Different desorption types and geological influencing factors of Silurian shale gas in southeastern Sichuan Basin

open access: yesShiyou shiyan dizhi
The southeastern Sichuan Basin is a key area for the exploration and development of Silurian shale gas in China. In recent years, a number of shale gas wells have achieved good exploration results in this area, providing important support for the ...

AI‐assisted identification of stromatoporoids

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
AI models integrating vertical and transverse thin‐section images accurately classify Silurian stromatoporoid taxa, achieving up to 97% accuracy. This dual‐orientation framework mirrors traditional taxonomy, reveals patterns of morphological continuity, and provides a scalable, quantitative approach for advancing automated fossil identification ...

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

ORGANIC GEOCHEMICAL ASSESSMENT AND SHALE GAS POTENTIAL OF LOWER SILURIAN ORGANIC RICH SHALE IN THE GHADAMES BASIN, NORTH AFRICA; pp. 337–352 [PDF]

open access: yesOil Shale, 2019
The Silurian organic rich shale is the main source of hydrocarbons in the Ghadames Basin in North Africa. The basin has been widely characterized as a source rock for Ordovician oil and gas; yet understanding this shale as a shale resource play remains ...

Geochronological Constraints on Diachronous Post‐Collisional Slab Breakoff Along the Paleo‐Tethyan Sutures

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The slab breakoff model is a preferred geodynamic interpretation for post‐collisional exhumation and associated magmatic flare‐ups. In this study, rutile U–Pb dating of retrograde eclogites revealed distinct stages of exhumation along the Paleo‐Tethyan sutures in southwest China. The studied samples yielded ages of 246.7 ± 8.5 and 239.7 ± 14.0

Reservoir characterization and exploration potential of shale reservoir near denudation area: A case study of Ordovician–Silurian marine shale, China

open access: yesOpen Geosciences
The distribution of denudation areas has brought huge risks to the exploration and development of deep buried shale gas resources. The reservoir characterization and exploration potential near denudation areas is of great significance to the evaluation ...

Some new palynomorphs from the Silurian of the Quetame Massif, Cordillera Oriental, Colombia, South America

open access: yesBoletín Geológico, 1994
During a palynological investigation of Paleozoic series in the Colombian Cordillera Oriental Silurian-indicating fossils were found in Colombia. In this paper we describe four palynomorphs which were significant for the Silurian of the Quetame Massif.

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 3, Page 625-647, September 2026.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

open access: yesiMeta, Volume 5, Issue 4, August 2026.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.
