Limnology and Oceanography, Volume 71, Issue 5, May 2026.Abstract Enrichment patterns of the redox‐ and bio‐sensitive trace elements U, V, Cr, and Ni in margin sediments are essential for environmental reconstructions. However, their sedimentary accumulation pathways are not fully understood. While the accumulation of toxic trace elements like Cd, Hg, Pb, and Zn has been relatively well studied in fish ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Microspherules formed by lightning strikes
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 743-767, May 2026.Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Contact Metamorphism in Southern California [PDF]
, 1954 A highly condensed introduction to "Contact metamorphism in southern California" is obviously not the place in which to indulge in semantic niceties nor to engage in terminological tussles, and thus the title is not intended to reflect a carefully ...

Mountain‐top spherules: Criteria to identify natural and synthetic particles
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 898-913, May 2026.Abstract Natural microspherules are important tracers of geologic and environmental processes in modern and ancient deposits. However, anthropogenic contamination can dilute natural collections by releasing synthetic microspherules into the environment.

The Effect of Organic and Inorganic Modifiers on the Physical Properties of Granite Residual Soil
Advances in Materials Science and Engineering, 2022 As a kind of highly weathered special soil in South China, granite residual soils (GRS) feature high strength and high void ratio in a dry environment, so they tend to disintegrate in water and cause geological disasters including collapse.

The effect of F on the density of haplogranite melt [PDF]
, 1993 The densities and thermal expansivities of F-bearing haplogranitic glasses and liquids have been investigated using a combination of scanning calorimetry and dilatometry. F2O-1 reduces the density of haplogranitic liquids (at 750 °C) from 2.295 + 0.006 g/
