Twenty‐Three Years of Landslide Activity in the European Alps–Part 2: Investigating Triggers and the Impacts of Meteorological Change on Landslide Occurrences

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides represent one of the most devastating natural hazards in mountainous regions, posing significant threats to human safety, infrastructure and ecosystems. It is well established that there is a connection between meteorological factors and landslide occurrences but the mechanisms of these interactions and the impacts of climatic ...

Elastic and Frictional Properties of Fault Zones in Reservoir-Scale Hydro-Mechanical Models—A Sensitivity Study

Energies, 2020
The proper representation of faults in coupled hydro-mechanical reservoir models is challenged, among others, by the difference between the small-scale heterogeneity of fault zones observed in nature and the large size of the calculation cells in ...

Active Plume, Abandoned Ridge, or Ancient Slab? olivine‐Hosted Melt Inclusions Record the Mantle Melting Conditions Below the East Pacific Revillagigedo Archipelago, Mexico

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The voluminous active volcanoes of the Revillagigedo Islands of Socorro and San Benedicto in the east Pacific Ocean exhibit hotspot geochemistry. However, the presence of a deep mantle plume has not been seismologically confirmed. Instead, a fossil subducted slab is identified in the lower mantle underneath the volcanoes. Moreover, the islands

The dentition of the Late Jurassic dwarf sauropod Europasaurus holgeri from northern Germany: ontogeny, function, and implications for a rhamphotheca-like structure in Sauropoda [PDF]

PeerJ
The basal macronarian sauropod Europasaurus holgeri is known only from the Late Jurassic of the Langenberg Quarry near Goslar, Lower Saxony, Germany. Europasaurus has been identified as an insular dwarf and shows a clear resemblance to Camarasaurus and ...

Effect of the Content and Ordering of the sp² Free Carbon Phase on the Charge Carrier Transport in Polymer-Derived Silicon Oxycarbides

Molecules, 2020
The present work elaborates on the correlation between the amount and ordering of the free carbon phase in silicon oxycarbides and their charge carrier transport behavior. Thus, silicon oxycarbides possessing free carbon contents from 0 to ca.

On New Alkaline Sulfatometallates: Cs6[(WO2)2O(SO4)4], K8[(MoO2)2(SO4)6], K7.9Sr0.1[(WO2)2(SO4)6] and Na4[MoO2(SO4)3]

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
Two new alkaline sulfatometallates show promising optical absorption, emission and even non‐linear optical properties together with an astonishingly high thermal stability. The new sulfatotungstate Cs6[(WO2)2O(SO4)4] exhibits a hitherto unknown anion with an unusual W–O–W angle of 180° and edge‐sharing WO6 and SO4 polyhedra.

Initiation of the Ferrar Large Igneous Province Started in Southern North Victoria Land, Antarctica, With Shallow Emplacement of Sills Causing Magma‐Soft‐Rock Interaction and Phreatomagmatic Eruptions

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Early Jurassic volcanism was in the southern north Victoria Land portion of the Ferrar Large Igneous Province preceded by multiple phases of shallow‐level intrusions of Ferrar sills into the 300 m thick cover of sedimentary rocks of the Triassic‐Jurassic Victoria Group.

Ordering of tetrahedral and octahedral layers in synthetic lepidolites and Li-muscovites: two-dimensional {¹H} → ²⁹Si ∕ ²⁷Al CPMAS HETCOR and {¹⁹F} → ²⁹Si ∕ ²⁷Al CPMAS HETCOR spectroscopy [PDF]

European Journal of Mineralogy
Cationic ordering in the octahedral and tetrahedral sheets of synthetic lepidolites with composition K(LixAl3−x)[Si2xAl4−2xO10](OH)yF2−y and Li-muscovites with K(LixAl2-x/3□1-2x/3)[Si3AlO10](OH)yF2−y has been investigated using two-dimensional (2-D) {1H ...

RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 181-199, March 2026.
Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.
