of the redox activities of all cations present in the reaction solution and a small toolset of so-called mineralizers to tune the solution's overall chemical potential.

Sustainable seabed mining: guidelines and a new concept for Atlantis II Deep

open access: yes, 2012
The feasibility of exploiting seabed resources is subject to the engineering solutions, and economic prospects. Due to rising metal prices, predicted mineral scarcities and unequal allocations of resources in the world, vast research programmes on the ...

Accessory minerals: a provenancing tool for steatite quarries

open access: yesArchaeometry, EarlyView.
Abstract Steatite has been a widely traded material across a range of archaeological contexts. Yet, challenges inherent to determining its provenance limits our understanding of the networks and mechanisms of its exchange. We present a robust new accessory mineral provenancing “fingerprint” method based their specific growth history.

The interplay of faulting, magmatism and Hydrothermal fluid flow at oceanic ridges - new insights from numerical modeling [PDF]

open access: yes, 2015
The dissertation examines the interplay between the convection of hydrothermal fluids, magmatic processes and permeable faults in the oceanic lithosphere in Mid-Ocean Ridge settings.

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine 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.

Exploring the origins of magnetization within the Chicxulub crater upper peak ring

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 4, Page 823-848, April 2025.
Abstract Large terrestrial impacts may produce vast subsurface hydrothermal systems, capable of generating conditions favorable to the origin of life. Modeling suggests that these systems may persist for >1 million years for basin‐sized craters; however, direct experimental constraints on hydrothermal system duration are needed.

Molecular Insights into Yb(III) Speciation in Sulfate-Bearing Hydrothermal Fluids from X-ray Absorption Spectra Informed by ab initio Molecular Dynamics [PDF]

open access: yesarXiv
Rare earth elements (REEs) are critical for advanced technologies, yet in hydrothermal aqueous solutions the molecular level details of their interaction with ligands that control their geochemical transport and deposition remain poorly understood. This study elucidates the coordination behavior of Yb(III) in sulfate-rich hydrothermal fluids using in ...
