Textural, major element and trace element data for xeno-liths from Salt Lake Crater, Hawaii indicate that typical four phase lherzolite inclusions (olivine, orthopyroxene, chrome diopside and spinel) found worldwide in basalts are not samples of primitive upper mantle. Rather, lherzolite may be the recrystallized residue left after a basaltic melt extracts the easily fused components from pre-e...

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...

the ali-abad porphyry copper deposit is located in the central iranian magmatic belt. as a result of subduction magmatism, oligo-miocene leucogranitoid rocks have intruded into conglomerates of lower cretaceous age. due to contact metamorphism the following mineral assemblage has occurred in the altered conglomerate: garnet (andradite-grossular) + epidote+ quartz + calcite + pyrite skarnificati...
