A Geophysical Crustal Model of Central Italy for Geoneutrino Predictions in Borexino

open access: yesEarth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Predicting the geoneutrino signal at underground detectors requires a local crustal reference whose precision matches the experimental uncertainty. The current Borexino reference is 15 years old and deterministic. We replace it with GUESS, a probabilistic 3‐D model of the Gran Sasso region, built by Bayesian inversion of multi‐source ...

FRASNIAN AND VISEAN-NAMURIAN CONODONT FAUNAS AT PRAPROTNO, SLOVENIA

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
Conodont faunas from the limestone pebbles of the Upper Paleozoic Conglomerate at Praprotno, Slovenia demonstrate the presence of two faunas. The older fauna, marked by Palmatolepis surecta and Polygnathus decorosus is indicative of the Frasnian stage ...

Geochemical Characteristics of Metasediment—Rich Lower Continental Crust: Insights From the Ivrea‐Verbano Zone (DIVE Drilling Project, ICDP Expedition 5071, Val d’Ossola, Italy)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract Whole‐rock geochemical data from two drill cores obtained through the ICDP (International Continental Scientific Drilling Program) funded Drilling the Ivrea‐Verbano Zone (IVZ) (DIVE) project: 5071_1_B (Ornavasso) and 5071_1_A (Megolo), provide new insights into the composition of the lower continental crust (LCC) in the IVZ. Borehole 5071_1_B (

Paleozoic origin of the cycads

open access: yes, 1976
Megasporophylls and associated plant parts from Upper Pennsylvanian and Lower Permian rocks of southwestern United States are interpreted as lineage of cycads, derived from pteridosperms.

The upper Paleozoic regional development of the Ottar basin from seismic 2D interpretation [PDF]

open access: yes, 2018
The Ottar basin is not yet formally defined, but is a known structural element situated under the Bjarmeland Platform in the southwestern Barents Sea, buried beneath thick, flay-lying Mesozoic strata. This thesis focuses on delineating the informal upper

Assessment of the possibility of gas hydrate formation in gas-bearing levels on the slopes of the Suntar uplift [PDF]

open access: yesНефтегазовая геология: Теория и практика
High oil and gas potential of the territory of the slopes of the Suntar uplift, a first-order structure in the east of the Siberian platform (Western Yakutia), is noted.

EMIT Reveals Elevated Calcite Signatures in Shorelines of Lake Powell and Lake Mead Exposed by Drought and Colorado River Management

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Nearly half of Earth’s seasonal freshwater storage variability occurs in human‐managed reservoirs, resulting in large areas of reservoir‐bed that are episodically inundated or subaerially exposed. Here we use hyperspectral data from NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission to map calcite mineral assemblages across ...
