Detrital zircon and apatite (U‐Th)/He geochronology of intercalated baked sediments: a new approach to dating young basalt flows [PDF]

, 2011
Simple numerical models suggest that many basaltic lava flows should sufficiently heat the sediments beneath them to reset (U‐Th)/He systematics in detrital zircon and apatite.

A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Could large‐scale silicon supplementation of crop‐lands mitigate the impacts of climate change?

PLANTS, PEOPLE, PLANET, EarlyView.
Intervention strategies that involve supplementing crop‐lands with silicon have significant scope for carbon capture and drought mitigation, offering wide‐ranging societal impacts. These include contributing to decarbonisation goals, enhancing food security, providing economic benefits and reducing environmental damage associated with intensive ...

Rift and plume: a discussion on active and passive rifting mechanisms in the Afro-Arabian rift based on synthesis of geophysical data [PDF]

Solid Earth
The causal relationship between the activity of mantle plumes and continental break-up is still elusive. The Afro-Arabian rift system offers an opportunity to examine these relationships, in which an ongoing continental break-up intersects a large ...

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

On the potential for CO₂ mineral storage in continental flood basalts – PHREEQC batch- and 1D diffusion–reaction simulations

Geochemical Transactions, 2012
Continental flood basalts (CFB) are considered as potential CO2 storage sites because of their high reactivity and abundant divalent metal ions that can potentially trap carbon for geological timescales.

Extracting the geochemical characteristics of magmas in different global tectono-magmatic settings using sparse modeling

Frontiers in Earth Science, 2022
In this study, key geochemical features of magmas formed in eight different tectono-magmatic settings (mid-ocean ridges, oceanic islands, oceanic plateaus, continental flood basalt provinces, intra-oceanic arcs, continental arcs, island arcs, and back ...
