Late Cretaceous Tectono-Metamorphic Events in the Skyros Upper Metamorphic Unit (Olympus Mountain), Aegean Sea, Greece

open access: yesGeosciences
Late Cretaceous metamorphic events are known in Crete and the Cyclades from klippen above the External Hellenides. This work extends their occurrence to the North Aegean area within the tectonic units of the Internal Hellenides.

STIM2β is a Ca2+ signaling modulator for the regulation of mitotic clonal expansion and PPARG2 transcription in adipogenesis

open access: yesThe FEBS Journal, EarlyView.
STIM2β acts as the intracellular Ca2+ regulator during adipogenesis. By inhibiting intracellular Ca2+ levels and SOCE, STIM2β promotes mitotic clonal expansion in the early stage of adipogenesis. In the terminal differentiation stage, increased SOCE activity enhances PPARG2 gene transcription.

U-Pn geochronology of deformed metagranites in central Sutherland, Scotland: evidence for widespread late Silurian metamorphism and ductile deformation of the Moine Supergroup during the Caledonian orogeny [PDF]

open access: yes, 2003
Within the Caledonides of central Sutherland, Scotland, the Neoproterozoic metasedimentary rocks of the Moine Supergroup record NW-directed D2 ductile thrusting and nappe assembly, accompanied by widespread tight-to-isoclinal folding and amphibolite ...

Renewable Resources as Promising Materials for Obtaining Graphene Oxide-like Structures

open access: yesNanomaterials
Currently, one of the topical directions in the field of production and application of graphene-like nanostructures is the use of renewable natural raw materials, which have unlimited resources for an economically efficient large-scale yield of a product

Coupling Phase Equilibrium Modelling and Apatite‐in‐Garnet Elastic Barometry to Unravel the P–T Path of the Micaschist Unit From the Zicavo Metamorphic Complex (Corsica, France)

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

西南日本の熱変成超苦鉄質岩体中のかんらん石と輝石の組成変化に関する覚書 [PDF]

open access: yes, 2010
This short article presents some diagrams showing the compositional variations of primary and metamorphic olivine, orthopyroxene and clinopyroxene in peridotites and serpentinites from thermally metamorphosed ultramafic complexes in SW Japan. In contrast

Building of the Deep Gangdese Arc, South Tibet: Paleocene Plutonism and Granulite-Facies Metamorphism

open access: yes, 2013
The Nyingchi complex, forming the eastern segment of the Gangdese magmatic arc, occurs within the southern Lhasa terrane in south Tibet, and is composed dominantly of plutons and their metamorphosed equivalents.Together with some metasedimentary units ...

Zircon (Re)crystallization During Metamorphism: Zircon Paragenesis in the Papua New Guinea Coesite Eclogite Revisited

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT The youngest known ultrahigh‐pressure (UHP) eclogite from Tumagabuna Island, a small island of the D'Entrecasteaux Islands chain in Papua New Guinea, exhibits zircon U–Pb age variations spanning a few million years. This age variation complicates the interpretation of the evolution of this high and ultrahigh‐pressure ([U]HP) terrane.
