Field evidences, petrographic features and geochemical studies show that the garnet-muscovite granitoids of Boland Parchin area are S-type and they have sharp contact with the host rocks (metamorphic rocks). Granitoids of Boland Parchin contain minerals such as quartz, K-feldspars, plagioclase, biotite and Al-rich minerals (such as muscovite and garnet). Chemical composition of K-feldspars, pla...

Abstract The major-element chemical composition of garnet provides valuable petrogenetic information, particularly in metamorphic rocks. When facing detrital garnet, information about the bulk-rock and mineral paragenesis initial garnet-bearing host-rock is absent. This prevents application thermo-barometric techniques calls for quantitative empirical approaches. Here we present a discriminatio...

A garnetite that occurs locally in phyllitic schists exposed by the Santorini caldera consists mainly of euhedral garnet crystals showing alternating isotropic and birefringent lamellae. X-ray diffraction revealed two garnets with unit cell dimensions a of I2.o52:ko-oo2 and I~'984-ko-oo5 A, corresponding respectively to almost pure andradite and a granditic phase. Mean compositions determined b...

Although predicted for light [1], wave bullets − stable two-dimensional nonlinear wave packets self-focused in space and time − were first experimentally observed in the system of spin waves in yttrium-iron garnet (YIG) films [2]. The experimental investigation of wave bullets in magnetic films has the advantage of direct two-dimensional access to the medium and of the possibility to follow the...

The nature of source rocks of basaltic magmas plays a fundamental role in understanding the composition, structure and evolution of the solid earth. However, identification of source lithology of basalts remains uncertainty. Using a parameterization of multi-decadal melting experiments on a variety of peridotite and pyroxenite, we show here that a parameter called FC3MS value (FeO/CaO-3*MgO/SiO...

OBJECTIVES A cost-effectiveness analysis was carried out comparing electrosurgical transurethral resection of the prostate (TURP) with holmium:yttrium-aluminum-garnet laser resection of the prostate (HoLRP). METHODS One hundred twenty patients with benign prostatic hyperplasia and urodynamically proved obstruction were randomized to undergo either TURP or HoLRP. Economic and clinical outcome ...

The formation of peralkaline melts is generally recognized to be related to enrichment of the mantle in sodium or potassium during a metasomatic event that predated magma generation. The wide range in mineral assemblages, mineral compositions, and fluid compositions in peralkaline melts are, to a large extent, a function of the sodium/potassium content of these mantle-metasomatizing fluids, whi...

Mass attenuation coefficients and partial photon interactions have been calculated theoretically at incident photon energy 1 Kev to 100 GeV for garnet series of gemstones (Grosaularite (GS1), Pyrope(GS2), Spessarlite(GS3), Almandine(GS4), Uvarovite(GS5) and Androdite(GS6) using XCOM software [1]. The values of these parameters have been found to change significantly with incident photon energy ...

Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...
