Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
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 ...

Sedimentological analysis and hydrocarbon potential of the upper devonian-lower carboniferous Tahara sandstones, ghadames basin, western Libya [PDF]

, 1998
The Palaeozoic (Upper Devonian-Lower Carboniferous) Tahara Formation, western Libya, was deposited in shallow-water, marginal and nearshore marine environments influenced by waves and storms.

Facies-succession and architecture of the third-order sequences and their stratigraphic framework of the Devonian in Yunnan-Guizhou-Guangxi area, South China

Journal of Palaeogeography, 2013
The Caledonian orogeny at the end of the Silurian resulted in great changes in the palaeogeography in the Yunnan-Guizhou-Guangxi area of South China; the continental area of the Early Paleozoic evolved into the extensive Dian-Qian-Gui Sea in the Late ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Enhanced continental weathering and its marine environmental effects in the late Devonian: Constraints from strontium isotopes of carbonate rocks in South China

地质科技通报, 2022
The Frasnian-Famennian extinction in the late Devonian was one of the largest mass extinction during Earth's history, which was believed to be caused by the plant landing-indued intensification of terrestrial chemical weathering and the consequent ...

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

Journal of Quaternary Science, EarlyView.
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.

Reservoir characterization and potential of the old red sandstone around the inner moray firth, NE Scotland [PDF]

, 1993
Old Red Sandstone deposition in North East Scotland occurred during Devonian times within the Orcadian Basin, a northeast-southwest elongated structure. The basin formed in an extensional tectonic regime that resulted from gravitational collapse of over ...

G2‐PASE: A Novel, Rapid, and Reliable Measure of Plaque Psoriasis Severity

JEADV Clinical Practice, EarlyView.
ABSTRACT Background The Psoriasis Area and Severity Index (PASI), a composite measure of plaque psoriasis disease severity, is commonly used to determine treatment eligibility and response, but is time consuming for every‐day clinical use. The Gulliver‐Gestalt‐Psoriasis Area Severity Estimate (G2‐PASE) was developed to approximate PASI scores using ...

Geochemical Characteristics and Their Geological Significance of Zircon and Apatite From the Wunugetushan Porphyry Cu–Mo Deposit, Inner Mongolia, NE China

Acta Geologica Sinica - English Edition, EarlyView.
The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo

High-resolution isotope stratigraphy of the Lower Devonian.

, 1996
A new data set of 53 $\sp‡$Sr/$\sp†$Sr ratios for the Lower Devonian has been collected from well preserved, and stratigraphically well constrained, brachiopod shells from the Leon region in Spain, western Urals in Russia, Podolia in ...
