Detrital zircon SHRIMP U-Pb age study of the Cordillera Darwin Metamorphic Complex of Tierra del Fuego : sedimentary sources and implications for the evolution of the Pacific margin of Gondwana [PDF]

, 2010
The Cordillera Darwin Metamorphic Complex in the southernmost Andes includes a basement of probable Palaeozoic age, a mid-Jurassic and younger volcano-sedimentary cover, and a suite of Jurassic granites, all of which were jointly metamorphosed during the

Structure of the North‐Central Chile Subduction Zone From Local Earthquake Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The fluid cycle in subduction zones prescribes large parts of its structure and seismogenic behavior. Background seismicity inside the downgoing slab is linked to fluid release from dehydration reactions, whereas fluid overpressure along the plate interface can alter interplate coupling, megathrust earthquakes, and the presence or absence of ...

Heavy Metals in Soils: An Investigation of the Contaminated Floodplains Around the Sinu River, Colombia

GeoHealth, Volume 10, Issue 3, March 2026.
Abstract Heavy metal contamination in rivers mostly originates from anthropogenic sources such as industrial activities, mining, agriculture, and urban runoff. These metals accumulate in river sediments and impact living organisms and the surrounding ecosystem. Historically, some rivers in Colombia have faced issues related to heavy metal contamination,

Conservation evidence is biased but can support decision‐making for prevalent and severe threats in tetrapods

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Despite taxonomic and spatial biases, substantial conservation evidence is available to support decision‐making by practitioners, particularly for the most prevalent and severe threats. Given the current biodiversity crisis, it is critical that this information is more widely used and that coordination among academic and practitioner partners is ...
