Abstract Archean (4.0–2.5 Ga) tonalite–trondhjemite–granodiorite (TTG) terranes represent fragments of Earth’s first continents that formed via high-grade metamorphism and partial melting hydrated basaltic crust. While a range geodynamic regimes can explain the production TTG magmas, processes by which they separated from their source acquired distinctive geochemical signatures remain uncertain...

The garnet megacrysts of Gore Mountain (Adirondacks, US) are world-renown crystals due to their size, up 1 m in historical record, which makes them the largest known garnets on planet. We show here that they also host first primary inclusions trondhjemitic melt found natural mafic rocks. petrological and experimental investigation inclusions, coupled with phase equilibrium modelling, shows this...

Abstract In shallow sea, the effect of geoacoustic characteristics seabed sediments on acoustic propagation cannot be neglected, which is closely related to detection and inversion. Aiming at problem low-frequency propagation, sound pressure sensitivity kernel (PSK) travel-time gradient (TTG) field for parameters sediment were presented by using normal mode model perturbation approximation. Com...

BACKGROUND AND AIMS Tissue transglutaminase (tTG) is an autoantigen in coeliac disease and the related disorder, dermatitis herpetiformis. The detection of autoantibodies directed against tTG is a highly specific marker of coeliac disease; however, it is unclear if there is a role for these autoantibodies in the disease process. The aim of this study was to investigate whether the catalytic tri...
