PALEOTECTONIC AND PALEOGEOGRAPHIC CONDITIONS FOR THE ACCUMULATION OF THE LOWER RIPHEAN AI FORMATION IN THE BASHKIR UPLIFT (SOUTHERN URALS): THE TERRANECHRONE® DETRITAL ZIRCON STUDY

Геодинамика и тектонофизика, 2018
The TerraneChrone® (LA-ICP-MS) technique has been applied to carry out an integrated study of detrital zircons in sandstones sampled from the basal horizons of the stratotypical Riphean sequence in the Southern Urals, specifically the Navysh and Chudin ...

Time lag between metamorphism and crystallization of anatectic granites (Córdoba, Argentina)

Geologica Acta, 2020
SHRIMP and LA-ICP-MS analyses carried out on zircons from the Río de los Sauces granite revealed their metamorphic and igneous nature. The metamorphic zircons yielded an age of 537±4.8 (2σ)Ma that probably predates the onset of the anatexis during the ...

Age and genetic interrelation of ultramafic rocks, rodingites and chlorite-carbonate rocks of the Karabash massif (South Urals)

Литосфера, 2016
The age of ulramafic rocks of the Karabash massif (1720-1740 Ma), the minimum age of their protolith (1830 Ma), and the age of formation of rodingites (438.5 ± 15 Ma) and chlorite-carbonate rocks (404.4 ± 8.8 Ma) were determined on the basis of the ...

Thermoluminescence of zircon: a kinetic model [PDF]

Journal of Physics: Condensed Matter, 2003
The mineral zircon, ZrSiO4, belongs to a class of promising materials for geochronometry by means of thermoluminescence (TL) dating. The development of a reliable and reproducible method for TL dating with zircon requires detailed knowledge of the processes taking place during exposure to ionizing radiation, long-term storage, annealing at moderate ...

Klotho‐Derived Peptide 1 Protects against Acute Kidney Injury by Directly Targeting Mitochondrial ATAD3A

Advanced Science, EarlyView.
This study uncovers that KP1, a Klotho‐derived peptide, protects the kidney against acute kidney injury, a clinical syndrome with high morbidity and mortality. KP1 enters tubular epithelial cells via endocytosis, directly interacts with the mitochondrial ATAD3A/HIGD2A complex, thereby preventing cytochrome c release, and caspases activation, and ...

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

The Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Hf isotopes from Palawan Continental Terrane, Philippines-clues to the evolution of sediment sources

Terrestrial, Atmospheric and Oceanic Sciences, 2018
The age spectra of detrital zircons in meta-sediments from Palawan Island, Mindoro Island, Tablas, and the Buruanga Peninsula of Panay Island in the Central Philippines provide evidence for the provenance of these zircons in the northern part of the ...

Lattice and Surface Engineering of Transition Metal Oxide Photoanodes for Efficient Photoelectrochemical Water Splitting

EcoEnergy, EarlyView.
This review highlights phase control, facet control, and atomic vacancy engineering as key strategies to enhance charge transport, light harvesting, and surface activity in PEC photoanodes. ABSTRACT Photoelectrochemical (PEC) water splitting is a promising approach for converting solar energy into hydrogen, yet the performance of transition metal oxide
