To better understand the genetic relationship between granitoid rocks of Archean cratons and underlying 'keel' subcratonic lithospheric mantle (SCLM), we have conducted two types experiments in a multi-anvil apparatus at 3–4 GPa: (1) peridotite assimilation experiments, which natural, hydrous TTG (trondhjemite–tonalite–granodiorite) melts are reacted with relatively high melt–rock ratios; (2) liquidus saturation on Mg-rich diorite (sanukitoid) melts. Our results demonstrate that liquids...

We performed a thermodynamic and experimental study to investigate the fate of pyroxenite-derived melts during their migration through peridotitic mantle. used simplified model interaction in which peridotite is impregnated by then equilibrated with finite amount liquid. considered two pyroxenite compositions three contexts pyroxenitic melt impregnation: (1) subsolidus lithospheric mantle; (2) beneath mid-ocean ridge (MOR) asthenospheric mantle at high pressure; (3) MOR partially molten...
The ATLAS collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing and vacuum pipe of Large Hadron Collider. extreme operating conditions at this location have necessitated development radiation hard sensor technologies front-end readout chip, called FE-I4. Planar sensors 3D been investigated to equip layer, prototype modules using FE-I4A fabricated characterized 120 GeV pions CERN SPS 4 positrons DESY, before after module...
Magnesian calcites are important components of sediments and biominerals. Although Raman spectra calcite, dolomite, magnesite well known, those magnesian deserve further investigation. Nineteen syntheses covering the range 0–50 mol% MgCO3 have been carried out at high pressure temperature (1–1.5 GPa, 1000–1100 ℃). The crystalline run products characterized by μ-Raman spectroscopy.
There is increasing evidence that the primary magmas at origin of low-silica alkaline volcanism, such as basanites, are very rich in CO2 and they can rise rapidly, directly from mantle to Earth&#8217;s surface. Such volcanic systems numerous intraplate oceanic continental settings, including French Massif Central, some remarkable for abundance large mantle-derived xenoliths. Although usually represent relatively modest volumes magma, their eruptions constitute a real specific threat...
Rapid decompression experiments were performed to study homogeneous bubble nucleation in a crystal‐free rhyolitic liquid at 800°C. Bubble was produced by lowering the pressure 1–10 MPa s −1 from an initial value between 200 and 295 final below volatile saturation P Sat . Six compositions with 4.1–7.7 wt % H 2 O 10–1200 ppm CO investigated. For each composition we determined critical HoN which can proceed. The samples quenched showed nucleated core large number of uniformly spaced bubbles....
