Statistical separation of observed global and European climate data into natural and anthropogenic signals [PDF]

open access: yes, 2003
Observed global and European spatiotemporal related fields of surface air temperature, mean-sea-level pressure and precipitation are analyzed statistically with respect to their response to external forcing factors such as anthropogenic greenhouse gases,

Rhyolite generation prior to a Yellowstone supereruption: insights from the Island Park-Mount Jackson rhyolite series [PDF]

open access: yes, 2017
The Yellowstone volcanic field is one of the largest and best-studied centres of rhyolitic volcanism on Earth, yet it still contains little-studied periods of activity.

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 915-924, April 2026.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Crustal Magma Storage and Plumbing System Beneath the Tianchi and Wangtian'e Volcanoes, Changbaishan Intraplate Volcanic Field, China and North Korea

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The Changbaishan volcanic field, which includes the Tianchi and Wangtian'e volcanoes in China and the Namphothe volcano in North Korea, is one of the most complex and hazardous volcanic regions on Earth due to its tectonic setting and explosive Holocene activity.

Jungian categories as modes of reading: The case of Graham Greene's The Heart of the Matter and Aldous Huxley's Time Must Have a Stop

open access: yesOrbis Litterarum, Volume 81, Issue 2, Page 89-110, April 2026.
Abstract This essay advocates renewed attention toward Jungian literary criticism, emphasizing its unique and creative perspectives on both fictional worlds and on reading. A fresh turn to Jungian criticism offers, in particular, valuable insight for texts on the peripheries of the canon.

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone

open access: yesTerra Nova, Volume 38, Issue 2, Page 106-115, April 2026.
ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

Explosive volcanism, shock metamorphism and the K-T boundary [PDF]

open access: yes
The issue of whether shocked quartz can be produced by explosive volcanic events is important in understanding the origin of the K-T boundary constituents.

Teleseismic Radial Anisotropy Reveals a Sill‐Dominated Magma Reservoir Beneath the Valles Caldera, New Mexico

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Valles Caldera (VC), one of the largest Quaternary silicic calderas in North America, formed by explosive rhyolitic eruptions. Seismic studies suggest a crustal magmatic reservoir beneath the caldera with low‐velocity anomalies, but resolving the detailed geometry of localized melt requires constraints from seismic anisotropy.
