“…4). This is surprising as Li is usually considered relatively incompatible in garnet, with Li partition coefficients D grt-fluid in the range 0.005-0.008 (Brenan et al, 1998;Marschall et al, 2007a). A plausible explanation for the Li decrease during prograde garnet growth is a coupled substitution of Li + and HREE 3+ with 2 Mg,Fe 2+ .…”

“…A detailed fluid inclusion study by Herms et al (submitted) Global subducted sediment has Li concentrations of 2-75 ppm (Bouman et al, 2004) and a mass-weighted mean of 43.3 ppm Li (Chan et al, 2006), and sediment-derived fluids would be even more enriched if a mineral-fluid partition coefficient of 0.2 (Brenan et al, 1998) were taken into account. Subducted metasediments may contain >10 modal % of chlorite (Li et al, 2008), which can incorporate significant amounts of Li (up to 100 ppm; Bebout et al, 2007).…”

Two distinct types of eclogites from the Raspas Complex (Ecuador), which can be distinguished based on petrography and trace element geochemistry, were analyzed for their stable (Li, O) and radiogenic (Sr, Nd) isotope signature to constrain metasomatic changes due to fluid-overprinting in metabasaltic rocks at high-pressure conditions and to identify fluid sources. MORB-type eclogites are characterized by a relative LREE depletion similar to MORB. High-pressure (HP) minerals from this type of eclogite have highly variable oxygen isotope compositions (garnet: +4.1 to +9.

“…For instance, fluids are thought to be responsible for the mechanical softening or the partial melting of mantle rocks, which is related to the generation of mantle-derived magmas (Ulmer, 2001). In addition, fluids are excellent media for chemical transport (Brenan et al, 1998).…”

“…In aqueous fluid-related processes, however, the behavior of boron is in striking contrast to that of zirconium, niobium, hafnium and tantalum. Boron is one of the most fluid-mobile elements during high-temperature fluid-rock interactions (Seyfried et al, 1984;Morris et al, 1990;Brenan et al, 1998). In contrast, zirconium, niobium, hafnium and tantalum, which are known as typical high field strength elements (HFSEs), are essentially fluid-immobile (Keppler, 1996;Kogiso et al, 1997).…”

An analytical technique for determining boron, zirconium, niobium, hafnium and tantalum contents in rock samples by inductively coupled plasma mass spectrometry (ICP-MS) is described. The rock samples (<30 mg) were decomposed with mannitol-added HF, and dissolved in a 0.015 M HF/0.12 M HNO 3 acid mixture for ICP-MS analysis. Boron, zirconium, niobium, hafnium and tantalum concentrations were measured by the internal calibration curve method using three internal standard elements, beryllium for boron, indium for zirconium and niobium, and rhenium for hafnium and tantalum. Seventeen rock reference samples from the Geological Survey of Japan and the U.S. Geological Survey were analyzed, and the determined concentrations showed good agreement with the reported values obtained by isotope dilution method, as well as with the recommended values. This technique is a simple method for the precise determination of boron, zirconium, niobium, hafnium and tantalum concentrations, and it has wide potential for geochemical application, particularly for the determination of boron.Keywords: ICP-MS, analytical method, rock reference samples, boron, high field strength elements 1990; Ishikawa and Nakamura, 1994;Ishikawa and Tera, 1997;Tonarini et al., 2001). Although the isovalent element pairs zirconium-hafnium and niobium-tantalum have very similar ionic radii and generally behave coherently during magmatic processes, the Zr/Hf and Nb/Ta ratios of some mantle-derived igneous rocks deviate sub-
