The formation of atoll garnet in the Ardara aureole, NW Ireland, is discussed using the textural, chemical and Electron Backscatter Diffraction (EBSD) data. Textural evidence suggests the possibility of incipient of garnet replacement from the core. In addition, the presence of staurolite and andalusite in the core of small atoll garnets as well as the occurrence of sillimanite in the core of l...

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.

Abstract Garnet commonly accommodates high contents of Mn + Y heavy rare earth elements (HREE) that follow Rayleigh fractionation during garnet early growth, with the exception overstepping nucleation (late crystallization owing to reaction overstepping). Because this, as porphyroblasts form mostly in equilibrium surrounding matrix, concentration these continuously decreases towards porphyrobla...

The distribution coefficient KD=(Mg / Fe)garnet/(Mg/Fe)biotite has been calculated for eight garnet-biotite pairs from rocks ranging from the garnet isograd to the staurolite zone along the Stonehaven coast of NE Scotland. This distribution coefficient depends upon metamorphic temperature and is not dependent upon the Mn and Ca content of garnet. Garnet-biotite geothermometer yields temperature...

Radiation doses calculated for people resettling Bikini Island at Bikini Atoll, Enjebi Island at Enewetak Atoll, Rongelap Island at Rongelap Atoll, and Utrōk Island at Utrōk Atoll are presented. Residence is assumed to begin in 2010. In previous dose assessments it was shown that (137)Cs accounts for about 98% of the total dose for returning residents. About 85 to 90% (depending on the atoll) i...

The degree of 137 Cs root uptake into tropical fruits, vegetables and native foliage from coral atoll soils in the Marshall Islands has been quantified using soil-to-plant transfer factors. Transfer factor values for different plants on Bikini Island (Bikini Atoll) range between 0.2 and 144 and, in general, are considerably higher than those observed in continental soils. In this paper we will ...

The goal of the ATOLL System Area Network (SAN) is the optimization of a communication system for cluster computing with respect to the following qualities: performance, cost, simplicity of use and general applicability. The design provides many new and unique features, which makes ATOLL an enabling technology in the area of cluster computing. After finishing the ATOLL design space analysis our...
