“…Carbonate complexation may also contribute to the non-discriminate release of Y-Ho and La-Pr at higher pH. Although carbonate concentrations (not measured) are expected to be quite low in these experimentsgiven the initial soil pH (Table 1), some REY complexation by carbonate ions is likely in the higher pH range of our experiments (Cantrell and Byrne, 1987;Ohta and Kawabe, 2000;Quinn et al, 2006b). Aqueous carbonate complexation has been shown to influence total REY partitioning to Fe oxyhydroxide phases as well as to influence Y-Ho fractionation (Quinn et al, 2006b).…”

Ho forms stronger aqueous carbonate complexes than does Y (Liu and Byrne, 1995) and data from Quinn et al (2006b) suggest increasing aqueous carbonate concentrations-as well as increasing pH-in the presence of Fe oxyhydroxides decreases the difference between Ho and Y aqueous-solid partition coefficients (e.g.,log i K Preferential Y and La release extends to the lowest pH values in our experiment in the surface soils.…”

“…Fluid REE concentrations are also controlled by sorption onto clay mineral surfaces, Feoxides and carbonates Quinn et al, 2006), and this effect is increased as temperature decreases (Bau, 1991). Thus, partitioning of REE into secondary minerals formed during low temperature re-equilibration, or sorption onto mineral surfaces present along an eastward flow path, could explain lower REE concentrations in Seyferth and SVHS fluids on the eastern side of the valley compared to LCMV.…”

Characterizing the geothermal system at Surprise Valley (SV), northeastern California, is important for determining the sustainability of the energy resource, and mitigating hazards associated with hydrothermal eruptions that last occurred in 1951. Previous geochemical studies of the area attempted to reconcile different hot spring compositions on the western and eastern sides of the valley using scenarios of dilution, equilibration at low temperatures, surfaceevaporation, and differences in rock type along flow paths.These models were primarily supported using classical geothermometry methods, and generally assumed that fluids in the Lake City mud volcano area on the western side of the valley best reflect the composition of a deep geothermal fluid. In this contribution, we address controls on hot spring compositions using a different suite of geochemical tools, including optimized multicomponent geochemistry(GeoT) models, hot spring fluid major and trace element measurements, mineralogical observations, and stable isotope measurements of hot spring fluids and precipitated carbonates. We synthesize the results into a conceptual geochemical model of the Surprise Valley geothermal system, and show that high-temperature (quartz, Na/K, Na/K/Ca) classical geothermometers fail to predict maximum subsurface temperatures because fluids reequilibrated at progressively lower temperatures during outflow, including in the Lake City area. We propose a model where hot spring fluids originate as a mixture between a deep thermal brine and modern meteoric fluids, with a seasonally variable mixing ratio. The deep brine has deuterium values at least 3 to 4‰ lighter than any known groundwater or high-elevation snow previously measured in and adjacent to SV, temperature re-equilibration during west to east flow is the major control on hot spring fluid compositions, rather than dilution, evaporation, or differences in rock type.

“…Because plagioclase is one of the most chemically resistant minerals (Stefansson, 2001), the Eu anomalies may suggest an incomplete dissolution of volcanic products in seawater; • The absence of evident tetrad effects (ranging 0.8 6 t 3 6 1.0) for the Gd-Ho tetrad suggests that dissolved REEs exist as strong dissolved complexes in the studied water masses. Under these conditions they are involved in adsorption processes on SPM surfaces as outer sphere organic complexes (Takahashi et al, 1999;Davranche et al, 2004Davranche et al, , 2005, or are subjected to competition between carbonate complexation and surface complexation on surface of suspended particles (Quinn et al, 2006).…”

This paper presents the results of a study based on data collected during the oceanographic cruise ANSIC 2001 carried out in the Ionian Sea during the explosive activity of Mount Etna in the summer of 2001. Anomalous low values of Y/Ho ratios in seawater suggest extensive scavenging processes on the surfaces of smectitic alteration products, with Y and Ho fractionation controlled by the differences in their electronic configurations and behaviour during solution/surface complexation equilibria. These processes can also be traced through the presence of significant tetrad effects recorded in the chondrite-normalised Rare Earth Elements and Yttrium (YREEs) patterns of suspended particulate matter. This suggests that the preferential Y scavenging from seawater is due to the formation of inner-sphere complexes with OH À groups on montmorillonite crystal surfaces. The preliminary results of kinetic experiments of YREE released from volcanic ash to coexisting seawater, and the related effects on Y/Ho ratios and Ce anomalies, are consistent with the fractionation of Light Rare Earth Elements (LREEs) with respect to Heavy Rare Earth Elements (HREEs) observed in dissolved phase. They suggest a behaviour of Y similar to that reported for LREEs, particularly for Ce and Pr.
