Schist Belts of the Benin‐Nigeria Shield Reveal a Neoproterozoic History

Terra Nova, EarlyView.
ABSTRACT Belts of metasedimentary rocks (schist belts) in the Benin‐Nigeria Shield (BNS) are investigated for the first time using U–Pb dating and Lu‐Hf isotope analysis of detrital zircons. We report maximum depositional ages that place their deposition firmly in the Neoproterozoic and link them with strata in the Dahomey Belt, the central African ...

Preservation of Garnet Growth Zoning and the Duration of Prograde Metamorphism

, 2010
Chemically zoned garnet growth and coeval modification of this zoning through diffusion are calculated during prograde metamorphic heating to temperatures of up to 8508C.This permits quantification of how the preservation or elimination of zoning ...

Intermittent Brittle and Ductile Deformation as Recorded by Dating of Ultramylonites and Pseudotachylytes in Extending Continental Crust (Ivrea‐Verbano Zone, Italy)

Terra Nova, EarlyView.
ABSTRACT Mylonites and pseudotachylytes play a crucial role in defining the rheology of extending continental crust. In this context, determining the age of brittle‐ductile deformation is fundamental to understanding the rifting evolution stages. Here, we investigate the Premosello Shear Zone, an extensional structure of the Ivrea‐Verbano lower crust ...

Vapor flux and recrystallization during dry snow metamorphism under a steady temperature gradient as observed by time-lapse micro-tomography

, 2012
Dry snow metamorphism under an external temperature gradient is the most common type of recrystallization of snow on the ground. The changes in snow microstructure modify the physical properties of snow, and therefore an understanding of this process is ...

Long‐Lasting Plutonism During Orogenic Cycles: Incremental Emplacement of the Variscan Bassiès Pluton (Central Pyrenees, France)

Terra Nova, EarlyView.
ABSTRACT Laser ablation U–Pb single zircon geochronology was applied to four peraluminous granite and granodiorite samples from the Bassiès pluton in the Central Pyrenees (France) yielding a wide range of concordant ages from early Carboniferous (Tournaisian, 351 Ma) to early Permian (Artinskian, 285 Ma).

Endothelial TRPV4–Cx43 signalling complex regulates vasomotor tone in resistance arteries

The Journal of Physiology, EarlyView.
Abstract figure legend In this study, we investigate, for the first time, the role of endothelial Cx43 hemichannels (hCx43) in the regulation of vasomotor tone. We discovered that TRPV4 channels and Cx43 are in proximity within the endothelium of mouse arterioles.
