Experimental Determination of Spinel / Melt , Olivine / Melt
Introduction Experimental studies have identified spinels as important hosts phases for many of the highly siderophile elements (HSE) [1-4]. Yet experimental studies involving chromite or Cr-rich spinel have been lacking. Experimental studies of partitioning of HSEs between silicate, oxides and silicate melt are plagued by low solubilities and the presence of small metallic nuggets at oxygen fu...
متن کاملControl of Slag and Insoluble Buildup in Ladles, Melting and Pressure Pour Furnaces
Introduction: During the past 30 years, the melting methods and associated molten metal-handling systems used by the U.S. foundry industry have changed significantly. During the same period, while ductile iron production has experienced continued growth, the quality of metallic scrap and other ironunit feed stocks has steadily deteriorated. The result: slag related melting problems have become ...
متن کاملWater diffusion in dacitic melt
H2O diffusion in dacitic melt was investigated at 0.48–0.95 GPa and 786–893 K in a piston-cylinder apparatus. The diffusion couple design was used, in which a nominally dry dacitic glass makes one half and is juxtaposed with a hydrous dacitic glass containing up to 8 wt.% total water (H2Ot). H2O concentration profiles were measured on quenched glasses with infrared microspectroscopy. The H2O di...
متن کاملBubble growth in rhyolitic melt
We report experimental data of bubble growth in natural rhyolitic melt with 1.4^2.0 wt% initial total H2O at 0.1 MPa and 500^6003C. Growth of many bubbles is monitored in every experiment. Bubble growth rate increases with temperature and initial total H2O. At a given temperature and initial total H2O, bubble growth rate also increases slightly with bubble size. The average growth rate for bubb...
متن کاملTrapped Melt in the Josephine Peridotite: Implications for Permeability and Melt Extraction in the Upper Mantle
Tabular dunites in the Josephine peridotite of southwestern Oregon represent conduits for melt extraction from the upper mantle. The amount of melt trapped within these channels during cooling and exhumation of the peridotite massif was calculated using a mass-balance approach. These calculations suggest that no more than 0·1^0·2 vol. % melt could have been trapped within these dunites after cr...
