Sediment Characteristics and Architecture of Triangular‐Shaped Murtoos: A Test of Murtoo Formation Hypotheses

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Murtoos and murtooized terrains are new types of subglacial landforms found in the Fennoscandian Ice Sheet (FIS) and Cordilleran Ice Sheet (CIS) regions. LiDAR‐based morphometric analyses have revealed substantial morphometric diversity among murtoos and murtoo‐related landforms, while sedimentological excavations have documented a wide range of ...

Zircon U-Pb age, trace element and Hf isotope composition of Sepon Au-Cu deposit, Laos: tectonic and metallogenic implications

China Geology, 2018
: The Truong Son Fold Belt, located at the northeastern margin of the Indochina Block, is considered to be tectonically linked to the subduction of the Paleotethys Ocean and subsequent collision. Sepon is one of the most important super large deposits of

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, Volume 61, Issue 9, Page 2940-2957, September 2026.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Correlation between ore mineralogical composition at different depths and Bond Work Index for the Erdenetiin Ovoo Cu-Mo porphyry deposit, Mongolia

Mongolian Geoscientist
The Erdenetiin Ovoo Cu-Mo porphyry deposit in Mongolia is the largest copper mine corporation in the nation. In this study, we investigate the grinding properties of biotite granodiorite and granodiorite rock alteration relative to variations in mine ...

Zooplankton reliance on autochthonous and allochthonous resources across mountain lakes revealed through essential amino acid δ13C analysis

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Terrestrial subsidies shape aquatic ecosystem structure and function, serving as important energy channels for consumers when phytoplankton and other autochthonous resources are limited. Despite this, quantifying the assimilation of allochthonous nutrients by aquatic consumers can be challenging. Here, we show terrestrial plants, benthic algae,

Variation of Sr and Pb isotopes in megacrystic K-feldspar from the Cathedral Peak Granodiorite, California [PDF]

, 2016
In-situ micro-drilling of K-feldspar megacrysts from the Late Cretaceous Cathedral Peak Granodiorite of the Tuolumne Intrusive Suite, California, provided material to study Sr and Pb isotopic compositions and trace element variation recorded by these ...

Petrogenesis and Tectonic Implication of the Newly Identified Rhyacian and Orosirian Orthogneisses in the Northwestern Part of the Gyeonggi Massif (Soyeonpyeongdo and Ganghwado Areas), South Korea: Constrained From Whole‐Rock Geochemistry and Zircon U‐Pb‐Hf Isotopic Compositions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The Gyeonggi Massif is one of the major Precambrian basements in the Korean Peninsula where Paleoproterozoic orthogneiss and paragneiss were widely exposed. In this study, newly identified Rhyacian to Orosirian meta‐igneous rocks from the northwestern Gyeonggi Massif (Soyeonpyeongdo and Ganghwado areas) were investigated to elucidate their ...

Contrasting Effects of Phosphate on Arsenic Mobility and Human Exposure in Agricultural Soils

GeoHealth, Volume 10, Issue 9, September 2026.
Abstract Arsenic in agricultural soils may pose human health risks due to elevated concentrations and increased soil ingestion associated with dust generation. However, the actual exposure depends on the fraction of As that becomes bioaccessible under gastrointestinal conditions. This study evaluates As mobility, bioaccessibility, and associated health

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...
