Volcanic ash drives contrasting redox shifts and biogeochemical feedbacks in ancient marine and lacustrine systems

Communications Earth & Environment
Volcanic eruptions are major perturbations to Earth’s biogeochemical cycles, yet their long-term effects on nutrient dynamics and ecosystem recovery remain unclear.

Volcanology of the Raventhorpe and Pokeno West Volcanic Complexes, South Auckland Volcanic Field

, 2012
The South Auckland volcanic field hosts at least 82 volcanic centres throughout the Pukekohe, Bombay, Tuakau, Pukekawa and Onewhero regions. The monogenetic basaltic volcanic field was active between 1.59 to 0.51 Ma, producing tuff rings, maar craters ...

Volcanic and sedimentary processes in phreatomagmatic volcanoes [PDF]

, 1982
Phreatomagmatic volcanoes form when ascending magma explosively interacts with surface or groundwater at shallow depths. Three types of phreatomagmatic activity are recognised- phreaticp phreatomagmatic (s. s. ) and surtseyan - based on the degree of

Towards an understanding of thermodynamic and kinetic controls on the formation of clay minerals from volcanic glass under various environmental conditions

, 1996
lmogolite is the kinetically and thermodynamically favoured weathering product from rhyolitic volcanic glass in the soil-forming environment. However, on thermodynamic grounds imogolite would also appear to be the favoured alteration product of rhyolitic

Single‐Nucleus Multiomic Analysis Reveals Immune–Metabolic Reprogramming Consistent With Maladaptive Trained Immunity in HIV‐Associated Neurocognitive Disorders

Glia, Volume 74, Issue 8, August 2026.
Single‐nucleus multiomic profiling of postmortem brain reveals coordinated immune, metabolic, and epigenomic reprogramming in glia of people with HIV consistent with maladaptive trained immunity sustaining neuroinflammation in HAND. ABSTRACT HIV‐associated neurocognitive disorders (HAND) remain prevalent in people with HIV (PWH) despite effective ...

Geology and Chronology of the Lunar Taruntius Crater: Implications for the Retention Age of Lunar Ray Patterns and Lifetime of Lunar Explosive Volcanism

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Taruntius crater, situated between Maria Fecunditatis, Crisium, and Tranquillitatis, is characterized by a prominent bright ray system and a floor‐fractured morphology and has long been interpreted as a relatively young Eratosthenian or Copernican crater.
