An Upper Devonian foredeep basin in the Southern Central Iberian Zone (Variscan Iberian Massif): Consequences for Variscan plate dynamics [PDF]
New field research and revision of previous works in the Variscan Iberian Massif unravel the existence of an Upper Devonian foredeep basin in the southern Central Iberian Zone, close to the suture area with the Ossa-Morena Zone.

Fish Scales: A Multifunctional Biomaterial from Nature
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 ...

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

New data about the age of the Dershor Formation (Lower Devonian) on the Chernyshev swell (Timan-Pechora petroleum province) [PDF]
Lithological and biostratigraphical studies of the stratotyp section of the Lower Devonian Dershor Formation, represented in outcrops in the north of the Chernyshev swell, have been carried out. In the section of the Dershor Formation, a sequence of five

The Middle and Upper Devonian (Givetian and Frasnian) deposits of the Łysogóry-Radom and Lublin basins (south-central Poland) presented a diversified palynomorph assemblage. Numerous miospore taxa were documented and also contained well-preserved and varied plant remains, scolecodonts, acritarchs, chitinozoans, organic tentaculitoids, and bioclasts of ...

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 ...
