An eclogite and its surrounding gneiss from the Malpica-Tuy zone, northwestern Spain, were studied. The eclogite contains besides garnet and omphacite, barroisitic amphibole, quartz, phengite with Si contents between 3.27 and 3.45 per formula unit (pfu), rutile, and accessory phases such as talc and (clino)zoisite-epidote. Garnet exhibits a chemical zonation with Alm59Prp13Grs24Sps4, Alm57Prp13...

Introduction: The petrogenesis of the low-Ti lunar ultramafic glasses is critical to the understanding of volcanic processes on the Moon. Popular petrologic models developed to explain the formation of these glasses involve high pressure melting of a variety of sources, including primordial, garnet bearing, lunar mantle and depleted lunar magma ocean (LMO) cumu-lates [1,2,3,4]. Following the hi...

A 10-mm cavity length magnetooptically Q-switched Nd:GdVO4 laser was demonstrated using a single-crystalline ferrimagnetic rare-earth iron garnet film. To design the Q-switching system, the magnetic, optical, and magnetooptical properties of the garnet film were measured. The diode pumped solid-state laser cavity was constructed using a 190-μm-thick garnet film with 58% transmittance. The garne...

in the contact metamorphic aureole of the next to the granodiorite intrusive body in the hassan-abaad village of yazd, high frequency garnet in different metamorphic zones is notable, which some contain garnet crystal with obvious zoning. obtained data from core to rim of garnet by sem point analysis, show that garnet crystals belong to grandite series, and sharp variation of al and fe from cen...

Recent work in Barrovian metamorphic terranes has found that rocks experience peak metamorphic temperatures across several grades at similar times. This result is inconsistent with most geodynamic models of crustal over-thickening and conductive heating, wherein rocks which reach different metamorphic grades generally reach peak temperatures at different times. Instead, the presence of addition...

the formation of atoll garnet in hornblende schists from the contact aureole of mashhad granite,ne iran, is discussed using textural and chemical data. these data suggest the possibility of incipientreplacement of pre-existing idioblastic garnet from the core. in addition, the presence of chlorite and calcite inthe core of atoll garnet reveal the retrograde nature of atoll formation.

The portability of new miniaturized devices, together with their ability to connect conveniently to networks in different places, makes mobile computing possible. Recent advances that have led to increasing bandwidths, for wireless communications, enable mobile users to utilize a vast range of sophisticated services such as real-time collaborative services. Garnet Collaborative system is a univ...

Introduction: Although the Lunar Magma Ocean (LMO) hypothesis has achieved wide acceptance in the lunar science community, it has never been fully tested experimentally. Presented here are the first results of equilibrium crystallization experiments using the Taylor Whole Moon (TWM) composition [1]. The first mafic cumulates in this LMO are dominated by forsteritic olivine, low-Ca pyroxene and,...
