Metasomatites of medium and mafic composition from Nyaschevo massif (Ilmeny Mauntains, South Urals)

open access: yesЛитосфера, 2015
The results of the study of mediosiliceous and mafic metasomatites located in ultramafic and mafic rocks Nyaschevo massif presents in the paper. The texthural and structural features of these rocks allow to attribute them to tectonites - protomylonites and

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 238-258, April 2026.
ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Cistanche tubulosa Extract Protects Cast Immobilization‐Induced Declines of Muscle Strength and Muscle Mass

open access: yesTraditional &Kampo Medicine, Volume 13, Issue 1, April 2026.
ABSTRACT Aim One of the effects of Cistanche herb is described in the Chinese Pharmacopoeia as for lack of strength in muscles and bones. However, concrete evidence of this herb for muscle strength has been hardly reported. The present study aimed to clarify the effects of 30% ethanolic extract of Cistanche tubulosa fleshy stem on muscle strength and ...

Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 3, Page 200-225, April 2026.
ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.

Decoding Metamorphic Nanodiamonds Formation Through Their Internal Structures

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 3, Page 226-245, April 2026.
ABSTRACT Metamorphic diamonds offer insights into Earth's evolution, modulating the global carbon cycle through subduction into the mantle and exhumation. However, the formation and internal structure of minute diamonds remain poorly understood. Here, we study the internal structures of diamond‐bearing inclusions from the Eastern Alps using state‐of ...

Near‐Synchronous Cambrian Evolution of the Transbrasiliano‐Kandi‐4°50′ Shear Zone in South America and Africa

open access: yesTerra Nova, Volume 38, Issue 2, Page 97-105, April 2026.
ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

Dating C/S Structures in Syntectonic Granites by In Situ Rb‐Sr Analyses on Muscovite

open access: yesTerra Nova, Volume 38, Issue 2, Page 124-129, April 2026.
ABSTRACT The interplay of crystallisation, deformation and fluid–rock interactions makes deciphering geochronological information complex in syntectonic granites. In this study, we apply in situ Rb‐Sr analyses to selected samples from the Questembert Variscan syntectonic granite in Western France, which was emplaced along the South Armorican Shear Zone
