• Two stages of fluid exsolution are recognized in the Weijia W skarn deposit. F-rich magmatic fluids enriched REEs, Y, Nb, Ta with flat REE patterns. F consumption is critical for compositional evolution mineralizing fluids. Combined garnet and scheelite trace elements powerful tracking mineralization. Fluid an essential subject studies hydrothermal ore-forming processes. Garnet prevail W-bear...

The kinetics of the reaction of majorite plus ferropericlase to ringwoodite: Implications for mantle upwellings crossing the 660 km discontinuity a r t i c l e i n f o a b s t r a c t Keywords: 660 km discontinuity reaction kinetics perovskite ringwoodite majorite We have measured the kinetics of reaction between MgO and majoritic garnet at 20 GPa and 1773–2123 K as a proxy for the reaction bet...

Aim: To evaluate the efficacy of latanoprost for the prevention of ocular hypertension after neodymium: yttrium-aluminum-garnet laser posterior capsulotomy. Methods: Fifty six eyes of 56 consecutive patients receiving neodymium:yttrium-aluminum-garnet laser capsulotomy for posterior capsule opacification were randomized to group 1, who received 1 drop of latanoprost 0.005%, or to group 2, who r...

Seismic tomography reveals garnet-rich crust and mantle lithosphere descending into the upper mantle beneath the southeastern Sierra Nevada. The descending lithosphere consists of two layers: an iron-rich eclogite above a magnesium-rich garnet peridotite. These results place descending eclogite above and east of high P wave speed material previously imaged beneath the southern Great Valley, sug...

Triply doped Y3Al5O12: Ce3+, Pr3+, Cr3+ phosphors are prepared by solid state reaction. The emission spectra are enriched in the red region with the luminescence of both Pr3+ and Cr3+ through Ce3+ → Cr3+ and Ce3+ → Pr3+ → Cr3+ energy transfers. The properties of photoluminescence and fluorescence decay indicates larger macroscopic Ce3+ → Cr3+ transfer rates in the triply doped phosphors in comp...

chloritoid is crystallised with chlorite, white mica and garnet in chlorite zone metapelites ofthe regional metamorphic rocks of the sanandaj-sirjan metamorphic belt in southern iran. chemistry ofcoexisting minerals is studied using microprobe analysis. application of the chlorite-chloritoidgeothermometry gives temperatures of 515°c and 557°c. the chlorite-garnet fe-mg exchangegeothermometer in...

A new gem corundum occurrence has been discovered in the Naryn-Gol Creek placer of Dzhida volcanic field (Russia). In this deposit, sapphire associates with large crystals garnet, spinel, augite, olivine, enstatite, ilmenite, Ti-magnetite, and alkali feldspar. Such a combination minerals is typical for deposits associated basalts widely distributed Southeastern Asia Australia. We have also foun...
