Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Origin of the King's Trough Complex (North Atlantic): Interplay Between a Transient Plate Boundary and the Early Azores Mantle Plume

Geochemistry, Geophysics, Geosystems
The King's Trough cuts into an area of thickened oceanic crust associated with the 45°N melting anomaly at the Mid‐Atlantic Ridge. Here we present a comprehensive geochemical data set and new 40Ar/39Ar age and bathymetric data from magmatic rocks from ...

Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, EarlyView.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.

A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

Water and Environment Journal, EarlyView.
ABSTRACT The presence of microplastics (MPs) in groundwater has emerged as a significant concern due to their environmental impact and the threat they pose to vital water resources, groundwater being one of the most important freshwater sources in the world.
