• W2000792676 abstract "We have determined the concentrations and isotopic compositions of Sr and Nd in hydrothermal fluids from 21°N, East Pacific Rise and Guaymas Basin, Gulf of California. The purest solutions analyzed from 21°N exhibit a small range in Sr concentration between individual vents from 5.8 to 8.7 ppm, close to normal seawater Sr concentrations. They exhibit a small range in87Sr86Sr fromεSr(0) = −13.4 to −17.7, corresponding toεSr(0) ≈ −18 ± 2 in the pure hydrothermal end-member. These results indicate extensive but not complete isotopic exchange with Sr in the depleted oceanic crust (εSr(0) = −31.8) and suggest that Sr concentrations in these solutions are buffered. In contrast, the concentration and isotopic composition of Nd in solutions show large variations between vents. The concentration of Nd ranges from 20 to 336 pg/g (6–100 times seawater Nd concentrations). The isotopic composition ranges fromεNd(0) = −3.6 (similar to Pacific seawater) to +7.9. Many samples show substantial contributions from MORB, but all haveεNd(0) well below MORB at this locality (εNd(0) = +9.7) in spite of very large enrichments in Nd concentrations. While complete isotopic exchange withwater/rock≈ 2 or exchange with anomalous oceanic crust can explain the Sr data, the Nd data require exchange with a reservoir havingεNd(0) < Pacific seawater. Low-temperature reactions with metalliferous sediments on the ridge flanks may provide such a source. Both Sr and Nd in the Guaymas Basin solution are very different from21°N. εSr(0) = +11.0 andεNd(0) = −11.4 and are consistent with the fluid exchanging Sr and Nd with heated sediments having a substantial component of old continental detritus. Some irregularities in the Nd isotopic data reported here indicate that there must be a problem of contamination for some ultra-low-level trace elements during sample collection and processing which requires further attention. Using a simple box model, the estimates for hydrothermal Nd fluxes are compared with fluxes which would be required to maintain the relatively radiogenic value ofεNd(0) ≈ −3 in the Pacific against the influx of more negative Antarctic waters (εNd(0) ≈ −9). It is shown that the hydrothermal flux of Nd from mid-ocean ridges falls far short of that necessary to maintain the isotopic balance. This indicates that weathered material from volcanic terranes (εNd(0) ≈ +7) is the most reasonable major source of radiogenic Nd in the Pacific." @default.
